About the 01507 dialling code in Louth
01507 is the geographic UK area code anchored on Louth, Lincolnshire, listed in Ofcom’s National Telephone Numbering Plan. The code reaches across the wider charging area surrounding Louth rather than the town centre alone. When an inbound UK landline shows +44 1507 on Caller-ID, the originating exchange is most likely physically located in or near Louth, with neighbouring exchanges on 01501, 01502, 01503.
Numbers in Louth’s 01507 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 Louth charging area. The full table further down this page shows every currently-allocated range on 01507 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 Louth allocations you see here are at most seven days old. Because UK numbers are portable, the current carrier of any specific 01507 number in Louth 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 Louth area-code metadata, and a live AI internet check summarising any public web reports about that exact number.
From abroad, a Louth 01507 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 01507 123 4567 becomes +44 1507 123 4567 when dialled from outside the UK. Inbound calls to a Louth 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 01507 number are billed at the caller’s own UK landline rate. Lincolnshire consumers and businesses with a 01507 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 01507 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 Louth-presenting CLI, or a VoIP service that could be operating from anywhere in the UK. The AI internet check then aggregates any public reports about the specific digits — Reddit threads, MoneySavingExpert forum posts, Trustpilot reviews, scam-reporting databases — so you have context before you decide whether to ring back.

Where is the 01507 dialling code used outside Louth?
01507 is the geographic dialling code anchored on Louth, but the area covered by an Ofcom 01/02 code is broader than the principal town alone — it usually extends across surrounding suburbs and villages within the same charging area, all within Lincolnshire. Number portability also means a 01507 number can be used by a subscriber who has since moved elsewhere in the UK.
How do I dial a Louth 01507 number from outside the UK?
Dial your country's international access prefix (00 from most of Europe, 011 from North America, 0011 from Australia), then 44, then the 01507 number with the leading zero dropped. So a Louth number written locally as 01507 123 4567 becomes +44 1507 123 4567 in international format. The leading zero is a UK-internal national-significant prefix and is always replaced by +44 when calling from abroad.
Why might a 01507 number actually be calling from outside Louth?
Three reasons. First, Ofcom number portability: a customer can keep their 01507 number after moving anywhere in the UK, so the registered subscriber may not be in Louth any more. Second, business CLIs: a national call-centre can present a 01507 number on outbound calls to look local. Third, VoIP services often issue geographic numbers regardless of where the underlying subscriber actually lives. The fastest way to confirm origin is to use the lookup above and read the AI internet check — public reports often surface the actual caller even when the registered 01507 block doesn't match.
