GCI Network Solutions Limited in Northampton

About GCI Network Solutions Limited’s Northampton allocation

When GCI Network Solutions Limited is the range holder for +44 1604 it means Ofcom recorded GCI Network Solutions Limited as the provider entitled to issue numbers from these blocks when they were first allocated under the UK National Telephone Numbering Plan. 48 Northampton-facing blocks sit against GCI Network Solutions Limited in the current Ofcom snapshot, each of which can carry up to ten thousand individual digits available for assignment to end customers.

Northampton’s Northamptonshire telecoms estate is shaped by Northampton's catchment of roughly 224,000 residents: a dense urban exchange typically hosts allocations from several national operators in parallel, which is why you see GCI Network Solutions Limited’s blocks alongside other range holders on the same 01604 code. Local switching capacity, historic Openreach exchange footprints, and GCI Network Solutions Limited’s wholesale routing arrangements all influence which blocks land in Northampton 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 01604 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.
