Traceback is an iPhone app designed to reveal the real phone number behind No Caller ID, blocked, and hidden calls. It can also show the caller’s name when that information is available, helping you understand who is actually trying to contact you instead of leaving you guessing.
Most people discover Traceback after dealing with the same frustrating situation. Maybe an ex keeps calling from hidden numbers. Perhaps your phone number was posted somewhere publicly and you started receiving anonymous calls. It could be a debt collector, spammer, prank caller, or someone making unwanted or threatening calls while hiding their identity behind “No Caller ID.” In these situations, simply blocking a number is not enough—because there is no visible number to block in the first place.
Changing your phone number can feel like an extreme solution. It means updating friends, family, work contacts, services, accounts, and countless other places where your number is connected. And even after all that effort, there is always the possibility that the new number could eventually become exposed again.
Traceback offers a simpler alternative: find out who is behind the hidden call.
Getting started takes less than a minute. You set up call forwarding once, and from that point, Traceback works automatically in the background to reveal hidden and No Caller ID calls. When a hidden caller contacts you, you receive a real-time notification with the revealed phone number, so you can immediately see who is trying to reach you.
Depending on the available information, Traceback can also identify the caller by name. Every revealed call is saved in your call history, giving you a clear record of anonymous calls you have received. This can be particularly useful if unwanted calls continue over time and you need to keep track of when and how often someone contacted you.
With Traceback, you get:
The real number behind blocked, hidden, and No Caller ID calls
The caller’s name when available
Instant notifications when a hidden call is revealed
A complete history of revealed calls for your records
A simple setup process that takes less than a minute
Privacy is also a core part of the service. Your calls are never shared with third parties.
Traceback has already revealed more than 380,000 calls and has earned a 4.7-star rating on the App Store. Whether you are dealing with persistent unwanted calls, anonymous harassment, suspicious callers, or simply want to know who is behind a hidden number, Traceback gives you more visibility and control over who is calling your phone.
