About Node4 Ltd’s Derby allocation

When Node4 Ltd is the range holder for +44 1332 it means Ofcom recorded Node4 Ltd as the provider entitled to issue numbers from these blocks when they were first allocated under the UK National Telephone Numbering Plan. 6 Derby-facing blocks sit against Node4 Ltd in the current Ofcom snapshot, each of which can carry up to ten thousand individual digits available for assignment to end customers.

Derby’s Derbyshire telecoms estate is shaped by Derby's catchment of roughly 257,000 residents: a dense urban exchange typically hosts allocations from several national operators in parallel, which is why you see Node4 Ltd’s blocks alongside other range holders on the same 01332 code. Local switching capacity, historic Openreach exchange footprints, and Node4 Ltd’s wholesale routing arrangements all influence which blocks land in Derby 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 01332 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 Node4 Ltd on 01332

Why does Node4 Ltd appear on Derby (01332) numbers?

Node4 Ltd is listed in Ofcom's UK Numbering Data feed as the originally-allocated range holder for 6 number blocks on the 01332 dialling code, which covers Derby. That allocation pre-dates any individual customer — it simply means Ofcom recognised Node4 Ltd as the wholesale operator entitled to issue those digits when the block was first allocated.

Are calls from a Derby Node4 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 01332 number into the lookup above to combine the Node4 Ltd range data with a live AI internet check for forum reports, scam databases, and business listings.

Has Node4 Ltd's 01332 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 Any block that has been re-assigned, withdrawn or marked free will appear with its new status on the next refresh.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.
