The 513-220 prefix belongs to area code 513 and is anchored to the Cincinnati rate center (OH). In NANP terms, the prefix — or NXX — determines the rate center a number is billed against.

Cincinnati is part of the Cincinnati, OH-KY-IN Metropolitan Statistical Area. For routing purposes it sits in LATA 922. Numbers here keep Eastern time.

NANPA's central-office code records list SKYE TELECOM LLC DBA SKYETEL (OCN 622J) as the code holder, assigned March 10, 2023. Because 513-220 participates in thousands-block pooling, individual 1,000-number blocks may belong to other carriers than the code holder.

Caller ID showing 513-220 is not proof the call came from Cincinnati: 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.
