Overlay groups in Arizona
Codes in an overlay group can serve the same broad numbering area. A person may keep a number after moving, and the displayed number may be spoofed.

A code cannot verify the owner of a number. If an unexpected caller asks for money or sensitive information, verify the claim independently.
