Sark Telecom B.V. in Leeds

About Sark Telecom B.V.’s Leeds allocation

When Sark Telecom B.V. is the range holder for +44 113 it means Ofcom recorded Sark Telecom B.V. as the provider entitled to issue numbers from these blocks when they were first allocated under the UK National Telephone Numbering Plan. 2 Leeds-facing blocks sit against Sark Telecom B.V. in the current Ofcom snapshot, each of which can carry up to ten thousand individual digits available for assignment to end customers.

Leeds’s Yorkshire telecoms estate is shaped by Leeds's catchment of roughly 793,000 residents: a dense urban exchange typically hosts allocations from several national operators in parallel, which is why you see Sark Telecom B.V.’s blocks alongside other range holders on the same 0113 code. Local switching capacity, historic Openreach exchange footprints, and Sark Telecom B.V.’s wholesale routing arrangements all influence which blocks land in Leeds 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 0113 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.
