Exploring the 458 Area Code: A Comprehensive Guide to the DFW Metroplex

The 458 area code is a relatively new addition to the Dallas-Fort Worth Metroplex, having been introduced in 2019 to overlay the existing 972 area code. It serves the rapidly growing communities in the northern suburbs of Dallas, including areas such as Plano, Frisco, and McKinney.

Understanding the 458 Area Code

The 458 area code is a local calling area that includes portions of Collin, Dallas, Denton, and Grayson counties. It was created in response to the increasing demand for telephone numbers in the Metroplex, which has seen a significant population growth in recent years.

Telephone Numbering Plan

Telephone numbers in the 458 area code follow a standard 10-digit format:

• The first three digits (NPA, or National Prefix) are 458.
• The next three digits (NXX, or Central Office Code) identify the specific geographic location and telephone service provider.
• The last four digits (LN, or Line Number) are unique to each individual telephone line.

Coverage Area

The 458 area code primarily covers the following areas:

• Collin County: Allen, Fairview, Lucas, McKinney, Murphy, Plano, Princeton, Prosper, and Wylie.
• Dallas County: Addison, Carrollton, Farmers Branch, and Richardson.
• Denton County: Little Elm and The Colony.
• Grayson County: Sherman and Denison.

Statistics and Demographics

According to the United States Census Bureau, the population of the 458 area code coverage area is estimated to be:

• Collin County: 1,094,793
• Dallas County: 2,558,950
• Denton County: 955,593
• Grayson County: 142,050

The Metroplex is a major economic hub in the United States, with industries such as technology, healthcare, telecommunications, and finance playing a significant role. The area has also seen a steady influx of new residents and businesses in recent years, contributing to its rapid growth.

Initially, calls were routed to both the 458 and 972 area codes, giving customers time to update their records and contacts.
