A genuine National AT phone number

In Austria, the 720 prefix is a non-geographic number, typically used by businesses for nationwide services without tying them to a specific location.

When dialing a 720 prefix, the format is straightforward: +43 (Austria's country code) followed by 720, and then the remaining subscriber number, making it efficient for both domestic and international calls.
