Android: How to Identify Unknown Calls
Want to know who's behind those "No Caller ID" and "Unknown" calls on your Android? With Traceback set up, you can identify them and see the real caller.
Identify Unknown Calls with Traceback
Make sure call forwarding is set up: the forwarding number (shown in the app for your carrier) entered under "Forward when busy."
When a No Caller ID or Unknown call comes in, Decline it.
The call forwards to Traceback and our system reveals the number.
You'll see the revealed number, plus a name if it's in our database or your synced contacts.
Get the Caller's Name Too
Privacy Note
Traceback identifies a hidden caller from the forwarded call only. A name appears when the number is in our database or your synced contacts, otherwise you'll see just the revealed number.
Troubleshooting
The call wasn't identified. Confirm forwarding is set under "Forward when busy," that you declined the call, and that voicemail didn't answer first.
I only see a number, no name. Normal when the number isn't in our database or contacts. Sync your contacts to catch known callers.
Spoofed-looking numbers aren't revealed. Traceback identifies No Caller ID and Unknown calls, not spoofed (faked) numbers.
Frequently Asked Questions
How do I identify an unknown call on Android?
With Traceback set up, decline the No Caller ID or Unknown call. It forwards to us and the number is revealed.
Can I see the name, not just the number?
Yes, when the number is in our database or your synced contacts. Sync contacts in Settings to match known callers.
Does identifying a blocked number work on any Android phone?
It works on supported Israeli carrier lines (not prepaid or Wecom) with call forwarding set under "Forward when busy."
Why is a call still showing as Unknown?
Make sure you declined it and the call forwarded to us before voicemail picked it up.
