More than one of these codes covers 73 of the 254 counties in Texas, and one county is covered by 7 of them. Each card counts the people inside that code's own boundary at the 2020 census. Adding all 29 gives 77,296,039, against the 29,145,505 the same census counts in those counties, because 48,150,534 residents fall inside more than one code.

How many phone prefixes does Texas use?
The area codes in Texas hold 15,029 assigned prefixes between them, listed under 191 distinct carrier names. A prefix is the three digits after the area code, and NANPA assigns each one to a single carrier. One of the 29 codes here — 621 — is newer than the NANPA extract behind these numbers, so its prefixes are not counted above.
