Prefix 713-836 — Houston, TX
713-836 identifies a block of numbers in Houston, TX, within the 713 area code. Every US prefix is tied to exactly one rate center; this one is Houston.
The rate center lies in the Houston-Pasadena-The Woodlands, TX Metropolitan Statistical Area. The serving LATA is 560. Local time follows the Central zone.
Treat the on-screen number as a hint, not evidence — 713-836 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 SOUTHWESTERN BELL (OCN 9533) as the code holder, assigned December 16, 2010. Because 713-836 participates in thousands-block pooling, individual 1,000-number blocks may belong to other carriers than the code holder.
