CodeLook has two main functions, looking up partial UK telephone numbers to find the locality and call costs, and looking up locality names and post codes to find the code.  For localities and post code, broadband ADSL and fibre availability information is provided. The CodeLook database is updated every one or two weeks.

The partial telephone number can be UK national, international. UK mobile, UK premium, a UK service or UK indirect code. It may be a combined indirect code and partial number. Numbers are entered as dialled from UK landline and mobile telephones.  

New Allocated in the Number Status column shows active numbers, Protected, Quarantined, Reseved and Free are numbers not currently in-use or never used, Ofcom use of status has varied over the years.  Note Ofcom data does not include all non-allocated numbers.  

Please note this site is intended to look up UK telephone numbers, it lists some international numbers but only with country names and those numbers necessary to identify more expensive international calls. No personal information is returned by CodeLook, it is not possible to find the user of a landline or mobile number without a legal court order.

When searching localities and area codes, postal county and island names may be entered.  Historic information is available for some numbers, also the Ofcom CUPID and other codes used by licensed operators.
