What's a legitimate reverse-lookup site for the UK?

Where you enter a person's phone number and it tells you their name and/or address.



Thanks in advance. :)What's a legitimate reverse-lookup site for the UK?
Register and log on to royalmail.com and input what address you have and it will verify the details for you. You can't access a name though.

You do get up to 12 searches a day .

There is no service that can verify a person's name
