Questions about checking UK numbers

How do I know if a UK phone number is valid?

Type it into the checker above. A valid UK number has 11 digits starting with 0 (for example 0161 496 0000) or 10 digits after +44. The checker also confirms the number belongs to a range that is in use in the UK numbering plan.

How can I tell if a number is a landline or a mobile?

UK mobile numbers start with 07 (except 070 personal and 076 pager numbers). Landlines start with 01 or 02 and include an area code. Numbers starting with 03, 080, 084, 087 or 09 are non-geographic. The checker shows the exact type for you.

What is the international format of a UK number?

Drop the first 0 and add +44 in front: 01536 857648 becomes +44 1536 857648. In systems and spreadsheets the E.164 format without spaces is used: +441536857648.

How do I call a UK number from abroad?

Dial your country's exit code, then 44, then the number without the first 0. From the USA or Canada that is 011 44, from most of Europe 00 44. On a mobile you can simply dial +44.

Can the checker tell me who owns a number?

No. It shows the number type, the area for landlines and the company that holds the number range, plus any reports from people who received calls from it. Private subscriber details are never shown.
