Red Matter Limited in Ipswich

About Red Matter Limited’s Ipswich allocation

When Red Matter Limited is the range holder for +44 1473 it means Ofcom recorded Red Matter Limited as the provider entitled to issue numbers from these blocks when they were first allocated under the UK National Telephone Numbering Plan. 2 Ipswich-facing blocks sit against Red Matter Limited in the current Ofcom snapshot, each of which can carry up to ten thousand individual digits available for assignment to end customers.

Ipswich’s Suffolk telecoms estate is shaped by Ipswich's residential and business catchment: a dense urban exchange typically hosts allocations from several national operators in parallel, which is why you see Red Matter Limited’s blocks alongside other range holders on the same 01473 code. Local switching capacity, historic Openreach exchange footprints, and Red Matter Limited’s wholesale routing arrangements all influence which blocks land in Ipswich 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 01473 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.
