State and Regional Context
Texas is divided into dozens of area codes because of its massive size and rapidly growing population. San Antonio, located in South-Central Texas, is a primary urban area that has a strong cultural connection to the history, military bases, a growing startup scene, and many large medical centers.
The 210 area code indicates you are either located in this economically vital area or supporting customers from the region. This is especially useful for businesses supporting industry verticals such as real estate, legal services, health care, logistics, and local trades
Nearby Area Codes
As the city grew, the 210 area code couldn’t keep up with demand. That’s why the region now has overlays and neighboring area codes such as:
- 726 – a new area code implemented in 2017 as an overlay for the same geographic area covered by area code 210 to address number exhaustion.
- 832 – covering surrounding rural and suburban areas, including New Braunfels and the Texas Hill Country.
- 512 / 737 – used in nearby Austin, about 80 miles northeast.
If your business routinely works over multiple cities in Texas, understanding these area codes helps you know where your calls are going. It also gives some understanding of the audience you are calling.
210 Area Code Phone Number Format & How to Dial?
A 210 phone number follows the standard 10-digit North American dialing format, with a specific structure: a three-digit area code (210), followed by a three-digit central office code, and a four-digit line number.
(210) 958-3360
Here’s how to dial it based on your location, making sure you use the correct area code and number to reach your intended recipient:
- From within the U.S.: Just dial the 10-digit number, like 210-958-3360
- From outside the U.S.: Dial your country’s exit code (e.g., 00 or +), then the U.S. country code +1, followed by the number: +1 210-958-3360
Due to the overlay of the 726 code, all local calls now require 10-digit dialing with the area code. When you are making a call from within the San Antonio region to a San Antonio number, you also need to include the area code to ensure you are dialing the correct number.
For businesses working with local and out-of-area clients, your dialing systems should be consistent with the 10-digit dialing and area code format, following the correct structure for all phone numbers.

you’re calling into or out of the 210 area code, time zone awareness is a part of good business etiquette.
History Of The 210 Area Code
The 210 area code was assigned in 1992 after being divided from the original bilingual 512 area code, which once encompassed most of Texas. The growth of San Antonio and its businesses with traditional landlines made it a clear decision, one area code would not be sufficient.
But even the new 210 code couldn’t handle the city’s booming population for long. In 1997, it was split again to form:
- 830 – Serving suburban and rural areas around San Antonio
- 956 – Serving the South Texas border region
These changes were necessary due to number exhaustion in the region, as the supply of available phone numbers was rapidly depleting. Overlays and new area codes, such as the 726 overlay added in 2017, were implemented to address the increasing demand for phone numbers and to ensure continued service availability.
Business Scenario and Outlook in the 210 Area Code
San Antonio is quickly emerging as one of the most dynamic business hubs in the U.S., backed by a five-year growth strategy that’s attracting major investments.

Major players like Toyota, Guidehouse, and JCB are building deep roots in the city, solidifying San Antonio’s reputation as a forward-looking, inclusive economy.
