Area codes are part of our everyday lives, yet most of us never think twice about them—until we see a new one pop up. One of the newest numbers you might notice is the 943 area code. But where is it? Who uses it? And why was it created? In this complete guide, we’ll explain everything you need to know about area code 943 in the United States, including its location, history, and how to call it. Whether you live in Texas or just got a call from this number, you’ll have all the answers here.
What Area Code Is 943?
The 943 area code is a telephone area code in the United States that serves parts of Texas. It’s what we call an overlay area code, which means it was added to cover the same geographic region as existing area codes when phone numbers in that area started running out.
So, if you see a number starting with 943, you can be almost certain that it’s from Texas. More specifically, the 943 area code location is within the Dallas–Fort Worth metroplex and surrounding counties, sharing space with other area codes like 817 and 682.
This new code helps ensure that there are enough phone numbers for everyone—businesses, residents, cell phones, landlines, and even internet phone services.
Where Is Area Code 943 Used?
The 943 code is used in North Texas, particularly in the areas covered by the 817 and 682 area codes. This includes Fort Worth and nearby suburbs, along with surrounding counties. If you live in or around this region, you might get a 943 phone number when signing up for a new phone line or switching carriers.
Because it’s an overlay, 943 doesn’t replace older numbers. People who already had 817 or 682 will keep them—new lines just get the fresh 943 prefix. This is common across the U.S. when regions run out of available phone numbers.
Cities With 943 Area Code
Area code 943 is tied to a vibrant part of Texas with a growing population and booming economy. Some of the cities that use the 943 code include:

- Fort Worth
- Arlington
- Grapevine
- Mansfield
- North Richland Hills
- Bedford
- Keller
- Hurst
- Euless
- Weatherford
- Burleson
- Cleburne
These cities are part of the Dallas–Fort Worth metro area, one of the largest urban regions in the U.S., so it’s no surprise they need more phone numbers.
Counties That Use 943
Area code 943 stretches across several counties in North Texas, including:
- Tarrant County
- Parker County
- Johnson County
- Denton County (parts)
- Wise County (parts)
Each county shares the 943 code with 817 and 682, meaning residents could have any of the three.
New Calls With 943 Code
If you’re getting a call from a 943 phone number, it’s most likely a new number assigned after the overlay went into effect. Businesses, mobile phone carriers, and even VOIP services now issue 943 numbers.
However, just like with any area code, scammers sometimes use 943 to make spam calls or robocalls. If you don’t recognize the caller, it’s a good idea to look up the number before answering.
Why Was Area Code 943 Created?
Texas is growing fast—especially in the Dallas–Fort Worth area. More people means more phones, and more phones mean the existing numbers run out. When all possible 817 and 682 numbers were close to being used up, the North American Numbering Plan Administrator (NANPA) approved the addition of 943 as an overlay.
This way, nobody has to change their old number, but new numbers can keep being issued without delays.
When Did Area Code 943 Start?
The 943 area code start date was January 2021. From that time onward, new phone numbers in the covered region could be assigned the 943 prefix.
Before it launched, phone companies had to prepare by updating dialing systems and letting customers know about the change.
How to Call a 943 Number
Calling a 943 number in Texas is simple—you just dial the full 10-digit phone number, including the area code. For example:
CopyEdit
943-XXX-XXXX
Since it’s an overlay, even local calls require 10-digit dialing in the 943 region. This is standard in most parts of the U.S. now.
Calling 943 Numbers in the U.S.
If you’re in the U.S. and calling a 943 number, just use the regular 10-digit dialing format. You don’t need to add the country code unless you’re calling from abroad.

Calling 943 Numbers From Other Countries
To call a 943 number from outside the U.S., you’ll need to use the U.S. country code +1, followed by the area code and phone number. For example:
diff
CopyEdit
+1 943 XXX XXXX
Keep in mind that international calling rates may apply depending on your phone plan.
