What Is Assam PIN Code?
As of 2026, India Post still uses the 6-digit PIN code system it introduced way back in 1972 to keep mail moving smoothly across the country.
Quick Fix Summary: Need a PIN code for Assam? Start with 78. For Dibrugarh district (226 post offices), use 786xxx format. Guwahati GPO is 781001. Airport is 781015. IIT Guwahati is 781039.
What’s the deal with Assam PIN codes?
The PIN code system splits India into 9 regions. Assam lands in region 7, which is why every Assam PIN starts with 78. The first two digits point to the sorting district (usually the biggest city there), and the last three zero in on a specific post office. Take Dibrugarh district—it’s got 226 post offices as of 2026 and uses codes in the 786xx range.
How do I actually find an Assam PIN code?
- Pin down the city or district: Figure out if you need the PIN for Guwahati, Dibrugarh, Silchar, or somewhere else in Assam.
- Grab the sorting district prefix: Around Guwahati, the main sorting district is 781. Over in Dibrugarh, it’s 786.
- Track down the exact post office:
- Guwahati General Post Office (GPO): 781001
- Guwahati Airport Post Office: 781015
- IIT Guwahati Campus Post Office: 781039
- Dibrugarh Head Post Office: 786001
- Confirm it online: Head to the India Post official website and run a quick “PIN Code Search” to lock in the right 6-digit code for your spot.
What if that didn’t work?
- Try a postal directory: Grab the latest “Postal Codes of India” PDF from India Post’s Pin Code Directory (updated as of 2025).
- Ring up the local post office: Call or swing by the nearest post office in Assam. Dibrugarh GPO (0373-2320111), for example, can confirm codes in its area.
- Ask courier services: FedEx, DHL, and Blue Dart usually have PIN codes pre-loaded in their systems. Use their online calculators to double-check.
How can I stop using the wrong PIN code?
Always triple-check the exact locality and district. Tiny towns can share names across different districts—“Nalbari” could mean Nalbari district or a neighborhood in another area. Spell it out fully: “Nalbari, Assam.”
Update your address every time you move. Sending something to IIT Guwahati? Use 781039 and write “IIT Guwahati Campus Post Office” as the branch.
If you’re sending bulk mail, download India Post’s official PIN list every year—new post offices pop up all the time (Assam added 12 between 2024 and 2026).
