Frome — 01373 dialling code

About the 01373 dialling code in Frome

01373 is the geographic UK area code anchored on Frome, Somerset, listed in Ofcom’s National Telephone Numbering Plan. The code reaches across the wider charging area surrounding Frome rather than the town centre alone. When an inbound UK landline shows +44 1373 on Caller-ID, the originating exchange is most likely physically located in or near Frome, with neighbouring exchanges on 01300, 01302, 01303.

Numbers in Frome’s 01373 block were originally allocated to UK communications providers in 1,000-number sub-ranges (the legacy Ofcom block size for geographic codes), with newer allocations issued in 10,000-number blocks once the smaller blocks ran out. Each block is delegated to a Range Holder — typically Openreach (BT), Virgin Media O2, Sky, Gamma Telecom or one of a long tail of regional carriers — who is then responsible for assigning individual numbers to end-customers in the Frome charging area. The full table further down this page shows every currently-allocated range on 01373 and the holder it was delegated to.

This is the same data Ofcom publishes every Wednesday in the public UK Numbering Data feed; we re-ingest the snapshot weekly, so the Frome allocations you see here are at most seven days old. Because UK numbers are portable, the current carrier of any specific 01373 number in Frome can differ from the Range Holder shown — see Range Holder vs current provider for the explanation. To identify a specific caller, paste the full number into the lookup above: you’ll get the Range Holder, the allocation status, the Frome area-code metadata, and any verdicts other callers have left on that exact number (see AI chatbot vs database lookup for how that compares with asking a chatbot).

From abroad, a Frome 01373 number is reached by dialling the international access prefix (00 from most of Europe, 011 from North America), then 44, then the local digits with the leading zero dropped. So a number written locally as 01373 123 4567 becomes +44 1373 123 4567 when dialled from outside the UK. Inbound calls to a Frome landline are charged at the recipient’s standard call-receive rate (free in most consumer tariffs), and outbound calls from a UK mobile or landline to a 01373 number are billed at the caller’s own UK landline rate. Somerset consumers and businesses with a 01373 CLI typically use Openreach copper or fibre, Virgin Media O2 cable, a Sky or TalkTalk retail bundle, or one of a long tail of regional or VoIP-based providers — the table further down this page shows the wholesale allocation that anchors each block, but the live retail carrier on a specific number can be different after porting.

If you have just received a missed call from a 01373 number and you don’t recognise it, the most reliable next step is to paste the full number into the lookup above before calling back. The Ofcom Range Holder data tells you which wholesale carrier the block was issued to, which often gives away whether the call is a local resident, a national business renting a Frome-presenting CLI, or a VoIP service that could be operating from anywhere in the UK. The caller verdicts and community reports then show what other people who received a call from the specific digits said about it — scam, nuisance or safe, often with a short comment — so you have context before you decide whether to ring back.

01373 by the numbers

Frome is one of 15 geographic dialling codes in Somerset. The 01373 dialling code serving Frome has 361 number ranges on file across 92 distinct Ofcom Range Holders, of which 34% are in active Allocated status. The allocated prefixes run from +44 137300 through +44 137399.

The visible blocks on 01373 are predominantly geographic (01 / 02) (100%). A number sitting inside an Allocated 01373 block is in active service with a UK customer in or near the Frome charging area, whereas one claimed to come from a Reserved, Designated or Free block almost certainly isn’t the genuine origin and points instead at a spoofed Caller-ID worth treating with caution. The full table below lists every visible block and the Range Holder it was delegated to.
