If your phone number is being flagged as spam or scam when calling others, it may be due to carrier spam detection algorithms designed to reduce robocalls. This can happen even to legitimate callers, particularly businesses that make frequent outbound calls.
To dispute a spam label, you can submit a request to the recipient's phone carrier. Most major carriers provide an online form or email contact for reviewing and removing incorrect spam flags.
The fastest way to request removal from multiple carriers is through the Free Caller Registry.
If the issue persists, you may need to contact the carrier of the person you are trying to reach to request a review of your number.
If you are a business and make frequent calls, you may want to register your number with major carriers to reduce the chances of being flagged in the future.
