## FAQ
- **How does Traceback reveal a No Caller ID number?** Traceback reveals the real number behind every No Caller ID call using conditional call forwarding, a standard carrier feature. Setup takes about 47 seconds. Unanswered or declined calls then route through our reveal server, which returns the caller's real number and the name when available within seconds. Works on every iPhone and Android, with the app closed, on Verizon, AT&T, T-Mobile, and other major US carriers.
- **What does No Caller ID mean on iPhone?** No Caller ID is the label iPhone shows when an incoming call hides its number from your phone's caller-ID system. The caller still has a real number, the carrier just refuses to display it. Traceback identifies the underlying number by routing the call through our reveal server before it reaches your screen, so an unknown caller becomes a name you recognize within seconds.
- **How do I find out who called from a No Caller ID number?** Set up Traceback once, in about 47 seconds, and every future No Caller ID call gets revealed automatically. When the unknown number rings, decline the call or let it ring out. Within seconds, you see the real number, the caller's name when available, and any prior history. No live tracing, no tapping, no app to keep open.
- **Which US carriers does Traceback work with?** Traceback works on Verizon, AT&T, T-Mobile, Cricket Wireless, Metro by T-Mobile, Mint Mobile, Spectrum Mobile, Visible, Xfinity Mobile, and US Cellular. Activation is one tap, about 47 seconds, using your carrier's standard call-forwarding code. No SIM swap, no carrier change.
- **Can I trace a No Caller ID call legally?** Yes. Tracing a No Caller ID call with Traceback is legal in all 50 states. Conditional call forwarding is a standard service US carriers sell to their subscribers, so routing an unknown caller through a reveal server is a normal use of your own line. Traceback never records conversations, only identifies the originating number.
- **Can Traceback reveal No Caller ID calls I received before signup?** Unfortunately, no. Traceback identifies calls by routing them through our reveal server. Calls from before activation never passed through, so there's nothing to identify retroactively. Set Traceback up now, and every future No Caller ID call gets revealed. Most repeat callers try again within hours or days, and the next ring will show their real number.
