Area code 540 covers 117 rate centers across Virginia. Communities served include Alum Ridge, Ballard, Basye, Bedford, Bent Mountain, and 112 more localities. Rate centers are the geographic building blocks telephone carriers use to determine local calling boundaries and to assign numbers when a business or individual requests a phone number in a specific city.
All numbers in the 540 area code observe Eastern Time (IANA timezone: America/New_York). Eastern Time is UTC−5 in winter (EST) and UTC−4 in summer (EDT). When placing a call to a 540 number from a different time zone, check the current local time above to avoid calling outside of business hours.
From within Virginia, dial the 7-digit local number directly if calling within the same rate center, or dial 1 + 540 + 7-digit number for long-distance calls within North America. From outside the US or Canada, dial your country's international exit code followed by 1 540 XXX XXXX. The country code for both the United States and Canada in NANP is +1.
Format 540 numbers using E.164 notation as required by RFC 3966: prefix with +1 and omit dashes and parentheses (e.g., +15405550100). This format ensures tel: links work correctly on all mobile browsers and VoIP apps. See the tel: URI formatting guide for complete examples.
