Frequently asked questions
How accurate are these codes?
The district-capital and major-town codes shown are well established. Sri Lanka uses 5-digit postal codes, and exact codes for individual streets, suburbs or rural areas can vary, so for those use Sri Lanka Post's official finder.
Is anything uploaded?
No. The list is built into the page and searched in your browser, so it works offline with nothing uploaded.
How do I copy a code?
Just tap the code next to a town and it is copied to your clipboard.
Why is my small village not listed?
This is a quick reference for major towns and district capitals. For smaller or rural locations, check Sri Lanka Post at slpost.gov.lk for the precise code.
What is the correct address format?
Write the recipient and street, then the city and its postal code, then SRI LANKA in capitals on the last line for international mail.
