Random London addresses for mockups

This London dummy address page is for product, design, and QA work. Pick a count, generate, then copy a single card or export the whole set. The map and typeahead only snap to places we actually cover, not every hamlet on earth.

UK addresses put the building number or name first, then the street. A locality line is common outside city centres. Post towns are written in capitals on envelopes; we keep title case for UI. The postcode follows outward code + inward code (e.g. SW1A 1AA, M1 1AE, EH1 1YZ). A typical example looks like EC1A 1BB. We invent the digits around a prefix tied to the selected city so the shape is familiar in forms, without being a known delivery point.

Treat every row as non-deliverable test data. For testing and design only. These addresses are synthetic and format-correct, not real homes, not real people, and not deliverable. Do not use them for shipping, billing, identity, or any legal purpose. Optional coordinates sit near London only so a map pin has somewhere to land.

Exports are UTF-8 CSV and pretty-printed JSON, ready for Excel, Figma tables, or a fixtures file. Mention of CSV and JSON is the same dataset you see on this page. Generate up to 500 London dummy addresses per click.
