This guide provides a detailed overview of its geographic coverage, dialing patterns, regulatory details, and practical implications for developers and businesses. You'll gain a thorough understanding of how Area Code 540 functions within the broader telecommunications landscape.

Geographic Coverage: Pinpointing the 540 Region

Area Code 540 covers a diverse range of communities in western Virginia, playing a vital role in local and regional communication networks. You'll find it essential to understand this coverage if your business or application interacts with users in this area.

Core Service Area

Primary Cities: Blacksburg, Roanoke, Harrisonburg, Winchester, and Fredericksburg
State: Virginia
Country: United States
Approximate Center (Latitude/Longitude): 37.22957° N, -80.41394° W

This central location, while helpful for general understanding, doesn't fully represent the extensive reach of the 540 area code. The actual coverage extends across numerous counties and smaller towns, creating a complex network of interconnected communities.

Detailed County Coverage

Area Code 540 encompasses a significant portion of Virginia, including (but not limited to) the following counties: Alleghany, Augusta, Bath, Botetourt, Clarke, Craig, Culpeper, Fauquier, Floyd, Franklin, Frederick, Giles, Highland, King George, Louisa, Madison, Montgomery, Orange, Page, Pulaski, Rappahannock, Roanoke, Rockingham, Rockbridge, Shenandoah, Spotsylvania, Stafford, and Warren. Additionally, parts of Bedford County and a small section of Albemarle County (specifically Afton and Greenwood, served by Verizon landlines) fall within the 540 area code. Note that western Loudoun County is also partially covered by 540, while the majority of the county uses area codes 703 and 571. This overlapping coverage can be important for businesses targeting specific demographics within these counties.

Dialing Patterns: Connecting with 540 Numbers

Understanding the dialing patterns for Area Code 540 is essential for developers building applications that handle phone numbers or for businesses communicating with customers in this region. You'll need to ensure your systems correctly interpret and process these patterns.

Standard and Permissive Dialing

The following table summarizes the standard and permissive dialing patterns for Area Code 540:

Dialing Type	Local Call (within 540)	Toll Call (outside 540)
Standard HNPA	10D (10 Digits)	1+10D
Standard FNPA	10D (10 Digits)	1+10D
Standard Operator Assisted	0+10D	N/A
Permissive HNPA	1+10D	1+10D
Permissive FNPA	1+10D	1+10D

HNPA: Home Numbering Plan Area (the caller's area code) FNPA: Foreign Numbering Plan Area (the called party's area code) 10D: 10 Digits (area code + 7-digit number)

These patterns dictate how calls are routed and billed. It's crucial to note that 10-digit dialing (including the area code) is now mandatory within the 540 area code due to the introduction of the overlay area code 826 in 2022. This overlay means that both 540 and 826 serve the same geographic region. You should ensure your systems are updated to reflect this mandatory 10-digit dialing requirement.

International Dialing

For international calls to Area Code 540, the caller must dial their country's international access code (e.g., 011 from the US), followed by 1 (the US country code), the 540 area code, and finally, the 7-digit local number. Your applications should handle these international dialing patterns correctly to ensure global connectivity.

Telecommunications and Regulatory Information: The Legal Landscape

Area Code 540 falls under the jurisdiction of the North American Numbering Plan Administration (NANPA), which ensures efficient number allocation and management. You'll find this information relevant if you're developing telecommunications applications or services within this area.

Regulatory Oversight

NANPA, overseen by the Federal Communications Commission (FCC), manages the allocation of area codes and phone numbers across North America. This centralized administration ensures consistency and prevents conflicts in numbering. The Virginia State Corporation Commission also plays a role in regulating telecommunications services within the state, including those within Area Code 540. As noted in the provided additional context, localities in Virginia can also provide telecommunications services, subject to obtaining a certificate and complying with regulations outlined in § 15.2-2160 of the Virginia Code. This allows for a mix of public and private telecommunications providers in the area.

Carrier Services and Number Availability

Multiple carriers operate within Area Code 540, offering a variety of services to consumers and businesses. New numbers are regularly allocated to meet the ongoing demand. This competitive landscape provides you with choices when selecting a telecommunications provider for your business or application.

The 826 Overlay: A Key Development

As mentioned earlier, Area Code 826 was introduced as an overlay to 540 in May 2022. This overlay was implemented due to the projected exhaustion of available phone numbers within the 540 area code. The introduction of 826 highlights the continued growth and demand for telecommunications services in the region. You should be aware of this overlay when designing applications or services that interact with phone numbers in this area.
