How to remove Spam Likely on US Carriers?
The definitive guide for phone professionals.
Quick answer
You cannot easily "remove" the Spam Likely flag. The STIR/SHAKEN system is automatic and carriers do not process individual removal requests.
Success rate: ~10% via Free Caller Registry, 10-15% via Hiya/First Orion, 70-90% via resting. The only reliable solution is extended rest or changing the number.

Why was your number flagged?
Inconsistent Volume
Too many calls per minute from a single mobile or landline.
User Reports
Recipients clicked "Report as spam" via the Phone app.
Short Calls
An abnormally high rate of hang-ups before 5 seconds of conversation.
Low STIR/SHAKEN Attestation
Your carrier assigns B or C attestation instead of full A attestation.
DANGER ZONE: DO NOT DO THIS
Change number immediatelyContinuing with the same script on a new number will burn it within 48h.
Harass carrier supportCarrier support does not have technical access to reputation servers.
Keep calling hoping it will passEach call with a flagged number generates new reports and worsens the situation.
Make "test calls" during restA single call can reactivate the flag and cancel weeks of rest.
Trust "unblocking services"If someone promises to "unblock" your number for a fee, it is a scam. Nobody can do that.
