It serves the city of Houston and inner-loop areas including Bellaire, West University Place, and parts of Pasadena, and is a local (non-toll-free) area code in the Central Time Zone.
713 originally covered all of southeast Texas. As Houston grew into the fourth-largest city in the country, splits and overlays added 409 (1983) and 281 (1996) to handle suburb demand. Subsequent overlays 832 (1999) and 346 (2014) brought the inner Houston area into a four-code overlay complex (713/281/832/346). Despite the multiple overlays, a 713 number remains the heritage signal for established Houston businesses, energy companies, and medical institutions.

LOCAL, BUT NOT ENOUGH
Why does Houston send unknown 713 calls to voicemail?
Modern call screening is unforgiving. An unfamiliar 713 line gets the same treatment as a robocall unless it's tied to a verified business profile, which is why Bayou City customers answer registered numbers 3.4x more often.
