History of Area Code 346

Area code 346 was established in 2014 as an overlay for the existing Houston-area numbering plan. The Texas Public Utility Commission approved it to serve the same geographic region already using area codes 713, 281, and 832. The new code was added because the Houston region needed more phone numbers.

Area code 346 officially entered service on July 1, 2014. It did not replace older area codes or split the region into smaller pieces. Instead, it joined the existing overlay system, which means new phone numbers in the same area can use 346, 713, 281, or 832. Because of this overlay system, 10-digit dialing became necessary throughout the area.
