Review suspicious traffic
Check a calling number seen in traffic before your fraud team decides what to do.

A useful signal when a call looks wrong
Voice providers screen calling numbers against DNO lists. When your team reviews suspect traffic or a disputed block, a dated source result gives them another fact to consider alongside the rest of the call.
- Listed
- This source says the number should not originate calls.
- Not listed
- No listing in this source at the time checked.
- Unavailable
- The source did not return an answer. Use your defined fallback or try again later.
