713 area code
Houston and surrounding metropolitan communities.
713 is part of Houston's overlay complex with 281, 346, 621 and 832. A Houston-area customer can therefore have one of several prefixes. The older idea that 713 always distinguishes an inner-city address from a suburban one is not reliable for routing today's calls.

Questions about 713
Is 621 a Houston-area code too?
Yes. 621 is now part of the Houston overlay complex. Keep all ten digits when recording a Houston callback number rather than assuming 713 or 281.
Is a 713 call safe to answer?
The 713 prefix identifies a numbering region, not a caller's identity or trustworthiness. Verify an unexpected request by contacting the organization through a number you already know.
Can I get a 713 business number?
Search the available numbers in VeraDial. Inventory changes, so a 713 number is not guaranteed. You can also keep your current carrier number and forward voice calls to a VeraDial line; existing texts stay with your carrier.
