440 area code — Willoughby, OH geographic

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

If a call shows area code 440, the number was issued in the Willoughby area — a code active since 1997, on Eastern time. The same territory is also served by its overlay code (436/440 complex). Keep in mind the code identifies where the number was registered; the person calling may be elsewhere.

The code currently holds 757 working prefixes, held by 44 different carriers. Of these, 562 are pooled prefixes shared by multiple carriers. Numbers are anchored to 62 rate centers — billing localities that fix where each prefix belongs.

The current NANPA exhaust forecast for the 436/440 complex is 2Q 2120.

The code was carved out of 216 (1997). As demand grew it in turn gave rise to 436 (2024).

Local calls inside 440 are dialed 10D; 1+10 digit dialing permissible at service providers discretion excluding cmrs providers.

To check where a specific 440 number was issued, look up its six-digit prefix; to check who is actually calling, ignore the display and verify through an official callback number — caller ID is assertable and routinely spoofed.

FAQ

Is 440 a toll-free number?

No. 440 is a geographic code; calls are billed like any other domestic call. Toll-free codes are 800, 833, 844, 855, 866, 877 and 888.

Why do 436 and 440 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 436/440 complex shares one service area, and local calls are dialed with 10 digits.

Will 440 run out of numbers?

NANPA's current forecast projects exhaust in 2Q 2120 — decades of capacity remain.

Why am I getting spam calls from 440 numbers?

Scammers spoof recognizable area codes so calls look local or familiar. A displayed 440 number does not prove the call originated there — see our guide to spotting spoofed calls.
