Watch the leading zero
Some Sri Lanka postal codes begin with a zero, such as 00100. Spreadsheets and some web forms silently drop it, turning 00100 into 100 — which is either a different place or not a valid code at all. Format the column as text before pasting codes into a spreadsheet.
How an address is written in Sri Lanka
This is the order Sri Lanka's postal service expects. Square brackets mark what you replace.
[Recipient name]
[Street address]
[City]
[Postal code (20000)]
SRI LANKA
A postal code is optional in Sri Lanka addresses — mail is deliverable without one, though including it speeds up sorting.
Look up a specific address
For the code covering one particular street or building, Sri Lanka's postal service publishes an official finder: www.slpost.gov.lk. It is authoritative and kept current, which third-party copies often are not.
