About Essensys (UK) Limited’s Northampton allocation

Northampton’s Northamptonshire telecoms estate is shaped by Northampton's catchment of roughly 224,000 residents: a dense urban exchange typically hosts allocations from several national operators in parallel, which is why you see Essensys (UK) Limited’s blocks alongside other range holders on the same 01604 code. Local switching capacity, historic Openreach exchange footprints, and Essensys (UK) Limited’s wholesale routing arrangements all influence which blocks land in Northampton 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 01604 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 Essensys (UK) Limited on 01604
Why does Essensys (UK) Limited appear on Northampton (01604) numbers?
Essensys (UK) Limited is listed in Ofcom's UK Numbering Data feed as the originally-allocated range holder for 2 number blocks on the 01604 dialling code, which covers Northampton. That allocation pre-dates any individual customer — it simply means Ofcom recognised Essensys (UK) Limited as the wholesale operator entitled to issue those digits when the block was first allocated.
Are calls from a Northampton Essensys (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 01604 number into the lookup above to combine the Essensys (UK) Limited range data with a live AI internet check for forum reports, scam databases, and business listings.
Has Essensys (UK) Limited's 01604 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 Any block that has been re-assigned, withdrawn or marked free will appear with its new status on the next refresh.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.
