How to use this list
This page groups active phone prefixes by country and line type. It helps users understand the expected number format before opening a specific prefix or checking a complete number.

A prefix alone is not proof that a call is safe or unsafe. If a caller asks for money, passwords, card details or urgent verification, check the complete number before taking action.
