Mandatory 10-digit dialing begins May 14 for new 540/826 overlay area code

Mandatory 10-digit dialing (3-digit area code + the 7-digit telephone number) begins May 14 for Virginians living in the 540 area code region.

Local calls made with just seven digits will not be connected. This is the second step in a June 2020 relief plan approved by the State Corporation Commission to phase in the new 826 area code.

The 540 area code encompasses the northwestern and southwestern portions of Virginia; some of the larger cities include Blacksburg, Christiansburg, Culpeper, Fredericksburg, Front Royal, Harrisonburg, Radford, Roanoke, Salem, Staunton, Waynesboro and Winchester.

In the coming months, the inventory of available phone numbers with “540” as the area code is expected to run out. The SCC approved an overlay, which is the addition of another area code (826) to the same geographic region served by an existing area code (540). Beginning June 14, 2022, new telephone lines or services may be assigned numbers using the new 826 area code.

The good news: residents and businesses that already have phone numbers will get to keep them. No one’s 540 phone number will change.

Alarm, security, and elevator services and equipment currently located in the 540 area code and programmed to dial only seven digits must be updated or reprogrammed to dial the area code + telephone number for all calls in the 540 area code.
