Code-holder of record: AERIAL COMMUNICATIONS, INC. (OCN 6701), assigned June 24, 2019. The prefix is pooled: its ten thousands-blocks can be shared among several carriers, so different 612-433 numbers may be served by different companies.

Caller ID showing 612-433 is not proof the call came from Twin Cities: spoofing and porting both detach numbers from their origin. To verify a caller, hang up and dial the organization's published number, and report suspicious calls to the FTC.
