Area code 740

Area code 740 at a glance

Area code 740 is a geographic area code in Ohio, in service since December 6, 1997, according to the North American Numbering Plan Administrator (NANPA). It is an overlay: 740 and 220 cover the same territory, so neighbors on the same street can have different area codes. It is in the Eastern time zone. The places with the most assigned exchanges include Newark, Lancaster, Portsmouth, Zanesville, and Athens. By population, its largest named places are Newark, Jackson, Delaware, Marion, and Lancaster.

How calls are dialed in 740

According to NANPA's dialing-plan data, local calls within 740 are dialed as ten digits (area code plus number) and toll calls as 1 plus ten digits. Because local calls need the area code, business cards, signage and website copy should always show the full ten-digit number. NANPA's dialing-plan note for this code reads: "Carriers must provide permissive 1+10D dialing for Foreign NPA Local Calls in areas where they provide optional EAS. 1+10 digit permissible required excluding CMRS providers"

Carriers with 740 numbers

41 carriers hold the 786 central office codes assigned in 740. Frontier North, INC. - Oh has the most, with 123 (16%). 653 of the codes (83%) are pooled, meaning the code holder shares blocks of 1,000 numbers with other carriers instead of using all 10,000 itself. The code holder is not necessarily the carrier serving a given number today, since numbers can be ported between providers.

Rate centers and towns in 740

NANPA assigns each central office code to a rate center, the local calling area that decides whether a call is local or toll. 740 has codes in 187 rate centers. Rate center names in the file are abbreviations; where one matches a Census place, the table links to that city's local-number page.
