Why do some phone numbers have an address requirement, and what is a valid proof of address?

Local regulations in some countries often require providing adequate identity documentation to carriers or a local enforcement agency.

Local regulations differ per country and some phone numbers require the end-user to be located within or outside of a geographic boundary. To purchase these numbers, you will need to provide, and keep updated, a valid business or personal address that satisfies the requirement. The address must be the residence or place of business of the individual or entity using the phone number.

Some examples of documents that can be used as your proof of address are:

• Monthly bank statements
• Public utility bill
• Government documents
