UK dialling codes by town (A–Z)

How to use this index

This page maps UK towns to their geographic dialling codes. The 594 entries below resolve to 594 distinct 01/02 codes — the two figures differ because a handful of large codes carry more than one town label (for example a single metropolitan code can serve several named districts). Letters are not evenly populated either: B alone accounts for 66 towns, the largest single bucket in the A–Z. Use the alphabetical jump bar to go straight to a letter, then tap a town to open its dedicated page.

A dialling code anchors on a principal town but reaches across the surrounding charging area, so the boundary of an 01/02 code is wider than the town centre alone. The mapping is also not permanently fixed to a person: under UK number portability a customer keeps their existing number — and therefore the town code attached to it — after switching provider, and a ported number stays linked to the original code even after the holder moves elsewhere in the country. That is why a code in this index identifies where a number was first issued, not necessarily where the person answering it lives today.

To look up a specific number rather than browse by town, open the town’s page from the list below and paste the full number into the reverse-lookup form there. You’ll see the Ofcom Range Holder that the number’s block was allocated to, the allocation status, and a live internet check for public reports about that exact number — far more telling than the dialling code on its own. Codes are grouped into 60 UK regions below the A–Z if you’d rather explore geographically.
