563 is the area code for Davenport, Iowa, in service since March 25, 2001, Central time. 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 387 active NXX prefixes in 563, assigned to 73 carriers. 276 of those prefixes are pooled — shared between carriers in thousands-number blocks. The code spans 109 rate centers (billing localities).

To check where a specific 563 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.

The dialing plan is 7D for home-NPA local calls and 10D across codes.

Official projections put exhaust at 4Q 2076.

Its parent code is 319, which it left in 2001.

FAQ

Why am I getting spam calls from 563 numbers?

Scammers spoof recognizable area codes so calls look local or familiar. A displayed 563 number does not prove the call originated there — see our guide to spotting spoofed calls.

Where is a 563 number from?

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

Is 563 a toll-free number?

No. 563 is a geographic code; calls are billed like any other domestic call. Toll-free codes are 800, 833, 844, 855, 866, 877 and 888.

Will 563 run out of numbers?

NANPA's current forecast projects exhaust in 4Q 2076 — decades of capacity remain.
