Area code 609 is a geographic code serving Atlantic City, New Jersey in the Eastern time zone. It has been in service since January 1, 1957. Together with 640 it forms the 609/640 overlay. Because of number portability and VoIP, the area code tells you where the number was issued, not where the caller is right now.
NANPA lists 779 active NXX prefixes in 609, assigned to 40 carriers. 528 of those prefixes are pooled — shared between carriers in thousands-number blocks. The code spans 50 rate centers (billing localities).
Its parent code is 201, which it left in 1957. Later relief produced 856 (1999), 640 (2018) from its territory.
Official projections put exhaust for the 609/640 complex at 3Q 2046.
The dialing plan is 10D for home-NPA local calls and 1+10D across codes.
Worth noting: 609 is covers more rate centers (50) than any other New Jersey area code.
Practical takeaway: the 609 label narrows geography to New Jersey, the prefix narrows it to a locality, and neither authenticates a caller. Verification means calling back through a number you found yourself.

FAQ
Will 609 run out of numbers?
NANPA's current forecast projects exhaust in 3Q 2046 — decades of capacity remain.
Why am I getting spam calls from 609 numbers?
Scammers spoof recognizable area codes so calls look local or familiar. A displayed 609 number does not prove the call originated there — see our guide to spotting spoofed calls.
Where is a 609 number from?
609 is assigned to Atlantic City and surrounding areas of New Jersey in the Eastern time zone. The three digits after the area code (the prefix) narrow it down to a rate center.
Is 609 a toll-free number?
No. 609 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 640 and 609 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 609/640 complex shares one service area, and local calls are dialed with 10 digits.
