The telephony industry has been an unfortunate target of spam culprits. This can result in numbers being listed by mobile carriers as “Spam likely,” or something similar - Each carrier labels this as they see fit. The good news is, that if you have happened to acquire a number through us or another carrier that is showing this based on past actions with that phone number, you can rectify it with the mobile carrier(s) involved.
It is recommended to register legitimate outbound calling use cases using the Free Caller Registry portal. Mobile carriers like T-Mobile, AT&T, and Verizon use this portal, along with their respective Analytics Engines, to submit their data with all of their systems simultaneously.
Alternatively, this issue is with only one of those carriers you can register with their specific analytics engine separately.
