COMMON QUESTIONS
Frequently asked questions
Is the result the Royal Mail post town?
Not necessarily. Royal Mail PAF post-town data is not provided by the open Postcodes.io response, so this tool clearly shows open built-up-area and administrative place fields instead.
Why can the built-up area differ from the council?
Built-up areas describe settlements, while administrative districts describe local-government geography.
Can I search a postcode district only?
This lookup expects a full UK postcode.
Where does the place data come from?
The live lookup uses Postcodes.io open postcode geography data.
