Mars Communications Limited in Abergavenny

About Mars Communications Limited’s Abergavenny allocation

When Mars Communications Limited is the range holder for +44 1873 it means Ofcom recorded Mars Communications Limited as the provider entitled to issue numbers from these blocks when they were first allocated under the UK National Telephone Numbering Plan. 2 Abergavenny-facing blocks sit against Mars Communications Limited in the current Ofcom snapshot, each of which can carry up to ten thousand individual digits available for assignment to end customers.

Abergavenny’s Wales telecoms estate is shaped by Abergavenny's residential and business catchment: a dense urban exchange typically hosts allocations from several national operators in parallel, which is why you see Mars Communications Limited’s blocks alongside other range holders on the same 01873 code. Local switching capacity, historic Openreach exchange footprints, and Mars Communications Limited’s wholesale routing arrangements all influence which blocks land in Abergavenny rather than elsewhere on the national plan.

Treat this allocation as a starting point, not a verdict on any specific caller.
