Essex UK dialling codes

Essex is served by 11 geographic dialling codes in Ofcom’s National Telephone Numbering Plan, anchored on principal towns including Basildon, Braintree, Brentwood, Chelmsford, Clacton-on-Sea. Every entry below is a real, currently-allocated 01 or 02 code — tap a card to open the per-town page, where you’ll find the full table of Ofcom-allocated number ranges for that code, the Range Holder behind each block, and a reverse-lookup form for identifying any specific Essex caller. The data refreshes weekly from the public Ofcom Numbering Data feed, so allocations are at most seven days old.
