About NFON UK Ltd’s York allocation

When NFON UK Ltd is the range holder for +44 1904 it means Ofcom recorded NFON UK Ltd as the provider entitled to issue numbers from these blocks when they were first allocated under the UK National Telephone Numbering Plan. 4 York-facing blocks sit against NFON UK Ltd in the current Ofcom snapshot, each of which can carry up to ten thousand individual digits available for assignment to end customers.

York’s North Yorkshire telecoms estate is shaped by York's catchment of roughly 211,000 residents: a dense urban exchange typically hosts allocations from several national operators in parallel, which is why you see NFON UK Ltd’s blocks alongside other range holders on the same 01904 code. Local switching capacity, historic Openreach exchange footprints, and NFON UK Ltd’s wholesale routing arrangements all influence which blocks land in York 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 01904 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 NFON UK Ltd on 01904

Why does NFON UK Ltd appear on York (01904) numbers?

NFON UK Ltd is listed in Ofcom's UK Numbering Data feed as the originally-allocated range holder for 4 number blocks on the 01904 dialling code, which covers York. That allocation pre-dates any individual customer — it simply means Ofcom recognised NFON UK Ltd as the wholesale operator entitled to issue those digits when the block was first allocated.

Are calls from a York NFON UK Ltd-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 01904 number into the lookup above to combine the NFON UK Ltd range data with a live AI internet check for forum reports, scam databases, and business listings.

Has NFON UK Ltd's 01904 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 Any block that has been re-assigned, withdrawn or marked free will appear with its new status on the next refresh.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.
