Random Cardiff Address Generator
A random Cardiff address generator produces fictional postal addresses that use real CARDIFF postcode districts (CF), a real preserved county (South Glamorgan) and Royal Mail address formatting, for use as software test data.
Generate realistic random Cardiff addresses for software testing. Each address combines a real CARDIFF postcode district (CF3, CF5, CF10, CF11, CF14, CF23 and 1 more) with a British street name, the CARDIFF post town and the preserved county of South Glamorgan, laid out to Royal Mail conventions. Telephone numbers use the 029 2018 0xxx range that Ofcom reserves for drama, so no generated number can reach a real subscriber.

Postal notes
- CF10 1EP is a widely used example of a Cardiff city-centre postcode.
- Cardiff is the capital of Wales; Welsh and English street names appear side by side, and both spellings are valid on addressed mail.
- The 029 dialling code uses eight-digit local numbers beginning 20, so "029 2018 0000" is dialled as 029 followed by eight digits.

Frequently asked questions
- Are these real Cardiff addresses?
No. The CARDIFF post town, its 7 postcode districts and the South Glamorgan preserved county are genuine, but the house numbers, street pairings and names are fictional and the last three characters of each postcode are generated. The results are structurally valid test data, not deliverable addresses.
- Which postcode districts does Cardiff use?
Cardiff is served by 7 districts in the CF postcode area: CF3, CF5, CF10, CF11, CF14, CF23, CF24.
- What is the dialling code for Cardiff?
Cardiff uses the 029 dialling code. Generated numbers are not built on live 029 subscriber ranges: every number comes from the 029 2018 0xxx block that Ofcom reserves for drama and fiction, so it can never dial a real person.
- Is a county line required on a Cardiff address?
No. Royal Mail has not required a county line since 1996 - the post town (CARDIFF) and a correct postcode are sufficient. The generator includes South Glamorgan as an optional line because many address forms and legacy databases still expect one.
- Can I generate Cardiff addresses through the API?
Yes. Call GET /api/v1/addresses/random?location=cardiff&count=25 for JSON, or add &format=csv, &format=sql or &format=xml for bulk export. No API key is required.
