It is an issue that has increased in frequency recently with iPhone users as well as T-Mobile customers since T-Mobile launched their Scam ID feature that flags potential scam calls on caller ID automatically. AT&T has a similar feature called Call Protect while Verizon also has a Spam Alerts feature. In early 2019, Google (Android) also started rolling out automatic spam and scam protection on their devices.
There is no uniform way to opt-out or be removed from these scam lists as they are maintained and run by separate private entities. None are providing much transparency into how they select numbers to be added to these lists. However, several do give individuals the ability to flag calls as unwanted spam or scam calls from their mobile device as one possible method for a number to be blocked.
In general, these two steps can be followed to resolve this issue:Alternatively, the following information is available from various carriers and phone and OS manufacturers:
T-Mobile
What if a call is misidentified and is either not a scammer or they are a scammer?
Verizon*
We get many complaints about unwanted computerized calls, and we get it - no one likes robocalls. To help you identify them, we've added a new Spam Alerts feature to your home phone's Caller ID. Your Caller ID will show "SPAM?" before the caller's name that has been identified* as a possible unsolicited call.
*A complex and always-improving algorithm is used to determine which calls match the SPAM criteria. While we're focused on identifying and alerting you to these types of calls as much as possible, you may still receive unsolicited calls from spammers/scammers as these calls will not be blocked automatically. You still choose which calls you to want to answer and which ones you don't. Coming Soon: To report numbers that you believe should be listed as spam or incorrectly labeled as such, please visit verizon.com/SpamAlerts.

Apple
Apple does not advise of a similar form or way to report false flagging of numbers.
In addition to the scam detection features offered directly by carriers and phone manufacturers, there are numerous 3rd party apps that users can download on both iPhones and Android devices to flag and/or block potential scam calls. There is no way to “audit” or verify if a number is on one of these numerous spam lists. Suppose a legitimate number is blocked as spam or scam.
In that case, it may be advisable to deactivate that number and purchase a new number if the above options did not resolve the situation.
