Geographic Coverage & Major Cities
Area code 430 covers Northeast Texas, spanning Smith, Gregg, Bowie, Grayson, and many surrounding counties. Because it is an overlay, it shares the identical footprint of the 903 area code rather than covering a separate zone.
Cities and communities served by the 430 area code include:
- Tyler – the largest city in the region, known as the “Rose Capital of America”
- Longview & Kilgore – East Texas oil-country cities
- Texarkana – the twin city on the Texas-Arkansas state line
- Sherman, Denison, Paris & Marshall – established Northeast Texas communities
As the newer code over the region, 430 numbers are typically assigned to residents and businesses who obtained phone service after the original 903 numbers grew scarce.
A Brief History of Area Code 430
Area code 430 was activated in 2013 as an all-services overlay on the Northeast Texas region. The 903 code was created in 1990 in a split from Dallas’s 214. An overlay adds a second area code across the same geographic area, so existing 903 customers kept their numbers while new lines could be assigned either 903 or 430, under mandatory 10-digit dialing.
Time Zone & Best Time to Call
Numbers in the 430 area code use Central Time (CT). The region observes Daylight Saving Time, shifting from CST (UTC-6) to CDT (UTC-5) between March and November each year.

Is Area Code 430 a Scam? Safety & Protection Tips
Area code 430 is a legitimate Texas area code – a call from it is not fraudulent by default. However, scammers frequently spoof local codes like 430, faking the caller ID so their number appears to come from a trusted Northeast Texas line. Neighbor spoofing, which mimics the first six digits of your own number, is especially common.
