Served Up Limited in Cambridge

About Served Up Limited’s Cambridge allocation

When Served Up Limited is the range holder for +44 1223 it means Ofcom recorded Served Up Limited as the provider entitled to issue numbers from these blocks when they were first allocated under the UK National Telephone Numbering Plan. 12 Cambridge-facing blocks sit against Served Up Limited in the current Ofcom snapshot, each of which can carry up to ten thousand individual digits available for assignment to end customers.

Cambridge’s Cambridgeshire telecoms estate is shaped by Cambridge's catchment of roughly 145,000 residents: a dense urban exchange typically hosts allocations from several national operators in parallel, which is why you see Served Up Limited’s blocks alongside other range holders on the same 01223 code. Local switching capacity, historic Openreach exchange footprints, and Served Up Limited’s wholesale routing arrangements all influence which blocks land in Cambridge rather than elsewhere on the national plan.

Treat this allocation as a starting point, not a verdict on any specific caller. UK numbers are portable, so the current carrier on a given 01223 digit string may differ from the range holder shown — read Range Holder vs current provider for the distinction, and How Ofcom allocates UK phone numbers for the wider context behind the table below.
