What Time Zone Is 817 Area Code in the USA?

The 817 area code is situated in the Central Time Zone (CT). In accordance with state and federal guidelines, communities within this region observe Daylight Saving Time (DST).

During Central Standard Time (CST), the offset is six hours behind Coordinated Universal Time (UTC-6), and during Central Daylight Time (CDT), the offset is five hours behind Coordinated Universal Time (UTC-5).

History of the 817 Area Code

The 817 area code was established in 1953 as part of the nationwide telephone numbering plan implemented to meet increasing post-World War II demand. Originally formed from a larger area code, 817 was introduced to better serve the growing population and economy in the north-central section of Texas. Over time, demand for telephone numbers continued to rise, leading to additional adjustments. These changes included:

  • Splits from the original 817 region that created new area codes such as 254 and 940.
  • The overlay of Area Code 682 in 2000 to ensure sufficient numbering resources.

Regulatory oversight of these area code adjustments falls under the purview of the Federal Communications Commission and the Public Utility Commission of Texas. For official guidelines and regulations, see the federal telephone regulations.

How Many People Use the 817 Area Code?

Area Code 817 serves a populous region anchored by Fort Worth and its adjacent municipalities. According to population statistics from national and regional data, millions of residents and businesses rely on 817. By covering much of Tarrant County, as well as parts of Parker, Johnson, and other counties, this area code meets the communications needs of a varied and expanding citizenry.

Key population aspects within this area code include:

  • Approximately 2 to 3 million people living within Tarrant County and surrounding areas.
  • Significant commercial and residential growth over the past two decades in communities such as Arlington and North Richland Hills.
  • Ongoing development, further stressing the demand for new phone numbers.

It is a vital resource for civic agencies, including the City of Fort Worth City Hall, 200 Texas St., Fort Worth, TX 76102, which coordinates many municipal services for residents and businesses alike.

Is the 817 Area Code Toll-Free?

The 817 area code is a geographic area code tied to specific regions in Texas rather than a toll-free designation. Callers should note:

  • Calls within the local calling area generally incur standard local rates.

  • This area code should not be confused with toll-free prefixes, such as 800, 888, 877, 866, 855, 844, or 833, which are assigned for nationwide toll-free services.

Users seeking additional clarification on call rates or special calling rules can refer to the State transportation guidelines for any phone service details made available through local facilities and licensing offices. Any concerns regarding phone bill regulations or consumer protections may be directed to the Public Utility Commission of Texas or to local government help desks in the counties served by Area Code 817.
