Every area code added to the North American Numbering Plan since 2024, plus what's scheduled through 2027.
Last updated: July 11, 2026 — refreshed quarterly.
When a region's phone numbers run low, NANPA (the North American Numbering Plan Administrator) assigns a new area code. Nearly every new code today is an overlay: it shares the same geography as an existing code, and only new phone lines receive the new number. If you already have a number in the original area code, nothing about it changes.

Dates for planned (not-yet-scheduled) codes come from NANPA exhaustion projections and can shift — treat the "planned" and "reserved" rows as directional, not confirmed.
Until the early 2000s, regions running low on numbers were sometimes physically split — part of the area got a new code and had to change every printed number. That approach fell out of favor because it forced businesses to reprint materials and confused callers. Regulators shifted almost entirely to overlays, where the new code simply layers on top of the same geography. No jurisdiction in the contiguous US has approved a new geographic split since the early 2000s.
As of this page's last update, the newest area code is 465, activated Jun 18, 2026 for New York City (all five boroughs).
No. Overlays only assign new numbers to new lines. An existing number in the original area code is never reassigned.
Yes, in any overlay region — including for local calls to the same area code — you dial the area code plus the seven-digit number.
Some carrier analytics systems treat unfamiliar or newly activated area codes as a risk signal until their records catch up, typically for a few months after launch.
