History of Area Code 346
The North American Numbering Plan Administration introduced the 346 area code to Houston as an overlay on April 27, 2013, and has been implemented since July 1, 2014. This code is the 26th local code for Texas and the 376th area code in service. It was added to the existing 713, 281, and 832 codes as an overlay.
The NANPA created the new code to meet Houston’s growing demand for phone numbers. The addition of 346 ensured a continuous supply of phone numbers for the rapidly growing population and businesses.
