What area code is 945? The 945 area code is the newest local area code in the Dallas, Texas metropolitan area. It went into service on January 15, 2021, to meet the increased demand for phone lines in Dallas and its surrounding communities.

Area code 945 serves as a code overlay of the 214 area code geographic region alongside 972 and 469, part of the North American Numbering Plan Administrator (NANPA) system.

By writing this guide, we aim to provide our readers with a complete overview of the 945 area code in Dallas.

It explores its predecessors, the Texas cities and counties it covers, and the most prominent carriers responsible for administering 945 phone lines to North Texas businesses and consumers alike.

So, let’s begin by examining the geographical location aspect as we answer the question: Where is the 945 area code?

Where is Area Code 945 Located?

The new 945 area code serves Dallas, Texas, and its surrounding communities. While Dallas County is the heart of its territory, it extends into Collin, Denton, and portions of Fannin, Hunt, Johnson, Kaufman, and Tarrant counties.

These communities comprise a diverse region comprising commercial, industrial, and residential areas.

The three other area codes serving phone line customers in the same region include:

• 214 (The original area code assigned to North Texas)
• 972
• 469

These four area codes form a complex area code overlay system, a strategy used to combat phone line exhaustion and make more phone numbers available to customers.

Callers must dial the complete 10-digit number (3-digit area code + 7-digit telephone number) to reach these lines.

What time zone is area code 945 in?

945 Area Code Time Zone

The 945 area code is in the Central Time Zone (CT). This zone is commonly referred to as American/Chicago time.

It is UTC-6 during Standard Time (from the second Sunday in November to the second Sunday in March) and UTC-5 during Daylight Saving Time (from the second Sunday in March to the first Sunday in November).

UTC stands for Coordinated Universal Time. UTC-0 is the local time of Greenwich, England, and the Prime Meridian, which are six hours ahead of the time in the 945 area code during Standard Time in the United States.

Higher Risk of Area Code 945 Scams and Spam Messages

Since the NANPA recently rolled out the 945 area code, telephone numbers with this area code are more likely to be used for fraudulent activities than those with older area codes.

The freshness of the 945 phone lines facilitates scammers using recycled phone numbers, as carriers will most likely not have flagged them as scams or telemarketers.

That means you won’t get the benefit of the caller ID displaying a “scam likely” label for 945 phone numbers, even when it is a scam operation calling you.

Keep that in mind the next time you get a phone call or spam text message from a 945 area code out of the blue, especially if your phone number has a Dallas area code.

Scammers like to try to appear local by using software that allows them to use a local area code phone number in a completely different location.

People are naturally more likely to answer a call from a local number than one from a foreign country, and unfortunately, telemarketers and fraudsters from around the world use that to their advantage.

945 Area Code Prefix System

The 945 area code uses a prefix system to organize and manage phone numbers within the region. Each prefix, also known as a central office code or exchange code, consists of three digits and follows the area code in a phone number.

This system is what makes telephone numbers unique and efficiently managed. Here’s how the prefix system works for the 945 area code:

Structure of a 10-digit Phone Number

A typical phone number in the 945 area code follows the format: (945) NXX-XXXX.

• The first three digits (945) represent the area code,
• The next three digits NXX are the prefix,
• and the final four digits XXXX are the line number.

Assignment of Prefixes

Prefixes are assigned to specific geographic areas and service providers within the 945 area code region. Since the area code is new, only 168 prefixes are assigned, about one-fifth of its total possible capacity. Dallas’ original 214 area code has 788 assigned prefixes.

Examples of 945 Area Code Prefixes

Below, we list a few examples of actual prefixes assigned within the 945 area code:

• 945-229: Assigned to CallWorks in Dallas.
• 945-425: Assigned to Onvoy in Lewisville.
• 945-312: Assigned to Verizon Wireless in Waxahachie.

Importance of the Prefix System

The prefix system is crucial for managing many millions (eventually) of phone numbers within the 945 area code. It drastically increases the number of available phone lines within a single area code.

Without it, there would need to be significantly more area codes within the city of Dallas alone, which could get confusing fast and negatively affect the efficiency of local call routing.

By having a basic understanding of how the prefix system works, residents and businesses in the 945 area code region can better appreciate how their phone numbers are organized and managed.

This system does more than facilitate reliable and efficient telecommunications services in the Dallas metropolitan area. It ensures the police pickup when you dial 911.
