0845 Service rate numbers UK

About 0845 numbers in the UK

The 0845 prefix is part of the UK National Telephone Numbering Plan administered by Ofcom and falls into the Service number family. 0845 was a widely-used 'lo-call' business number. Since 2015 the caller pays an access charge plus a service charge of up to 7p/min, so many organisations have moved to 03 numbers. Calls are no longer charged at local rate.

Ofcom allocates 0845 number ranges to UK communications providers (Range Holders) in 1,000- or 10,000-number blocks. The table below lists every currently-allocated block we have ingested from Ofcom’s weekly Numbering Data feed. Click any Range Holder to see their full UK portfolio, or paste a specific number into the lookup form above to see the originating provider, the allocation status, and a live AI internet check for any public reports about that exact number.

Spotting a fake 0845 call

• Check the Range Holder column below: a 0845 number that doesn’t map cleanly to one of the UK-licensed providers listed is the first amber flag. Genuine UK callers on this prefix come through one of the carriers Ofcom has actually allocated the block to.
• Watch the script. Legitimate 0845 callers — whether banks, delivery firms, public-sector services or commercial brands — don’t pressure you into reading codes from a text, keying in passwords, or installing remote-access software while still on the line.
• If you weren’t expecting a 0845 call, hang up and ring back via a number printed on the organisation’s website or a recent letter, not the CLI that just rang you. Most 0845 scams collapse the moment you switch to a verified channel.
• Paste the exact digits into the lookup form above for a live AI internet check. If the number has been mass-reported on consumer forums, that surfaces in the per-number result alongside the structured Ofcom Range Holder data.
