Nationwide Telephone Assistance Ltd in Abingdon

About Nationwide Telephone Assistance Ltd’s Abingdon allocation

When Nationwide Telephone Assistance Ltd is the range holder for +44 1235 it means Ofcom recorded Nationwide Telephone Assistance Ltd as the provider entitled to issue numbers from these blocks when they were first allocated under the UK National Telephone Numbering Plan. 2 Abingdon-facing blocks sit against Nationwide Telephone Assistance Ltd in the current Ofcom snapshot, each of which can carry up to ten thousand individual digits available for assignment to end customers.

Abingdon’s Oxfordshire telecoms estate is shaped by Abingdon's residential and business catchment: a dense urban exchange typically hosts allocations from several national operators in parallel, which is why you see Nationwide Telephone Assistance Ltd’s blocks alongside other range holders on the same 01235 code. Local switching capacity, historic Openreach exchange footprints, and Nationwide Telephone Assistance Ltd’s wholesale routing arrangements all influence which blocks land in Abingdon 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 01235 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.
