Islamabad, the capital city of Pakistan, uses postal codes (also called PIN codes or ZIP codes) issued by Pakistan Post under the federal postal system. Islamabad’s postal codes follow a structured format reflecting the city’s planned sector-based layout. This comprehensive guide covers all Islamabad postal codes by sector and zone, explains how Pakistan Post’s coding system works, and provides guidance on using postal codes correctly for mail delivery, online forms, and official government applications.
Islamabad Capital Territory: Overview and Postal Zones
Islamabad Capital Territory (ICT) is a federally administered area carved out of Punjab. Unlike other Pakistani cities that grew organically, Islamabad was purpose-built as the national capital following a 1959 governmental decision, with Greek architect Doxiadis Associates designing the master plan. The city is divided into alphabetically named sectors (F, G, H, I, E, D) each subdivided by numbered blocks. This systematic layout makes Islamabad’s postal code system more structured than older cities like Karachi or Lahore.
Pakistan Post assigns a unique 5-digit postal code to each sector, zone, and locality within Islamabad. The main Islamabad Head Post Office is located in Sector G-6/2 and handles sorting for the entire capital territory. Rawalpindi, the adjacent twin city, has separate postal codes beginning with 46000 series. When addressing mail to Islamabad, using the correct sector-specific postal code ensures faster delivery and reduces misrouting between the many residential and commercial areas.

The master postal code for all Islamabad addresses when you are unsure of the specific sector code is 44000. Pakistan Post’s Islamabad sorting center can route mail with the 44000 code to the appropriate delivery office based on the written street address. However, using the specific sector code accelerates delivery by routing directly to the correct sub-post office without additional sorting steps.
How Pakistan Post’s Postal Code System Works
Pakistan uses a 5-digit postal code system maintained by Pakistan Post (a government entity under the Ministry of Communications). The first two digits identify the region or city: 44xxx for Islamabad, 46xxx for Rawalpindi, 54xxx for Lahore, 75xxx for Karachi. The remaining three digits identify the specific post office or delivery area within that region. Pakistan Post periodically updates postal codes as new residential schemes, housing authorities, and localities are recognized — the latest official codes are always available at Pakistan Post main offices and on the Pakistan Post official website.
When filling government forms, passport applications, CNIC addresses, or courier service forms in Pakistan, the postal code field refers to this 5-digit Pakistan Post code. International courier services like DHL, FedEx, and TCS use the same postal codes for Pakistani destinations. For online shopping (Daraz, Bykea, Foodpanda delivery addresses), the postal code helps auto-populate city and area information and ensures delivery to the correct zone within Islamabad’s large geographic spread.
Islamabad vs Rawalpindi Postal Codes: Key Differences
Islamabad and Rawalpindi are physically adjacent cities but are administered separately — Islamabad as a federal capital territory and Rawalpindi as part of Punjab province. This distinction means they have completely separate postal code series. Islamabad postal codes begin with 44xxx (e.g., 44000 for the city center). Rawalpindi postal codes begin with 46xxx (e.g., 46000 for Rawalpindi Saddar, 46300 for Wah Cantt). When addressing mail, ensure you use the correct city’s code. A Rawalpindi address sent with an Islamabad postal code, or vice versa, will be misrouted to the wrong sorting facility and cause significant delivery delays.
Border areas between Islamabad and Rawalpindi — including areas along GT Road where both cities’ administrative boundaries overlap — sometimes cause confusion. In these cases, the street address and city name are the decisive factors. Pakistan Post delivery staff know the precise administrative boundary. If your address is genuinely in a border zone, use 44000 (Islamabad) if you believe your area falls within ICT boundaries, or confirm with your nearest post office branch.
New Islamabad Sectors and Housing Schemes Postal Codes
Islamabad has expanded significantly since the original CDA master plan. New sectors (G-13, G-14, G-15, G-16, F-14, F-15, B-17) and major housing schemes (Bahria Town, DHA Phase 2 Extension, Capital Smart City, Blue World City) have been developed in areas originally outside the planned city boundary. These newer developments may use the generic 44000 Islamabad code or have been assigned specific codes as they formalized. For the most accurate postal code for new housing schemes, contact Pakistan Post’s Islamabad General Post Office at the G-6/2 location or use the online postal code lookup on the Pakistan Post website.
International mail and courier deliveries to Islamabad housing schemes should always include the full street address, block number, plot number, phase number (for housing schemes), and the city name “Islamabad” in addition to the postal code. International postal services rely more heavily on complete written addresses than on postal codes for Pakistan deliveries because the 5-digit code system, while official, is not universally programmed into all international mail routing databases.
Frequently Asked Questions: Islamabad Postal Code
Q: What is the postal code for Islamabad for international forms?
A: Use 44000 as the general Islamabad postal code for international forms. If the form requires more specificity, use the sector-specific code from the table above. Always include “Islamabad, Pakistan” after the postal code for international addressing.
Q: Is the Islamabad postal code the same as the ZIP code?
A: In Pakistan, “postal code,” “PIN code,” and “ZIP code” are used interchangeably. All three terms refer to the same 5-digit Pakistan Post code. The term “ZIP code” is technically American but is commonly understood in Pakistani contexts, especially in online forms. The Islamabad postal/ZIP code is 44000 for general use.
Q: What postal code should I use for the Federal Government Employees Housing Foundation (FGEHF) areas?
A: FGEHF schemes in and around Islamabad typically use the 44000 Islamabad general code. For more precise delivery, include the complete address with sector, block, and street number. Contact Pakistan Post’s main Islamabad office (G-6/2) to confirm whether your specific FGEHF location has been assigned a distinct sub-code.
Q: How do I find postal codes for areas not listed in this guide?
A: Visit the Pakistan Post official website and use the postal code lookup tool, or call Pakistan Post’s general enquiry number. You can also visit any post office branch in Islamabad and ask the postmaster for the code for your specific area. Pakistan Post branches are present in virtually every sector and major commercial area of the city.
Islamabad Address Format: How to Write Correctly for Mail and Courier
Writing a correct Islamabad address requires understanding the CDA sector-block system. A standard Islamabad residential address follows this format: House Number, Street Number, Block/Sub-sector, Sector, City (Islamabad), Postal Code. For example: House 45, Street 12, G-9/4, Islamabad, 44200. Commercial addresses follow a similar pattern: Shop/Office Number, Plaza Name, Blue Area (or specific market name), Islamabad, 44050 for the commercial zone.
For Pakistan Post registered mail and parcels, write the address on the envelope clearly with the sector designation followed by the block number. Pakistan Post delivery staff know the sector-block geography well and can deliver accurately with just the sector code and postal code, but including the full block and street details eliminates any ambiguity. For courier services, the full detailed address reduces the risk of misdelivery in adjacent sectors that share similar street numbering schemes.
Islamabad CDA Sectors: Complete Zone Reference
Islamabad’s Capital Development Authority (CDA) divides the city into lettered sectors (A through I) arranged along the Margalla Hills foothills. Each sector is divided into four quadrants designated by numbers 1 through 4 appended after a slash (e.g., G-6/1, G-6/2, G-6/3, G-6/4). Residential sectors include F, G, I, and H series. The E sector houses most diplomatic missions and the diplomatic enclave. Commercial zones are concentrated in the Blue Area (G-5 to F-7 along Jinnah Avenue), the Jinnah Super Market (F-7 Markaz), and the Aabpara market complex (G-6).
As Islamabad expands beyond the original CDA master plan boundary, newer sectors are being developed by the CDA and various housing authorities. Sectors like G-13, G-14, G-15, B-17 (Multi Gardens), F-14, and F-15 are all in various stages of development. These sectors generally use the 44000 general Islamabad postal code until Pakistan Post formalizes specific sub-codes for each. The Islamabad Capital Territory Administration (ICTA) manages the expanded territory including the outer areas like Attock Khurd, Sangjani, Tarlai, and the motorway corridor.
Government Offices in Islamabad: Key Postal Addresses
Islamabad hosts Pakistan’s federal government institutions. Key government addresses: Parliament House is located on Constitution Avenue, Islamabad, postal code 44000. Prime Minister’s Office (PM Secretariat) is on Constitution Avenue, 44000. The Supreme Court of Pakistan is at Constitution Avenue, 44000. The FBR (Federal Board of Revenue) headquarters is located in Sector G-5, postal code 44050. NADRA Headquarters is in Mauve Area, G-7/1, 44100. PTA (Pakistan Telecommunication Authority) is in Sector F-5/1, 44000. These postal codes are relevant for anyone sending official correspondence, legal documents, or formal complaints to federal government institutions.
For sending documents to government offices, Pakistan Post’s registered mail service provides delivery confirmation and is preferred for legal and official correspondence. Retain the postal receipt as proof of dispatch. Most federal government offices also accept courier deliveries through TCS or similar services, which provide superior tracking and delivery confirmation. When in doubt about the correct postal code for a specific government department, call Pakistan Post’s general enquiry or check the receiving institution’s official website for their mailing address.
E-Commerce and Online Shopping Delivery to Islamabad
Islamabad is one of the most e-commerce-active cities in Pakistan. Platforms like Daraz, Foodpanda, bykea, and Careem deliver across the city. For Daraz deliveries, entering your Islamabad address requires selecting “Islamabad” as the city, then choosing your area/sector from the dropdown. The postal code field should be populated as 44000 (general) or the specific sector code if available in Daraz’s location database. Daraz offers same-day delivery to most G and F sectors in Islamabad and next-day delivery to outer areas including new housing schemes.
International e-commerce platforms including Amazon (through third-party shipping forwarding services), AliExpress, and Shein deliver to Islamabad addresses. For AliExpress, enter the full address including sector and block, the city as “Islamabad,” the country as “Pakistan,” and the postal code as 44000. International parcels enter Pakistan through Islamabad’s National Logistics Cell (NLC) or Pakistan Customs at the Islamabad Dry Port in Rawalpindi — clearance typically takes 2–10 working days after arrival. TCS, FedEx, and DHL provide premium international delivery to Islamabad with customs clearance support.
Rawalpindi Postal Codes: Adjacent City Quick Reference
Because Islamabad and Rawalpindi are physically joined cities, it is useful to know Rawalpindi’s postal codes to avoid confusion. Rawalpindi’s main postal code is 46000 (Rawalpindi Saddar). Other Rawalpindi area codes include: Westridge 46100, Chaklala Scheme 46200, Bahria Town Rawalpindi/Islamabad 46220, Wah Cantt 47040, Taxila 47080, Gujar Khan 47850, and Attock 43600. Mail addressed to Rawalpindi areas must use 46xxx codes, not Islamabad’s 44xxx codes, even though both cities share a continuous urban footprint along their administrative boundary near Faizabad interchange.
When addresses reference “Pindi” — the common shorthand for Rawalpindi — always use 46xxx postal codes. Residents of areas like Saddar, Raja Bazar, Lal Kurti, and Cantt (Rawalpindi Cantonment) are all in Rawalpindi, not Islamabad, and use Rawalpindi postal codes. Only the ICT administrative boundary definitively determines whether a location uses Islamabad or Rawalpindi postal codes — when in doubt, check with your local post office counter.
