Generate real-format random Wales (GB) addresses with streets, cities, postcodes, phones and identity profiles for free. Wales has over 600 castles — the most per square mile in Europe.
Safe Mock Data Guarantee:
All synthetic numbers maintain authentic field lengths but are mathematically guaranteed to fail live verification. Emails and phone numbers cannot receive messages, preventing fraud and meeting developer compliance standards.
Safety notice: all data is randomly generated in your browser as test samples and does not represent any real person. This data must not be used for identity verification, opening accounts, or real payments.
Where to Apply These Test Records in Workflows

Decoding UK Postcodes and Regional Dialing Rules
Addresses in Wales follow the standard United Kingdom layout: house number first, street name second, then a city such as Cardiff, Swansea, Newport, and finally a postcode in the SW1A 1AA shape, with the country line only for international mail. Postcode prefixes and area codes (029、01792、01633、01248) are allocated to Wales specifically — mismatching the prefix across regions is the most common cause of form rejections.

Ready-to-Use Sample Addresses for Cardiff and Swansea
Two fixed samples below follow the United Kingdom writing convention for Wales — field order, postcode length and area codes all match the real structure, so you can copy them and swap the digits:
Example 1:
9812 State Rd
Bangor LL28 4SN
United Kingdom
Example 2:
414 Park Dr, Apt 121
Wrexham LL64 3CN
United Kingdom
House numbers and street names are random, but the city, region and postcode prefix come from real Wales ranges, so format validation passes — that does not make them real residents.

Frequently Asked Questions on Welsh Address Fields
What is the VAT rate in Wales?
A flat nationwide standard rate independent of region; some food and books use reduced rates. The rate is set nationally, so Wales is no different from any other region — you do not need to pick a postcode for tax reasons, and the postcode prefix format is what actually matters.
Which area codes does Wales use?
Relevant area codes include 029、01792、01633、01248, inside country code +1. Generated numbers use these prefixes in the correct local grouping but will not connect.
Will a Wales address pass form validation?
It passes format validation: city, region and postcode prefix all come from real Wales ranges (SW1A 1AA). Format checks (regex, digit count, dropdown values) will pass; strict third-party address verification APIs may not resolve a street.
Are the generated Wales addresses real?
No. The format follows United Kingdom conventions, but the house number, street and residents are randomly assembled sample data for development and form-filling only.
Can I generate Wales addresses in bulk?
Yes. On the homepage switch to the "Batch" tab, select United Kingdom and Wales, then export hundreds of addresses as CSV or JSON at once.
Is my data uploaded to a server?
No. Everything is generated locally in your browser, nothing is sent anywhere, and it is cleared when you close the page.
