Texas – New 281/346/713/832/621 area code overlay

To ensure a continuing supply of telephone numbers, the Public Utility Commission of Texas has approved an all-services overlay for the 281/346/713/832 area code overlay region. The 281/346/713/832 NPA serves the greater Houston metropolitan area and surrounding suburban cities such as Baytown, League City, Missouri City, Pasadena, Pearland, Sugar Land, The Woodlands and many other smaller communities. The new 621 area code will serve the same geographic area currently served by the 281/346/713/832 area codes.

Beginning January 23, 2025, customers in the 281/346/713/832 area code overlay region may be assigned a number in the new 621 area code when they request new service or an additional line. Customers receiving the 621 area code will be required to dial 10 digits for all local calls, just as customers with telephone numbers from the 281/346/713/832 area codes do today. Mobile phone customers receiving 621 numbers may dial either 10 digits or 1+10 digits.
