Code-holder of record: LEVEL 3 COMMUNICATIONS, LLC - AL (OCN 5255), assigned December 9, 2015. The prefix is pooled: its ten thousands-blocks can be shared among several carriers, so different 205-730 numbers may be served by different companies.

Caller ID showing 205-730 is not proof the call came from Birmingham: 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.
