About KDDI Europe Ltd’s Brentwood allocation

When KDDI Europe Ltd is the range holder for +44 1277 it means Ofcom recorded KDDI Europe Ltd as the provider entitled to issue numbers from these blocks when they were first allocated under the UK National Telephone Numbering Plan. 1 Brentwood-facing block sits against KDDI Europe Ltd in the current Ofcom snapshot, each of which can carry up to ten thousand individual digits available for assignment to end customers.

Brentwood’s Essex telecoms estate is shaped by Brentwood's residential and business catchment: a dense urban exchange typically hosts allocations from several national operators in parallel, which is why you see KDDI Europe Ltd’s blocks alongside other range holders on the same 01277 code. Local switching capacity, historic Openreach exchange footprints, and KDDI Europe Ltd’s wholesale routing arrangements all influence which blocks land in Brentwood 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 01277 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 KDDI Europe Ltd on 01277

Why does KDDI Europe Ltd appear on Brentwood (01277) numbers?

KDDI Europe Ltd is listed in Ofcom's UK Numbering Data feed as the originally-allocated range holder for 1 number block on the 01277 dialling code, which covers Brentwood. That allocation pre-dates any individual customer — it simply means Ofcom recognised KDDI Europe Ltd as the wholesale operator entitled to issue those digits when the block was first allocated.

Are calls from a Brentwood KDDI Europe 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 01277 number into the lookup above to combine the KDDI Europe Ltd range data with a live AI internet check for forum reports, scam databases, and business listings.

Has KDDI Europe Ltd's 01277 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 Any block that has been re-assigned, withdrawn or marked free will appear with its new status on the next refresh.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.
