Dark Group Limited in Haslemere

About Dark Group Limited’s Haslemere allocation

When Dark Group Limited is the range holder for +44 1428 it means Ofcom recorded Dark Group Limited as the provider entitled to issue numbers from these blocks when they were first allocated under the UK National Telephone Numbering Plan. 4 Haslemere-facing blocks sit against Dark Group Limited in the current Ofcom snapshot, each of which can carry up to ten thousand individual digits available for assignment to end customers.

Haslemere’s Surrey telecoms estate is shaped by Haslemere's residential and business catchment: a dense urban exchange typically hosts allocations from several national operators in parallel, which is why you see Dark Group Limited’s blocks alongside other range holders on the same 01428 code. Local switching capacity, historic Openreach exchange footprints, and Dark Group Limited’s wholesale routing arrangements all influence which blocks land in Haslemere 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 01428 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.
