The 430 area code serves northeastern Texas, including cities like Tyler, Longview, and Sherman. It was created as an overlay for the existing 903 area code to accommodate the growing demand for phone numbers in the region.
This article provides a complete guide to the 430 area code, covering its exact location, the main cities it includes, its history, and how to stay safe from potential scams.
Where is the 430 Area Code Located?
The 430 area code is exclusively located in the northeastern part of the state of Texas. It’s not a standalone code but functions as an “overlay” for the 903 area code. This means that both 430 and 903 numbers exist in the same geographic area. Because of this overlay system, 10-digit dialing (area code + seven-digit number) is mandatory for all local calls within this region.
The area covers a significant portion of the state, stretching from the suburbs of the Dallas-Fort Worth metroplex eastward to the borders of Arkansas and Louisiana.

What Cities Use the 430 Area Code?
This area code covers a mix of bustling cities and smaller towns. If you have a phone number with a 430 prefix, it’s likely based in or around one of the following major population centers:
- Tyler: Known as the Rose Capital of America.
- Longview: A major hub for East Texas.
- Sherman: Located north of the Dallas-Fort Worth area.

History and Purpose of Area Code 430
The original area code for this entire region was 903, established in 1990. Due to the rapid increase in population and the proliferation of cell phones and pagers, the North American Numbering Plan Administration (NANPA) determined that the 903 area code was running out of available numbers.
To solve this, the 430 area code was officially introduced on February 15, 2003. Instead of splitting the region into two separate area codes, a more modern overlay plan was implemented. This allowed existing 903 numbers to remain unchanged while all new numbers assigned in the area could be either 903 or 430.
Is the 430 Area Code a Scam Risk?
Any area code can be used by scammers for robocalls and fraudulent activities. However, the 430 area code itself is not known for being a particularly high-risk or scam-prone code. It is a standard geographic area code assigned to a legitimate region in the United States.
Regardless of the area code, it’s always wise to be cautious. Follow these simple tips to protect yourself:
- Don’t answer calls from numbers you don’t recognize.
- Never give out personal information like your Social Security number or bank details over the phone.
- Be wary of callers creating a sense of urgency or threatening you.
- If a call sounds suspicious, hang up immediately.
