Buzz Networks Limited in Alton

About Buzz Networks Limited’s Alton allocation

When Buzz Networks Limited is the range holder for +44 1420 it means Ofcom recorded Buzz Networks Limited as the provider entitled to issue numbers from these blocks when they were first allocated under the UK National Telephone Numbering Plan. 2 Alton-facing blocks sit against Buzz Networks Limited in the current Ofcom snapshot, each of which can carry up to ten thousand individual digits available for assignment to end customers.

Alton’s Hampshire telecoms estate is shaped by Alton's residential and business catchment: a dense urban exchange typically hosts allocations from several national operators in parallel, which is why you see Buzz Networks Limited’s blocks alongside other range holders on the same 01420 code. Local switching capacity, historic Openreach exchange footprints, and Buzz Networks Limited’s wholesale routing arrangements all influence which blocks land in Alton 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 01420 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.
