Why the last three digits matter
Every postal code in the Awka area begins with 420. The last three digits tell the sorting team the exact district. Ezinato ends in 102, Isiagu ends in 103 and Umuawulu ends in 104. If you mix them up, the parcel may arrive late or go to the wrong town.
Common problems
Type the six digits without spaces, dashes or letters.
Use the code of the district where the house is built. When unsure, ask a neighbour or the nearest post office.
Send a landmark and keep your phone on. Name a school, church, shop or junction near the gate.
Good habits
- Save the full address in your notes and copy it every time.
- Write the town name in full, not in short form.
- Check the code again before you pay for an order.
Mistakes to avoid
- Writing Ezinato on the label while using the Isiagu code.

- Typing the code with a space in the middle.
- Forgetting a landmark for a new road.
