The story of Houston's area codes is a story of relentless growth. From a single-code city to a three-overlay metropolitan area, Houston's telephone numbering history mirrors its population and economic explosion.

• 1947: All of Texas assigned area code 512.
• 1959: 713 split from 512, assigned to Houston and Southeast Texas.
• 1983: 409 split from 713, taking Beaumont and the Golden Triangle.
• 1995: 281 introduced as the first Houston overlay, covering suburbs as 713 neared exhaustion.
• 2000: 832 introduced on January 1 as the second Houston overlay alongside 713 and 281.
• 2013: 346 introduced as the fourth Houston-area overlay as 832 and 281 neared exhaustion.

Houston's extraordinary growth — fueled by energy, healthcare, aerospace (NASA Johnson Space Center), and port trade — drove the need for four overlapping area codes across the metro.

Greater Houston is the energy capital of the world and home to a diverse economy that extends well beyond oil and gas. The Houston metro's GDP exceeds $500 billion, ranking it among the top 10 US metro economies.

832 vs 713 vs 281 vs 346 — Which Houston Code to Choose?

• 713 — the original Houston code, strongest brand recognition for central Houston businesses
• 281 — first overlay (1995), suburban Houston association
• 832 — second overlay (2000), modern Houston — equally valid for any Houston business
• 346 — newest overlay (2013), still carries slight 'new number' stigma for some clients

For most new Houston businesses, 832 or 713 are the strongest choices. Both signal genuine Houston presence without the 'brand new number' association of 346.
