About Syntec Limited’s Alton allocation
When Syntec Limited is the range holder for +44 1420 it means Ofcom recorded Syntec Limited as the provider entitled to issue numbers from these blocks when they were first allocated under the UK National Telephone Numbering Plan. 2 Alton-facing blocks sit against Syntec Limited in the current Ofcom snapshot, each of which can carry up to ten thousand individual digits available for assignment to end customers.
Alton’s Hampshire telecoms estate is shaped by Alton's residential and business catchment: a dense urban exchange typically hosts allocations from several national operators in parallel, which is why you see Syntec Limited’s blocks alongside other range holders on the same 01420 code. Local switching capacity, historic Openreach exchange footprints, and Syntec Limited’s wholesale routing arrangements all influence which blocks land in Alton 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 01420 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 Syntec Limited on 01420
Why does Syntec Limited appear on Alton (01420) numbers?
Syntec Limited is listed in Ofcom's UK Numbering Data feed as the originally-allocated range holder for 2 number blocks on the 01420 dialling code, which covers Alton. That allocation pre-dates any individual customer — it simply means Ofcom recognised Syntec Limited as the wholesale operator entitled to issue those digits when the block was first allocated.
Are calls from a Alton Syntec 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 01420 number into the lookup above to combine the Syntec Limited range data with a live AI internet check for forum reports, scam databases, and business listings.
Has Syntec Limited's 01420 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 Any block that has been re-assigned, withdrawn or marked free will appear with its new status on the next refresh.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.
