Scam Calls from Area Code 507

Area code 507 covers southern Minnesota, and the 543 complaints logged across 229 numbers between February and June 2026 paint a picture of steady, broad-based nuisance calling rather than a single dominant scheme. Complaints are still active, and the geographic footprint extends beyond the region itself, with reports filed from New York and California alongside Minnesota, suggesting callers are spoofing 507 numbers to reach targets well outside the state.

Debt-reduction pitches lead the categorized complaints at 58, followed by 68 dropped calls or silent calls that left no message — a pattern consistent with auto-dialers probing for live lines. Impersonation calls pretending to be government agencies, businesses, or family members account for 40 complaints, while lottery and sweepstakes pitches reached 15 and medical or prescription-related calls added 14 more. Specific complaint locations include Winona, Minneapolis, Rochester, Pine Island, and Waseca, spreading the activity across the 507 footprint rather than concentrating it in one city.

The top number by volume, 507-550-3861, drew 20 complaints without a clear category on record. Close behind it, 507-594-0162 generated 15 complaints and 507-460-4563 drew 12, both also uncategorized. Numbers 507-262-2666 and 507-418-3635 each produced 10 and 8 complaints respectively with no category assigned, while 507-626-2025 stands out as the one top number with a confirmed category — lotteries and sweepstakes — at 8 complaints. Two additional numbers, 507-262-2759 and 507-329-0733, round out the top tier at 8 and 7 complaints each.

Among all 358 area codes in this dataset, 507 ranks 277th overall in complaint volume, placing it in the lower third nationally. Within the Minnesota peer group of 39 area codes, however, it sits at 28th, a mid-range position that reflects genuine regional activity rather than outlier noise. FCC records tied to this code are sparse at just four, but where call type is known the split between prerecorded and live calls is nearly even — 18 prerecorded to 17 live — indicating the operation is not purely automated.

The concentration of uncategorized high-complaint numbers alongside active debt and impersonation pitches suggests a calling infrastructure still evolving its scripts, possibly testing what messaging elicits the most engagement before settling into a defined scheme. The cross-state reach into New York and California, combined with ongoing activity through at least June 2026, points to a spoofing operation using 507 as cover that has not yet run its course.
