I once had a customer from a small village near Siwan who ordered a product, but I entered the wrong PIN code – just one digit off. The parcel reached a different district, and the customer had to travel almost 40 kilometers to collect it. That day I realized that in a state like Bihar, where villages outnumber cities, having the correct PIN code is not a luxury; it is a necessity. Over the years, I have compiled this district‑wise guide to make sure you never make the same mistake.
Bihar’s PIN code zone – what the first digits mean
Bihar falls under the 8xxxxx PIN code zone (eastern India). The first digit is always 8. Here is a quick breakdown:
- 80xxxx – Patna, Nalanda, Bhojpur, Buxar, Rohtas (Western part of Bihar)
- 81xxxx – Bhagalpur, Banka, Munger, Jamui (Eastern part)
- 82xxxx – Gaya, Nawada, Aurangabad, Jehanabad (Southern part)
- 83xxxx – Darbhanga, Madhubani, Samastipur (Northern part)
- 84xxxx – Muzaffarpur, Vaishali, Sitamarhi, East Champaran, West Champaran (North‑western part)
- 85xxxx – Purnia, Katihar, Kishanganj, Araria (Eastern & Seemanchal region)
Once you remember this pattern, finding a PIN code becomes far easier – even if you only have the district name.
Patna – the heartbeat of Bihar (PIN codes you will use daily)
Patna is divided into several postal zones. The main PIN code for Patna GPO is 800001 (located near Gandhi Maidan). Here are the most commonly used Patna PIN codes:
| Area / Locality | PIN Code | Post Office |
|---|---|---|
| Patna GPO / Gandhi Maidan / Dak Bungalow Crossing | 800001 | GPO |
| Patna City / Chowk / Gulzarbagh | 800008 | Patna City SO |
| Rajendra Nagar | 800016 | Rajendra Nagar SO |
| Kankarbagh | 800020 | Kankarbagh SO |
| Pataliputra Colony / Bailey Road | 800023 | Pataliputra SO |
| Boring Road / Sri Krishna Puri | 800013 | Boring Road SO |
| Frazer Road / Exhibition Road | 800001 | Under GPO |
| Patliputra Nagar / Indrapuri | 800024 | Patliputra Nagar SO |
| Danapur Cantonment | 801503 | Danapur Cantt SO |
| Khagaul / Phulwari Sharif | 801503 | Same as Danapur |
If you are sending something to any of these areas, double‑check the PIN code. Patna GPO area (800001) is huge, but many lanes have their own sub‑post offices.
Gaya – the land of salvation
Gaya is famous for the Mahabodhi Temple, but for courier purposes, you need these PIN codes:
- Gaya GPO – 823001 (covers most of the city)
- Bodh Gaya – 824231 (many pilgrims send prasad back home)
- Manpur – 823003 (important for industrial deliveries)
- Tekari – 824236 (covers a large rural area)
Bhagalpur and Munger – the silk city and the old fortress
These two districts have high e‑commerce activity because of the silk industry and engineering colleges.
- Bhagalpur GPO – 812001 (most of the city)
- Munger GPO – 811201
- Jamalpur – 811214 (important for railway colony deliveries)
- Sultanganj – 813213 (many devotee parcels)
Muzaffarpur, Darbhanga, and the Mithila region
This is the cultural heart of Bihar. The PIN codes are fairly straightforward:
- Muzaffarpur GPO – 842001
- Darbhanga GPO – 846001
- Samastipur – 848101
- Madhubani – 847211
- Sitamarhi – 843302
Purnia, Katihar, and Seemanchal region
These districts are close to the Nepal border and West Bengal. The PIN codes here start with 85:
- Purnia GPO – 854301
- Katihar GPO – 854105
- Kishanganj – 855107
- Araria – 854311
- Forbesganj – 854318

Common mistakes people make with Bihar PIN codes
Based on real‑world courier returns and my own experience, here are the top 5 errors:
- Using 800001 for any address in Patna – it works only for the GPO area.
- Confusing 800008 (Patna City) with 801503 (Danapur) – both have completely different delivery zones.
- Writing 812001 for a village near Bhagalpur – many villages have their own sub‑PIN codes under the 812xxx range. Always use the exact one.
- Using old PIN codes that were changed by India Post (very rare but check before sending heavy shipments).
- Sending a parcel to a "Block" without writing the district name – the PIN code alone may confuse the sorting office.
