FAQ

Why do 903 and 430 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 430/903 complex shares one service area, and local calls are dialed with 10 digits.

Will 430 run out of numbers?

NANPA's current forecast projects exhaust in 1Q 2047 — decades of capacity remain.

Why am I getting spam calls from 430 numbers?

Scammers spoof recognizable area codes so calls look local or familiar. A displayed 430 number does not prove the call originated there — see our guide to spotting spoofed calls.

Where is a 430 number from?

430 is assigned to Longview and surrounding areas of Texas in the Central time zone. The three digits after the area code (the prefix) narrow it down to a rate center.

Is 430 a toll-free number?

No. 430 is a geographic code; calls are billed like any other domestic call. Toll-free codes are 800, 833, 844, 855, 866, 877 and 888.
