  • Tyler
  • Longview
  • Sherman
  • Texarkana

  • Paris
  • Corsicana

 For more information on local area codes and service regions, visit the Public Utility Commission of Texas website or  1701 N. Congress Avenue, Austin, TX 78701.

What Time Zone is 430 Area Code in the USA?

The 430 area code is situated within the Central Time Zone (CT). This time zone aligns with most of Texas, except for some western regions of the state. Standard time in the Central Time Zone is referred to as Central Standard Time (CST), which observes an offset of UTC-6. During Daylight Saving Time, the offset changes to UTC-5, referred to as Central Daylight Time (CDT). Individuals living in or calling area code 430 should make note of these time shifts, generally occurring between early spring and early fall, in order to correctly schedule interstate communications.

History of the 430 Area Code

Area code 430 was officially introduced in 2003 as part of the North American Numbering Plan to help address the increasing demand for new telephone numbers within northeastern Texas. Prior to this, area code 903 served much of the region and experienced a surge in usage due to the rising popularity of mobile phones, internet connections, and other communication services.

The overlay of 430 onto the existing 903 area was implemented to reduce the inconvenience that would have resulted from splitting existing service areas. As a result, residents within the overlay region could keep their existing phone numbers while newly issued numbers would typically include the 430 prefix. 

Demand for new telephone numbers in Texas remains strong, prompting ongoing monitoring by state regulators, such as the Public Utility Commission of Texas. 

How Many People Use the 430 Area Code?

Currently, area code 430 serves fewer than one hundred thousand people. But Northeast Texas is experiencing steady growth due to factors such as:

  • Economic development in major urban centers (e.g., Longview and Texarkana)
  • New housing developments in expanding cities
  • Increasing need for wireless phone connections and broadband services

According to the United States Census Bureau, much of Texas's growth stems from business expansion and new residents moving into the state. Consequently, the number of subscribers using the 430 area code is constantly growing. 

Is the 430 Area Code Toll-Free?

Area code 430 is not a toll-free code. It is a standard geographic area code that designates telephone service for the northeastern region of Texas. Typical call charges depend on the caller’s telephone plan, and calls may incur local or long-distance fees. Toll-free numbers in the United States customarily begin with prefixes such as 800, 888, 877, 866, 855, 844, or 833, which are different from 430.

For more details on rules on toll-free communications can consult  the Federal Communications Commission (FCC), or 45 L Street NE, Washington, DC 20554.

For more details on fee structures and regulations, individuals can contact the website of the Public Utility Commission of Texas or  1701 N. Congress Avenue, Austin, TX 78701.
