Random Northern Ireland Address Generator
A random Northern Ireland address generator produces fictional postal addresses formatted to Royal Mail conventions, using real Northern Ireland post towns and postcode districts, for use as software test data.
The whole of Northern Ireland is covered by a single postcode area, BT, running from BT1 in central Belfast to BT94. Postal addresses commonly still reference the six traditional counties. This generator draws on 21 real postcode districts across 4 post towns in Northern Ireland, formats every result to Royal Mail "Clear Addressing" rules and pairs it with a telephone number from an Ofcom range reserved for fiction. Every address is synthetic and is intended for QA automation, form validation and database seeding.

- Which postcode areas cover Northern Ireland?
This generator covers 1 postcode areas in Northern Ireland: BT. Together they contain the 21 postcode districts used by the generator.
- What is a traditional county?
Northern Ireland has 11 local government districts, but addresses commonly still use the six traditional counties: Antrim, Armagh, Down, Fermanagh, Londonderry and Tyrone.
- Can I filter the API to Northern Ireland only?
Yes. Call GET /api/v1/addresses/random?country=Northern%20Ireland to restrict generation to Northern Ireland, or pass a specific post town with ?location=<slug>.
