How to Check Which Phone Number Receives Your Facebook Two-Factor Authentication Code

Two-factor authentication (2FA) is an important security feature on Facebook that helps protect your account from unauthorized access.

When 2FA is enabled, Meta sends a verification code whenever:

• You log in from a new device or browser

• You attempt sensitive security changes

• Meta detects unusual login activity

Many users are unsure which phone number is currently linked to their 2FA setup, especially because Facebook displays the number in a masked format.

This guide explains how to verify the phone number connected to your two-factor authentication and how to view the full number in your account settings.
