A data-driven guide to Sigma IV, connectivity, infrastructure, real estate prices, rental yields, investment potential, and livability — for buyers, tenants, investors, and developers.
Pin code 201310 is the listed code for Sector Sigma 4 Greater Noida, on the Knowledge Park-I S.O delivery beat. No shop, school or clinic inside the sector could be found printing the code, so confidence is low. Treat 201310 as the working answer and confirm it against an official letter.
Up to a point. Sigma 4 sits on the same India Post beat as Sigma 1, Sigma 2 and Sigma 3, and every portal lists it under 201310. What is missing is a verified establishment address inside Sigma 4 itself. Without one, the code rests on the delivery beat and portal listings alone, which is why the confidence level is low rather than medium or high.
In practice that means 201310 is almost certainly right, but a new resident should still read the code off the first bank statement, gas connection letter or voter slip that arrives and use whatever India Post printed there.
Knowledge Park-I S.O, a sub office outside the sector, runs the delivery round for 201310. Alpha Greater Noida S.O appears against the same code as a counter office with no delivery role. Ghori B.O and Sakipur B.O are the branch offices. No alternate code surfaced for Sigma 4 in any listing, which at least removes the retired-code confusion that affects some neighbouring sectors.
Because 55 other sectors share the code, the sector name on the envelope matters more than the number. The number only steers a letter as far as the beat.
Its digits follow the national pattern: 2 for the northern zone, 20 for Uttar Pradesh, 201 for the Ghaziabad sorting district, which also serves Gautam Buddha Nagar, and 310 for the delivery office.
For a KYC form or an online checkout, a Sigma 4 resident writes: Flat [number], Tower [letter], [Society name], Sector Sigma 4, Greater Noida, Uttar Pradesh 201310. If a later official letter shows anything else, that printed code takes precedence.
Sector Sigma 4 Greater Noida is a residential sector in Greater Noida under GNIDA. It belongs to the Greek-letter residential belt, in the Sigma group between the Omicron sectors and the Ecotech 1 Extension and Ecotech 6 industrial belt. Kasna lies about 2.46 km away, on the same side of the city.
Sigma 4 marks the point where Greater Noida's Greek-letter housing begins to give way to its Ecotech factories. The Sigma group sits between the Omicron sectors and the industrial belt formed by Ecotech 1 Extension and Ecotech 6, and Sigma 4 is listed close to both sides.
The sector is administered by GNIDA, the Greater Noida Industrial Development Authority, in Gautam Buddha Nagar district of Uttar Pradesh. It is a residential sector, one of the four numbered parts of the Sigma group.
| Neighbor | Side/Relationship | Evidence |
|---|---|---|
| Sigma I, Sigma II, Sigma III | Same letter group, nearby | Locality listings |
| Ecotech I Extension | Industrial belt, nearby | Locality listing |
| Omicron 1A | Nearby | Locality listing |
| Xu 1 | Nearby | Locality listing for Xu 1 |
| Dadha village | Nearby village | Locality listing |
The question in the heading has no precise answer yet. No road is named as the line between Sigma 4 and the Ecotech blocks, and no published boundary exists. What the listings do show is distance. Ecotech 6 is about 2.42 km from the sector, within a short drive for plant staff but not a direct neighbor.
Sigma I is about 1.14 km away and Omicron I about 1.45 km. Sector 37 lies about 1.63 km off and Kasna about 2.46 km. These are straight-line figures between locality centers, useful for triangulation but not for drawing a boundary.
Dadha village appears among the nearby names, though no village abadi or inside landmark is known within Sigma 4.
Firm boundary information for Sigma 4 does not exist in public sources. Its neighbors come from property listings rather than a boundary map, and a GNIDA site plan is the reliable reference for its actual edges.
Sector Sigma 4 Greater Noida is a planned GNIDA residential sector that holds all three: authority-built simplex bungalows, group housing including a cooperative society, and a villa enclave. It is developed and occupied, and no village abadi is recorded inside it. The typology rests on a 2011 forum and listings.
All three, plus a cooperative. Sigma 4 is one of the more varied sectors in the Greek-letter grid, and this guide classes it as residential under GNIDA, the authority that planned and leased the land.
The oldest layer is authority housing. A 2011 residents' forum says GNIDA built simplex bungalows here, and it counts five parks among them. Like all planned-sector homes in Greater Noida, they stand on authority leasehold, so owners hold a lease rather than freehold title, and any resale needs a transfer memorandum from GNIDA.
Group housing came alongside. The same forum notes three group housing projects in Sigma IV by 2011. Listings name Royal Apartments, and a separate cooperative, BSNL Officers Sahkari Awas, built flats for its members.
Sigma 4 profile
Stellar Sigma Villas adds a third form. Listings describe it as a gated villa project on a few acres, sitting between the bungalow layout and the tower blocks in scale.
A property portal lists several ready-to-move projects, and the 2011 forum already describes built bungalows and occupied societies, so the sector is developed rather than emerging. No allotment year or scheme surfaced. No source places a village abadi inside.
The evidence is a residents' forum and a listing portal, not an authority document. The portal also tags one project to an unrelated Noida sector, which was excluded. GNIDA's records are the final word on which plots are authority-built and which were allotted to societies.
Sector Sigma 4 Greater Noida is a settled sector where gated villa clusters, cooperative apartment blocks and authority bungalows each run security in their own way. No police release or news report found points to crime or flooding here, so the arrangements of the specific building matter most.
Three security models share Sigma 4. A villa enclave of about 110 homes on 4.5 acres works behind one wall and gate. Cooperative and group housing blocks, including a society formed by public-sector employees, rely on a managing committee that hires guards and decides on cameras. The authority-built bungalows of roughly 200 to 220 square meters have no shared perimeter at all.
Villa enclave : About 110 villas on 4.5 acres behind a shared wall and gate.
Cooperative and group housing : Apartment blocks run by committees that hire guards and set visitor rules.
Authority bungalows : Houses of about 200 to 220 square meters with no common perimeter.
Police coverage : No station tied to Sigma 4 in police or news reports.
Reported incidents : None found at sector level.
Each model has trade-offs. A gated cluster controls entry well but can grow relaxed about visitors who sound familiar. Cooperative blocks depend on how active their committees are; some maintain logs and lighting carefully, others less so. Bungalow owners carry the full load themselves, though long tenure in these lanes means neighbors tend to notice unfamiliar vehicles.
No police release ties Sigma 4 to a named station, and a search for police news about the sector returned nothing specific. District-wide, the police reported in October 2025 that 630 female beat officers ran outreach sessions at 305 locations under Mission Shakti. That is a district figure, but it means a resident can ask the local station which woman beat officer covers the block.
The sector sits beside Dadha village, and the boundary road between the two is the stretch to watch after dark. A newcomer should ask the cooperative or enclave office how visitors are logged at night and whether the boundary road has working lights. This account rests on built form, not on reported events, which makes a visit and a few questions worth the time.
Depot, the eastern terminus of the NMRC Aqua Line, is the likely nearest operational station to Sector Sigma 4, but no source publishes the distance. Nearby Omicron 3 measures about 1.9 km from Depot in a straight line. GNIDA Office and Delta 1 are the other Aqua Line stops in range.
The planned 2.6 km Aqua Line extension from Depot to Boraki is the project closest to the Sigma and Omicron belt. The Union government approved it in July 2025, at an estimated cost of Rs 416.34 crore, with stations at Junpat and at a multimodal hub in Boraki. No source places either new station inside or beside Sigma 4, so its effect on this sector cannot be measured yet.
Its civil work was bundled into one contract with the Sector 142 to Botanical Garden extension. L&T was the lowest bidder at Rs 1,234 crore in August 2026, a news report said the work was awarded in September 2026, and the completion period is 1,096 days.
| Operational | Planned | |
|---|---|---|
| Line | Aqua Line (NMRC) | Aqua Line extension, Depot to Boraki |
| Nearest stop | Depot (likely); also GNIDA Office, Delta 1 | Junpat, Boraki |
| Distance from Sigma 4 | Not published | Not published |
| Status | Open since Jan. 25, 2019 | Approved July 2025; civil work reported awarded September 2026; about 2029 expected |
Today, Sigma 4 riders depend on the existing line. The sector adjoins Omicron 1A and Xu 1, and nearby Omicron sectors measure roughly 1.9 km to 2.8 km from Depot in a straight line. That range hints at the scale but does not stand in for Sigma 4.
Depot station, in Sector 34, has three platforms, and first trains leave it at 6 a.m. from Monday to Saturday. GNIDA Office, one stop toward Noida in Knowledge Park IV, and Delta 1, another stop on, give riders a choice depending on the block.
A 2011 forum post noted that Sigma IV faces the 130-meter road. No source lists e-rickshaw fares or feeder buses from the sector to any station.
Every distance tied to Sigma 4 is borrowed from a neighbor. The station names are a reasonable starting point; the kilometers are not published.
Sector Sigma 4 shares Pari Chowk and the Noida-Greater Noida Expressway with the rest of the Greek belt, and it sits about 0.98 km from Sigma II, a listing site says. Neighboring Xu 1 is about 4.4 km from Boraki station in a straight line, the nearest rail point.
Sigma 4 borders the Ecotech I Extension industrial area, Omicron 1A, Xu 1 and Dadha village, which makes it a natural base for people working shifts in the Ecotech belt. No source names its internal roads or entry points, though, and none gives a sector-level drive time.
Shift hours shape the options. Public airport e-buses from key Greater Noida points started in June 2026 with fares of Rs 10 to Rs 50, but they ran only from 8 a.m. to 8 p.m. at launch. The FlixBus coach to IGI Airport, announced from September 2025, runs around the clock from Pari Chowk for Rs 199. GNIDA approved a six-month pilot of 15 airport feeder e-buses in May 2026, without naming routes.
For intercity travel, UPSRTC runs services from its Kasna depot in Greater Noida. App cabs including Uber, Ola and Rapido serve Noida International Airport, which began commercial flights on June 15, 2026.
From neighboring Xu 1, straight-line, as a stand-in for Sigma 4:
The hub figures below come from Xu 1, which adjoins Sigma 4, and are straight-line distances from listing-site map pins. Sigma 4 itself has no published coordinates.
Treat the picture as rough. Only one neighbor distance is sourced for the sector, and every hub figure is borrowed from next door.
GNIDA-built simplex bungalows, a villa enclave and a handful of cooperative and group housing societies make up Sector Sigma 4 Greater Noida. Stellar Sigma Villas, BSNL Officers Sahkari Awas and Royal Apartments are the best-known names, all listed as ready to move.
Sigma 4 was already built and occupied by 2011, when a residents' forum described GNIDA simplex bungalows of 200 to 220 sq m and counted three group housing projects in the sector. A property portal now lists five ready-to-move projects.
Villas. Stellar Group's Stellar Sigma Villas has 110 villas on 4.5 acres, each a 5 BHK of 5,600 sq ft.
Cooperative housing. BSNL Officers Sahkari Awas offers 4 BHK homes of 2,450 sq ft. A listing site also tags a society called BSNLOSAS Mansarovar to Sigma 4; it may be the same cooperative under a shortened name.
Apartment societies. Royal Apartments, which a listing site calls Amrapali Royal Apartments, is listed as ready to move. Cassia Semia Estate carries the same tag with no further detail.
Location in question. Skyline Grand Forte, by Skyline Group, with 3 BHK units of 1,890 sq ft and 5 BHK units of 4,268 sq ft, is tagged to Sigma 4 on two portals, but one portal's own project description places it in Sector 140A. Its sector remains unsettled.
Authority houses. The GNIDA bungalows form the base of the sector, though no block names or totals are published.
| Name | Kind | Detail |
|---|---|---|
| Stellar Sigma Villas | Villa society | Stellar Group; 110 villas, 4.5 acres |
| BSNL Officers Sahkari Awas | Cooperative | 4 BHK, 2,450 sq ft |
| BSNLOSAS Mansarovar | Cooperative | Possibly the same as above |
| Royal Apartments | Society | Also listed as Amrapali Royal Apartments |
| Cassia Semia Estate | Society | Ready to move, no detail |
| Skyline Grand Forte | Society | Skyline Group; sector disputed |
| GNIDA bungalows | Authority houses | 200 to 220 sq m simplex |
How complete: fair; the named societies are known, but unit counts are missing for most and the bungalow stock is uncounted.
No. Neither school directories nor hospital listings place a facility inside Sector Sigma 4 Greater Noida. Millennium International School in Omicron I, a CBSE school to Class 8, is the nearest at about 2.09 km. For hospitals, GIMS near Kasna and Fortis Hospital Greater Noida offer 24-hour emergency care, with no distance published.
Children in Sigma 4 travel to Omicron I or Sigma II for school. Millennium International School, about 2.09 km away, teaches Pre Nursery to Class 8. Brain Tree Global School in Sigma II, about 2.44 km, runs Pre Nursery to Class 12.
Narayana e-Techno School and Scholars Home International School both have Omicron I addresses, each about 2.49 km away, and both teach Nursery to Class 12. Lotus World School in Sigma II, about 2.76 km out, ends at Class 10. Every school on the list follows CBSE.
| Schools | Hospitals |
|---|---|
| Millennium International School, Omicron I, to Class 8, about 2.09 km | GIMS, government, near Kasna, 24-hour emergency |
| Brain Tree Global School, Sigma II, to Class 12, about 2.44 km | Fortis Hospital Greater Noida, private, Surajpur, about 200 beds, NABH |
| Narayana e-Techno School, Omicron I, to Class 12, about 2.49 km | Ivory Hospital, private, Sector 36 (Rho I) |
| Scholars Home International School, Omicron I, to Class 12, about 2.49 km | CGHS dispensary, Phi III (central government beneficiaries) |
Three hospitals are named for the area, none with a distance from Sigma 4. Government Institute of Medical Sciences near Kasna is the state-run option, with 500 beds on its own site and about 300 by another count, plus 24-hour emergency and trauma care. Fortis Hospital Greater Noida is private, with about 200 beds and NABH accreditation. Ivory Hospital in Sector 36 is a private multi-specialty facility with no published beds.
Central government employees and pensioners can use the CGHS dispensary in Phi III. For emergencies, the district lists 108 for ambulance and 1800-419-2211 for medical help.
The school list is complete; hospital distances are not published.
On published evidence, thinly. Pal Market Kyampur, about 0.7 km from the center of Sector Sigma 4 Greater Noida, is the only named market nearby, and no mall, bank or fuel station has been tied to the sector with a name or a distance.
Sigma 4 is a built sector. A listing site shows several ready-to-move projects, and a 2011 residents' forum post already described bungalows and group housing here. The same site's nearby list for shopping, though, holds one entry: Pal Market Kyampur, in the Kyampur village area.
The site files that market under supermarkets. It names no bank, mall or petrol pump for the sector, and no pharmacy, milk booth or weekly bazaar appears in other sources.
The 2011 post grouped Sigma 4 with sectors marked by the absence of a proper shopping area. That is dated background; no newer source says whether shops have since opened inside the sector.
How complete this is: one market, and gaps everywhere else.
Four-bedroom flats in Sector Sigma 4 Greater Noida were listed at Rs 28,000 to Rs 50,000 a month in mid-October 2026, across two listings on one site and three on another. A fully furnished 3,200 sq ft unit in Kamat Vision Society asked Rs 1.50 lakh.
Large homes dominate the Sigma 4 rental pool. Besides the 4 BHK flats, a semi-furnished 4 BHK independent house was listed at Rs 50,000 a month in mid-October 2026. Skyline Grand Forte 4 BHK units ran from Rs 30,000 semi-furnished to Rs 50,000 plus Rs 4,000 fully furnished, and Royal Apartments 4 BHK units ran Rs 28,000 to Rs 32,000 on a property portal page updated October 4, 2026.
Three-bedroom flats asked Rs 22,000 to Rs 32,000 across two semi-furnished listings. Royal Apartments shows a 3 BHK at Rs 22,000 and Stellar Sigma one at Rs 32,000. An unfurnished 3 BHK independent house asked Rs 30,000.
Two-bedroom options are fewer. A semi-furnished flat in BSNLOSAS Mansarovar asked Rs 14,000 plus Rs 5,000 maintenance, marked negotiable. A 2 BHK independent house was listed at Rs 22,000 on one site, while the portal page dated October 4, 2026 showed three at Rs 25,000 to Rs 30,000.
The listing site states deposits in the area of Rs 28,000 to Rs 1,00,000 for society apartments and Rs 30,000 to Rs 1,00,000 for independent houses, with society maintenance of Rs 4,000 to Rs 5,000 a month.
| Configuration | Monthly rent | Source date |
|---|---|---|
| 2 BHK flat, BSNLOSAS Mansarovar | Rs 14,000 plus Rs 5,000 maintenance | Mid-October 2026 |
| 2 BHK independent house | Rs 22,000; Rs 25,000 to Rs 30,000 | Mid-October 2026; October 4, 2026 |
| 3 BHK flat | Rs 22,000 to Rs 32,000 | Mid-October 2026 |
| 3 BHK independent house | Rs 30,000 | Mid-October 2026 |
| 4 BHK flat | Rs 28,000 to Rs 50,000 | Mid-October 2026 |
| 4 BHK independent house | Rs 50,000 | Mid-October 2026 |
| 4+ BHK flat, Kamat Vision Society | Rs 1.50 lakh | Mid-October 2026 |
How firm the figures are: two listing sources from October 2026, about 16 listings in all, so each size rests on a handful of homes.
Villas and independent houses with 220 sq m built-up in Sector Sigma 4 Greater Noida were listed at Rs 3.12 crore, Rs 3.65 crore and Rs 3.7 crore on a property portal page updated Sept. 3, 2026. That page showed only seven properties for sale.
Villas account for 43 percent of sale supply on that portal, apartments 29 percent and independent houses 15 percent. With seven listings in total, each line below stands on one to three homes.
| Property type | Price | Source date |
|---|---|---|
| Villa or independent house, 220 sq m built-up | Rs 3.12 crore, Rs 3.65 crore, Rs 3.7 crore | Sept. 3, 2026 |
| Residential plot, 220 sq m | Rs 3.7 crore | Sept. 3, 2026 |
| Apartment, 3.5 BHK, Royal Apartments, 1,900 sq ft | Rs 1.6 crore | Sept. 3, 2026 |
| Apartment, 3.5 BHK, Stellar Sigma Villas, 2,150 sq ft | Rs 2.1 crore | Sept. 3, 2026 |
| Villa, 5 BHK, Stellar Sigma Villas | From Rs 3.92 crore | Mid-October 2026 |
Stellar Sigma Villas quotes a starting rate of Rs 7,000 per sq ft plus charges for its 5 BHK villas, while one listing there asks Rs 10 crore for 5,600 sq ft of carpet area.
Another listing site averages villas in the sector at Rs 25,714 per sq ft, but that number rests on two Austonia Estate listings seen in mid-October 2026: Rs 5 crore for 1,500 sq ft and Rs 4 crore for 2,000 sq ft.
Several projects, including BSNL Officers Sahkari Awas, Skyline The Grand Forte, Cassia Semia Estate and Royal Apartments, show prices on request at the project level. A further portal gives an undated all-property average of Rs 6.11 K per sq ft.
Official rates are kept separate from these asks. Gautam Buddh Nagar's circle rate list effective Aug. 1, 2019, which remains in force, places Sigma 4 in Zone C: Rs 26,000 per sq m of plot area for a residential plot, Rs 26,500 per sq m of covered area for a group housing flat and Rs 44,250 per sq m for a commercial plot. These rates set the stamp duty minimum and do not reflect market prices.
On firmness, this is a thin market: seven dated listings from early September 2026, a two-listing villa average and an undated portal figure.
Households that want a house or villa rather than a tower flat will find Sector Sigma 4 Greater Noida a strong match, since it is built around authority bungalows and ready villa projects. Singles on a tight budget and parents wanting a school inside the sector should look elsewhere.
Sigma 4 is a settled sector. The authority built simplex bungalows here, and the main projects, including Stellar Sigma Villas, BSNL Officers Sahkari Awas, Royal Apartments and Skyline Grand Forte, are listed as ready to move.
Families wanting space are well served. Stellar Sigma Villas offers large five-bedroom villas, and a three-bedroom independent house was listed for Rs 30,000 a month in October 2026.
Renters who prefer a smaller society also fit. A two-bedroom flat at BSNLOSAS Mansarovar was listed at Rs 14,000 a month plus Rs 5,000 maintenance, a quieter alternative to the large tower clusters nearby.
The market is small, though. Only about seven listings appeared on one property portal in early October 2026, so expect to wait for the right home rather than pick from many.
No school is listed inside the sector, so the school run means a drive. The nearest listed metro station is Depot on the Aqua Line, with no confirmed distance, so most residents will rely on a car. Retirees who no longer drive should weigh that carefully before moving in.
| Suits | Look elsewhere |
|---|---|
| Families wanting a villa or bungalow | Singles seeking a cheap one-bedroom |
| Renters preferring a small society | Parents wanting a school inside the sector |
| Buyers wanting a ready home | Anyone needing a wide choice of listings |
The short version: low-rise, ready and spacious, but small in supply and car-dependent.
| Property Type | Average Price |
|---|---|
| Independent House : | ₹19,769 Sqft |
| Villa : | ₹20,729 Sqft |

Yes. GNIDA's office order of July 8, 2018 on additional compensation names the BHS06 housing scheme in both Sigma-3 and Sigma-4, along with Amaltash 1, 2 and 3. The order's listing shows no amount, and whether dues remain is not confirmed. Before buying a resale Authority house in Sigma 4, ask the seller for written confirmation from GNIDA that no compensation dues are pending.
No, tenders were still pending in May 2026. A May 3, 2026 report said NMRC expected to float construction tenders the following month for the 2.6 km elevated extension from Depot to the Boraki Multi Modal Transport Hub. The Union Government approved the line in July 2025 at an estimated Rs 416 crore, with new stations at Junpat and Boraki. Check NMRC for award and work status.
