213-370 identifies a block of numbers in Los Angeles:da 01, CA, within the 213 area code. Every US prefix is tied to exactly one rate center; this one is Los Angeles:da 01.

The rate center lies in the Los Angeles-Long Beach-Anaheim, CA Metropolitan Statistical Area. The serving LATA is 730. Local time follows the Pacific zone.

Treat the on-screen number as a hint, not evidence — 213-370 can be spoofed like any US prefix. If a call feels off, verify through an official callback number and file a complaint with the FCC or FTC.

NANPA's central-office code records list VONAGE AMERICA LLC (OCN 197D) as the code holder, assigned November 26, 2018. Because 213-370 participates in thousands-block pooling, individual 1,000-number blocks may belong to other carriers than the code holder.
