Citrus Telecommunications Ltd in Glasgow

About Citrus Telecommunications Ltd’s Glasgow allocation

When Citrus Telecommunications Ltd is the range holder for +44 141 it means Ofcom recorded Citrus Telecommunications Ltd as the provider entitled to issue numbers from these blocks when they were first allocated under the UK National Telephone Numbering Plan. 6 Glasgow-facing blocks sit against Citrus Telecommunications Ltd in the current Ofcom snapshot, each of which can carry up to ten thousand individual digits available for assignment to end customers.

Glasgow’s Scotland telecoms estate is shaped by Glasgow's catchment of roughly 635,000 residents: a dense urban exchange typically hosts allocations from several national operators in parallel, which is why you see Citrus Telecommunications Ltd’s blocks alongside other range holders on the same 0141 code. Local switching capacity, historic Openreach exchange footprints, and Citrus Telecommunications Ltd’s wholesale routing arrangements all influence which blocks land in Glasgow 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 0141 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.
