About Mission Labs Limited’s Blackburn allocation
When Mission Labs Limited is the range holder for +44 1254 it means Ofcom recorded Mission Labs 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 Mission Labs 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 Mission Labs Limited’s blocks alongside other range holders on the same 01254 code. Local switching capacity, historic Openreach exchange footprints, and Mission Labs 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.

FAQs about Mission Labs Limited on 01254
Why does Mission Labs Limited appear on Blackburn (01254) numbers?
Mission Labs Limited is listed in Ofcom's UK Numbering Data feed as the originally-allocated range holder for 2 number blocks on the 01254 dialling code, which covers Blackburn. That allocation pre-dates any individual customer — it simply means Ofcom recognised Mission Labs Limited as the wholesale operator entitled to issue those digits when the block was first allocated.
Are calls from a Blackburn Mission Labs Limited-allocated number safe?
An Ofcom allocation only tells you which provider the block was issued to; it is not a safety verdict. UK numbers can be ported between networks, and any UK area code can be spoofed by an overseas caller. Paste the specific 01254 number into the lookup above to combine the Mission Labs Limited range data with a live AI internet check for forum reports, scam databases, and business listings.
Has Mission Labs Limited's 01254 block been updated recently?
Yes — the table above is sourced from Ofcom's public UK Numbering Data feed, which we re-ingest every week (typically Wednesday). Any block that has been re-assigned, withdrawn or marked free will appear with its new status on the next refresh. Numbers within an allocated block can still be ported to another carrier in between Ofcom updates; see our range-holder-vs-current-provider guide for the distinction.
