Area code 713 – Texas

713 is one of the original area codes, in service across Texas since 1947. All but a handful of its 786 number blocks are allocated (785 of 786), so it is effectively exhausted. AT&T holds 68.9% of those blocks, which is unusually concentrated for a US area code. It shares its geography with overlay codes 281, 346, 621, 832, so local calls take all ten digits. 881 FTC complaints named a 713 caller ID in the 33 days to 30 October 2026, putting it 67th of 422 codes with five or more complaints.

Can I still get a 713 number?

Not by itself. 713 drew 881 FTC complaints in the 33 days to 30 October 2026, 67th of 422 ranked codes – mid-pack or lower. Spam callers spoof caller IDs, so the only useful check is the full number. The most reported category here is “Other”.
