| Overlays: An area code overlay happens when multiple codes cover the same geographic region.

| Prefix Assignment: There are 800 possible prefixes per Area Code. This shows how much of those prefixes have been assigned to a telcom company. A high percentage of assignment shows that numbers are running out and close to being exhausted. When this occurs, Overlays are created to increase how many numbers are available for this geographic area. A geographic region can also be "split" into smaller geographic regions. One region retains the existing area code with a new code created for the other region. | 97.0% [See More] |

NANPA (North American Numbering Plan Administrator) put this area code into service prior to January, 1, 1947 (when data tracking began)
On Friday, August 19, 1994, NANPA announced Area Code 281 as an overlay relief and put it into service on Saturday, November 2, 1996. On Saturday, April 27, 2013, NANPA announced Area Code 346 as an overlay relief and put it into service on Tuesday, July 1, 2014. On Thursday, October 15, 1998, NANPA announced Area Code 832 as an overlay relief and put it into service on Saturday, January 16, 1999.
776 Prefixes are active and currently being assigned. Of the total active prefixes, 582 (75.0%) are for Landlines, 193 (24.9%) are for Wireless numbers, and 1 (0.13%) have unknown type reservations. 24 Prefixes (3.0%) remain inactive and do not have assignments. They assigned the first prefix on Friday, February 4, 1994 and the last prefix on Tuesday, July 19, 2022.
This Area Code is not in jeopardy, so it will not run out of numbers before a change can be made. NANPA has projected that the availability of numbers in Area Code 713 may run out soon (or its parent already has) and has put it into relief planning status.

Prefix Assignment & Usage for 713
Prefix Assignment
Usage Type
Assignment shows how many of the 800 Prefixes (NXXs) possible have been assigned to a telcom provider. Once assigned, that provider can start issuing numbers for that prefix. Only Prefixes from 200-999 are possible.
A high percentage of assignments indicate that the number availability in this area is exhausting and may soon run out. Overlays and Splits will add more number options to alleviate the shortage of the parent area code.
A Split can also happen where the geographic region is split into two smaller parts. While a new code is made to cover a different region, one area code remains unchanged.
Usage shows how the prefixes are designated for use by the telcom provider, either landline or wireless. Telcoms can sub-license out parts of the prefixes to other carriers who may use it for any purpose needed. For example, a carrier might license the 2000 block of 713-400-2XXX. Even if the 400 Prefix is designated as landline, they can use these numbers for wireless use.
Number Portability from the Telecommunications Act of 1996 has also made it so individuals can take a landline number and move to a wireless carrier (and vice versus). While Usage data is still helpful, its utility is fading with "cord cutting" and the shift from landline to wireless use.
