Area code 563

Area code 563 serves Iowa, including Davenport, Dubuque and Muscatine (Central time). It has been in service since March 25, 2001.

Numbers starting with 563 drew 855 reports to the FTC from Aug 14, 2026 to Nov 11, 2026 and 220 complaints to the FCC since November 2023. The number on your screen can be faked, so a 563 number proves nothing about where a call came from.

Phone companies holding 563 exchanges

Each exchange (the three digits after the area code) is assigned to one carrier. 71% of these exchanges are pooled: their numbers are handed out in blocks of 1,000 to other carriers, so the holder below is not always the company serving a given number.
