Onvoy Communications Ltd. in Edinburgh

About Onvoy Communications Ltd.’s Edinburgh allocation

When Onvoy Communications Ltd. is the range holder for +44 131 it means Ofcom recorded Onvoy Communications Ltd. as the provider entitled to issue numbers from these blocks when they were first allocated under the UK National Telephone Numbering Plan. 2 Edinburgh-facing blocks sit against Onvoy Communications Ltd. in the current Ofcom snapshot, each of which can carry up to ten thousand individual digits available for assignment to end customers.

Edinburgh’s Scotland telecoms estate is shaped by Edinburgh's catchment of roughly 530,000 residents: a dense urban exchange typically hosts allocations from several national operators in parallel, which is why you see Onvoy Communications Ltd.’s blocks alongside other range holders on the same 0131 code. Local switching capacity, historic Openreach exchange footprints, and Onvoy Communications Ltd.’s wholesale routing arrangements all influence which blocks land in Edinburgh 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 0131 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.
