Entanet International Ltd in Southampton & Portsmouth

About Entanet International Ltd’s Southampton & Portsmouth allocation

When Entanet International Ltd is the range holder for +44 23 it means Ofcom recorded Entanet International 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 Entanet International 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 Entanet International Ltd’s blocks alongside other range holders on the same 023 code. Local switching capacity, historic Openreach exchange footprints, and Entanet International 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.
