740 area code — Newark, OH geographic

Data: NANPA public reports, current as of July 28, 2026.

If a call shows area code 740, the number was issued in the Newark area — a code active since 1997, on Eastern time. It is part of the 220/740 overlay complex — these codes share the same territory. Note that porting and VoIP mean a 740 number can be used from anywhere — the code marks where the number was assigned.

786 central-office prefixes are currently active in this code, spread across 41 code-holding carriers. Thousands-block pooling applies to 652 prefixes, so a single prefix can belong to several carriers. Its prefixes map to 187 distinct rate centers.

NANPA projects numbering capacity for the 220/740 complex to exhaust in 2Q 2059.

740 was created from 614 in 1997. It has since spawned 220 (2015).

Dialing: 10D locally, 10D to other codes (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).

Practical takeaway: the 740 label narrows geography to Ohio, the prefix narrows it to a locality, and neither authenticates a caller. Verification means calling back through a number you found yourself.

FAQ

Why do 220 and 740 cover the same place?

They are overlays: when a code runs low on numbers, a new code is added over the same territory instead of splitting it. The 220/740 complex shares one service area, and local calls are dialed with 10 digits.

Will 740 run out of numbers?

NANPA's current forecast projects exhaust in 2Q 2059 — decades of capacity remain.

Why am I getting spam calls from 740 numbers?

Scammers spoof recognizable area codes so calls look local or familiar. A displayed 740 number does not prove the call originated there — see our guide to spotting spoofed calls.

Where is a 740 number from?

740 is assigned to Newark and surrounding areas of Ohio in the Eastern time zone. The three digits after the area code (the prefix) narrow it down to a rate center.

Is 740 a toll-free number?

No. 740 is a geographic code; calls are billed like any other domestic call. Toll-free codes are 800, 833, 844, 855, 866, 877 and 888.
