IDT Global Limited in Blackburn

About IDT Global Limited’s Blackburn allocation

When IDT Global Limited is the range holder for +44 1254 it means Ofcom recorded IDT Global Limited as the provider entitled to issue numbers from these blocks when they were first allocated under the UK National Telephone Numbering Plan. 2 Blackburn-facing blocks sit against IDT Global Limited in the current Ofcom snapshot, each of which can carry up to ten thousand individual digits available for assignment to end customers.

Blackburn’s Lancashire telecoms estate is shaped by Blackburn's residential and business catchment: a dense urban exchange typically hosts allocations from several national operators in parallel, which is why you see IDT Global Limited’s blocks alongside other range holders on the same 01254 code. Local switching capacity, historic Openreach exchange footprints, and IDT Global Limited’s wholesale routing arrangements all influence which blocks land in Blackburn 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 01254 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.
