Colt Technology Services in Aberdeen

About Colt Technology Services’s Aberdeen allocation

When Colt Technology Services is the range holder for +44 1224 it means Ofcom recorded Colt Technology Services as the provider entitled to issue numbers from these blocks when they were first allocated under the UK National Telephone Numbering Plan. 30 Aberdeen-facing blocks sit against Colt Technology Services in the current Ofcom snapshot, each of which can carry up to ten thousand individual digits available for assignment to end customers.

Aberdeen’s Scotland telecoms estate is shaped by Aberdeen's catchment of roughly 200,000 residents: a dense urban exchange typically hosts allocations from several national operators in parallel, which is why you see Colt Technology Services’s blocks alongside other range holders on the same 01224 code. Local switching capacity, historic Openreach exchange footprints, and Colt Technology Services’s wholesale routing arrangements all influence which blocks land in Aberdeen 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 01224 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.
