British Prisons

Finding out which prison someone is in

If someone you know is in prison, but you don’t know which one, the Prisoner Location Service can help you find them.

The easiest way is by going to the web address ( and completing the enquiry form.

You must complete certain fields (for example, your name, date of birth and address) so that the Prisoner Location Service can check your details.

The prisoner is asked if they want to make contact with you. 

Remember though your enquiry may take up to 40 days to complete.
