What is a spam call?
A spam call is a call made from a number that has been flagged as suspicious by any of the carriers involved, or a call originating from a phone number that the carrier cannot identify. Customers may see their outbound calls display as "Spam," "Spam Likely," "Scam Likely," etc., to recipients in their caller ID. Calls may even be blocked altogether.
Why does spam flagging or call blocking exist:
Spam flagging aims to protect consumers against:
- Unidentified calls
- Robocalling: high-volume, short-duration calls originating from a single number
- Illegal Calls
- Unwanted Calls
As such, regulators and major phone carriers have implemented protective actions to help reduce the occurrence of robocalling, illegal calls, unwanted calls, and calls made from unidentified phone numbers.
Some reasons your number could be blocked or flagged as spam are:
- If your calls are being blocked to T-Mobile devices, you need to register your phone number with FirstOrion, a free service that T-Mobile uses to identify calls from verified phone numbers. If you are not registered with FirstOrion, this is the most important thing you can do to fix this issue and only takes a few minutes.
- Your phone number is not registered with Hiya, a free service just like FirstOrion, used by AT&T to identify calls from verified phone numbers.
- Consumers may have reported your phone number to their telecom carriers, resulting in your phone number being flagged as spam. This is unlikely, but you can fill out a form to have your phone number removed from this list here: https://reportarobocall.com/trf/
Just like Hiya and FirstOrion, here is the Verizon registration option, which is free and easy to register with: https://www.voicespamfeedback.com/vsf/
- High volume short calls: Typically under 50 seconds
- High volume of unanswered calls
