If you're setting up a call-screening service - VettedCalls or otherwise - you need the right conditional forwarding codes for your carrier. Here are the working codes for every major US mobile carrier, tested in 2026.
AT&T, Cricket, FirstNet
Standard GSM MMI codes. Dial each and listen for a confirmation tone:
- **61*NUMBER# - Forward on no-answer (rings N times, then forwards)
- **62*NUMBER# - Forward when unreachable (phone off / no signal)
- **67*NUMBER# - Forward on busy (rings back or declined)
- ##002# - Cancel all conditional forwarding
T-Mobile, Metro by T-Mobile, Boost Mobile, Google Fi
Same standard GSM codes as AT&T. T-Mobile's network is GSM-native so these all work:
- **61*NUMBER# - no-answer
- **62*NUMBER# - unreachable
- **67*NUMBER# - busy
Verizon
Verizon uses CDMA-era codes. Different dial strings, different confirmation behaviour:
- *71NUMBER - Conditional forwarding on no-answer (no # at the end). Hit Send, wait for confirmation tone.
- *90NUMBER - Forward on busy. Same process.
- *73 - Cancel forwarding.
Note: Some Verizon plans require toggling call-forwarding in the MyVerizon app instead. If the dial codes produce no confirmation, check there.
US Cellular
Standard GSM MMI codes (same as AT&T).
Consumer Cellular, Straight Talk, MVNOs
These are resellers - the codes depend on which underlying network the plan uses. Consumer Cellular on AT&T network uses AT&T codes; on T-Mobile network uses T-Mobile codes. Straight Talk varies by SIM. Usually **61*/**62*/**67* works, but if nothing confirms, the carrier may require a customer-service call to enable CFNA/CFB at the account level.
Testing your forwarding
After dialing the codes, verify them with *#61#, *#62#, and *#67# - your phone will show the current forwarding target. Then ask a friend (whose number you don't have saved) to call you. If you don't pick up, the call should route to your VettedCalls number within ~20 seconds on iPhone (or instantly on Android with the VettedCalls app installed).
