About Eircom (UK) Limited’s Dover allocation

When Eircom (UK) Limited is the range holder for +44 1304 it means Ofcom recorded Eircom (UK) Limited as the provider entitled to issue numbers from these blocks when they were first allocated under the UK National Telephone Numbering Plan. 1 Dover-facing block sits against Eircom (UK) Limited in the current Ofcom snapshot, each of which can carry up to ten thousand individual digits available for assignment to end customers.

Dover’s Kent telecoms estate is shaped by Dover's residential and business catchment: a dense urban exchange typically hosts allocations from several national operators in parallel, which is why you see Eircom (UK) Limited’s blocks alongside other range holders on the same 01304 code. Local switching capacity, historic Openreach exchange footprints, and Eircom (UK) Limited’s wholesale routing arrangements all influence which blocks land in Dover 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 01304 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 Eircom (UK) Limited on 01304

Why does Eircom (UK) Limited appear on Dover (01304) numbers?

Eircom (UK) Limited is listed in Ofcom's UK Numbering Data feed as the originally-allocated range holder for 1 number block on the 01304 dialling code, which covers Dover. That allocation pre-dates any individual customer — it simply means Ofcom recognised Eircom (UK) Limited as the wholesale operator entitled to issue those digits when the block was first allocated.

Are calls from a Dover Eircom (UK) Limited-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 01304 number into the lookup above to combine the Eircom (UK) Limited range data with a live AI internet check for forum reports, scam databases, and business listings.

Has Eircom (UK) Limited's 01304 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 Any block that has been re-assigned, withdrawn or marked free will appear with its new status on the next refresh.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.
