AT&T uses standard GSM MMI codes for conditional call forwarding. The same codes work on AT&T Mobility, AT&T Cricket, and FirstNet — all three run on AT&T's GSM network.
The same codes work on Cricket, FirstNet (MVNOs running on AT&T's network).
Working codes for AT&T
- Forward all calls (CFU):
**21*NUMBER# - Forward when no answer (CFNA):
**61*NUMBER# - Forward when busy (CFB):
**67*NUMBER# - Forward when unreachable (CFNR):
**62*NUMBER# - Cancel all forwarding:
##21#
Replace NUMBER with the destination phone number (e.g. your VettedCalls extension). Dial the code from your regular phone keypad and press send. Listen for a confirmation tone.
Troubleshooting AT&T forwarding
- No confirmation tone after dialing? Some AT&T plans require enabling Voice Mail before forwarding works. Dial *#62# to check current settings.
- Forwarding "stuck" — calls won't come back? Dial
##002#to cancel ALL forwarding (CFU, CFNA, CFB, CFNR at once). - Codes work on Wi-Fi calling? Yes, AT&T forwarding is set at the carrier level and applies whether the call hits cell or Wi-Fi.
