Scam Calls from Area Code 563

Area code 563 covers eastern Iowa, anchored by Dubuque and Davenport, and has generated 302 complaints across 131 numbers since February 2026, with activity still ongoing as of June 2026. Among Iowa-assigned codes it ranks 34th out of 39 tracked, placing it toward the lower end of in-state volume, though the complaint-per-number ratio and the persistence of activity over five months make it worth watching.

Debt-reduction solicitations are by far the dominant complaint category, accounting for 69 of the 302 total complaints and covering credit cards, mortgages, and student loans. That tally is more than twice the next largest category, dropped calls or no message, which drew 47 complaints. Impersonation calls — targeting people across Iowa, California, and Florida — added 18 complaints, while medical and prescription pitches contributed 17 and warranty or protection-plan calls added 6.

The dropped-call category is notable for concentrating its volume in a small number of numbers. 563-800-7579 and 563-306-2667 are the two highest-complaint numbers in the entire code, at 13 and 11 complaints respectively, both flagged specifically for dropped calls or silent connections. 563-551-8238 adds another 5 complaints in the same category. That pattern — three numbers, 19 combined complaints, all producing no audible content — is consistent with auto-dialer probing or number validation sweeps rather than live solicitation.

Four other numbers, 563-244-0102 (7 complaints), 563-766-3375 (6), 563-204-4487 (5), 563-202-8237 (5), and 563-766-3241 (5), round out the top tier with a combined 28 complaints but no assigned category in the complaint data. The lone FCC record for the code logs a prerecorded call, aligning with the robocall mechanics suggested by the dropped-call cluster and the debt-pitch volume.

The reported origination points extend beyond Iowa itself — Argyle, Texas and LaGrange, Illinois appear alongside Dubuque, Davenport, and Council Bluffs — indicating that 563 numbers are being spoofed or registered by operations with no genuine geographic tie to eastern Iowa. With debt-reduction fraud as the clear lead threat, a silent-dialer sweep apparently running in parallel, and out-of-state actors using the code as cover, 563 presents as an active spoofing surface being worked on multiple fronts simultaneously.
