find the uk addresss from a uk phone number?

If it's a company, then a Google search should find it. If it's an individual then the first part of the number tells the area, or you might be lucky with Google if the person has for example posted on a council web site.

You cannot - you need a human mediator.

You can't.

Not possible - not all phone numbers are listed in a book as some properties do NOT have a landline and it is ILLEGAL for mobile phone companies to give out the addresses of their customers.

To locate the address of a person in the United Kingdom, you can use a telephone number to perform a reverse telephone number search. There are plenty of reverse telephone number search directories on the Internet that specialize in U.K. numbers. Unfortunately, none of them is free. You must pay to get detailed information, including the name and the address of the phone number's owner.

Much cheaper way would be to call the number and ask where they are located.

the first numbers tell you what part of the country the address is and the name is in the Phone book for that area with the address
