Net-Work Internet Ltd in Southampton & Portsmouth

About Net-Work Internet Ltd’s Southampton & Portsmouth allocation

When Net-Work Internet Ltd is the range holder for +44 23 it means Ofcom recorded Net-Work Internet Ltd as the provider entitled to issue numbers from these blocks when they were first allocated under the UK National Telephone Numbering Plan. 4 Southampton & Portsmouth-facing blocks sit against Net-Work Internet Ltd in the current Ofcom snapshot, each of which can carry up to ten thousand individual digits available for assignment to end customers.

Southampton & Portsmouth’s South Coast telecoms estate is shaped by Southampton & Portsmouth's catchment of roughly 540,000 residents: a dense urban exchange typically hosts allocations from several national operators in parallel, which is why you see Net-Work Internet Ltd’s blocks alongside other range holders on the same 023 code. Local switching capacity, historic Openreach exchange footprints, and Net-Work Internet Ltd’s wholesale routing arrangements all influence which blocks land in Southampton & Portsmouth 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 023 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.
