Frequently asked questions
Is the list official?
No. It is an attributed GeoNames snapshot. Only selected records were checked with Sri Lanka Post.
Why is my town missing?
The source is incomplete, especially in northern districts. A missing result is not proof that the postcode does not exist.
Why do codes repeat?
One code can have multiple locality names or spelling variants in the original data.
Check the stated data sources and assumptions before relying on a result.
