What Is the Anambra State Postal Code? 420001–435115 Complete Guide for 2026

Anambra State does not use one single postal code. Instead, each town or delivery area carries its own six-digit number, and the numbers commonly listed for the state run from 420001 to 435115.
Knowing how these numbers are grouped makes it much easier to find the right one for your address, whether you are filling an online form, booking a courier or sending documents.
This guide explains the range and shows how to use it with confidence.
The Anambra Postal Code Range
Postal codes for Anambra State are commonly listed from 420001 to 435115. Awka, the state capital, sits near the start of the range with 420001, while the numbers for towns in the south and west run higher.
How the Opening Digits Group Areas
The first three digits point to a wider postal area. In published lists, 421 appears for Njikoka towns such as Abagana and Enugwu-Ukwu, and 423 for Orumba North and Orumba South towns such as Nanka and Umunze. The 431 group covers Ihiala and Ogbaru communities, 433 covers Oyi towns such as Nteje and Awkuzu, and 434 covers Idemili South towns such as Ojoto and Nnobi. Nnewi and its neighbours in Nnewi South appear under 435.
Finding the Code for Your Town
Start with the name of your town and its local government area. Match it with the opening digits above, then confirm the full six-digit number at a post office or from an official letter sent to your address. Published lists sometimes differ on the last digits, so confirmation matters.
Writing a Complete Address
Write the recipient’s name, then the house number and street, then the town, local government area, Anambra State and the postal code.
Use clear capitals on parcels and keep a second copy of the address inside the package.
Tips for Smooth Deliveries
Add a working phone number and a landmark, such as a church, school or market. Save your confirmed code in your phone notes so every form you fill from now on is quick and correct.
Postal details can change over time, so check again before sending important documents.
Business owners can print the town name and confirmed code on receipts and delivery notes, which helps customers in other states send returns and enquiries to the right place.
