Scam Calls from Area Code 720

Area code 720, Colorado's overlay for the Denver metro and surrounding communities, has generated 2,463 complaints across 986 distinct numbers since February 2026, with activity still ongoing as of June 2026. That volume places it 37th out of 358 area codes tracked overall, and 4th among the 47 Colorado-region codes — a concentration that makes it one of the heavier-complaint corridors in the state. Reported locations span Denver, Aurora, Littleton, Colorado Springs, and Pine, though complaints have also been filed by recipients in New York and California, indicating the numbers are being routed well outside their registered geography.

The single largest complaint category is dropped calls or no message, with 422 complaints — a pattern consistent with autodialer probing, where calls are placed faster than agents can answer and then abandoned. The top individual number in the code, 720-789-3005, accounts for 42 complaints in this category alone. A second number, 720-456-3746, adds another 11 dropped-call complaints, suggesting at least two active dialing campaigns operating on this model.

Impersonation calls are the second-largest category at 307 complaints, with 720-738-7264 as the standout number at 34 complaints. Debt-reduction pitches follow at 251 complaints; 720-891-5261 and 720-704-5971 have drawn 18 and 15 complaints respectively in this category, targeting credit card, mortgage, and student loan holders. Home improvement and cleaning solicitations account for 66 more complaints, and medical and prescription calls add 49.

Four numbers — 720-995-6443 and 720-202-392-2027 and 720-456-3775, carrying 15, 13, and 12 complaints respectively, along with 720-456-3746's 11 — appear without a mapped category but together represent a meaningful slice of uncharacterized volume that cannot be attributed to the known campaign types above.

The threat read here is a code operating across several simultaneous scam tracks rather than a single dominant scheme. The combination of high-volume abandoned-call probing, active impersonation dialing, and a parallel debt-solicitation push across multiple numbers suggests coordinated or at minimum parallel operations using 720 numbers as cover. With activity still live and the code ranking fourth among Colorado overlays, pressure on this prefix shows no sign of tapering.
