WAVECREST NETWORKS LIMITED in Chelmsford

About WAVECREST NETWORKS LIMITED’s Chelmsford allocation

When WAVECREST NETWORKS LIMITED is the range holder for +44 1245 it means Ofcom recorded WAVECREST NETWORKS LIMITED as the provider entitled to issue numbers from these blocks when they were first allocated under the UK National Telephone Numbering Plan. 6 Chelmsford-facing blocks sit against WAVECREST NETWORKS LIMITED in the current Ofcom snapshot, each of which can carry up to ten thousand individual digits available for assignment to end customers.

Chelmsford’s Essex telecoms estate is shaped by Chelmsford's residential and business catchment: a dense urban exchange typically hosts allocations from several national operators in parallel, which is why you see WAVECREST NETWORKS LIMITED’s blocks alongside other range holders on the same 01245 code. Local switching capacity, historic Openreach exchange footprints, and WAVECREST NETWORKS LIMITED’s wholesale routing arrangements all influence which blocks land in Chelmsford 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 01245 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.
