Prefix 401-606 — Providence, RI

NANPA CO code assignment, current as of July 28, 2026.

The 401-606 prefix belongs to area code 401 and is anchored to the Providence rate center (RI). In NANP terms, the prefix — or NXX — determines the rate center a number is billed against.

Providence is part of the Providence-Warwick, RI-MA Metropolitan Statistical Area. For routing purposes it sits in LATA 130. Numbers here keep Eastern time.

The assigned code holder is PAETEC ITEL, LLC, operating company number 829J, assigned April 18, 2012. 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 401-606 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.
