Prefix Blocks (NPA-NXX)

159 active prefixes in this area code, assigned as 1,418 thousands-blocks — pooling splits one prefix across several carriers, so each block is listed separately with the rate centre it is homed to, its carrier of record, and the switch that serves it.

About Area Code 743

Area code 743 is a North American Numbering Plan (NANP) telephone area code assigned to North Carolina, United States. It is one of 10 area codes serving North Carolina. As population and demand for phone numbers grew, the region was divided into multiple numbering plan areas to avoid exhausting the available 7-digit number pool.

Is 743 a valid area code?

Yes. 743 is an active North American Numbering Plan (NANP) area code, currently assigned to North Carolina, United States. It is safe to answer or dial calls using this area code.

Where is area code 743?

Area code 743 covers 66 cities and communities in North Carolina, including Advance, Anderson, Asheboro, Badin Lake, Boonville, and 61 more localities. This is based on telephone company rate center data — the geographic areas carriers use to determine local calling boundaries and to assign numbers when a business or individual requests a phone number in a specific city.

What time zone is area code 743?

All numbers in the 743 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 743 number from a different time zone, check the current local time above to avoid calling outside of business hours.

How do I dial a 743 number?

From within North Carolina, dial the 7-digit local number directly if calling within the same rate center, or dial 1 + 743 + 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 1 743 XXX XXXX. The country code for both the United States and Canada in NANP is +1.

Formatting 743 phone numbers

Format 743 numbers using E.164 notation as required by RFC 3966: prefix with +1 and omit dashes and parentheses (e.g., +17435550100). This format ensures tel: links work correctly on all mobile browsers and VoIP apps. See the tel: URI formatting guide for complete examples.
