The assigned code holder is LEVEL 3 COMMUNICATIONS, LLC - RI, operating company number 4016, assigned January 3, 2006. This is a pooled prefix — expect numbers within it to be split across more than one carrier in 1,000-number blocks.

Caller ID showing 401-626 is not proof the call came from Providence: 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.
