Scam Calls from Area Code 623

Area code 623 covers the western Phoenix metro, concentrated in communities including Surprise, Glendale, Peoria, and Sun City. The code has generated 971 complaints across 402 numbers since February 2026, with activity still ongoing as of June 2026. At rank 204 out of 358 area codes tracked, volume is moderate overall, but among Arizona area codes specifically it sits at 22nd out of 43, placing it in the busier half of the state's footprint. Complaints have also been filed by callers reached in Florida and Texas, indicating the numbers are not limiting their targeting to the local region.

The single largest complaint category is dropped calls or no message, with 163 complaints — a pattern consistent with robocall probing, where autodialers test lines before connecting live agents. Several of the most-complained numbers fall squarely into this bucket: 623-352-9401 drew 16 complaints, 623-462-7104 drew 14, 623-352-9402 and 623-352-9406 each drew 13, and 623-462-7106 drew 12. The sequential structure of numbers like 623-352-9401, -9402, and -9406 strongly suggests they originate from a single dialing operation cycling through a number block.

Impersonation calls rank second with 98 complaints, and the top individual number in the dataset, 623-228-9898, accounts for 20 of those complaints alone. The debt-reduction category follows with 51 complaints, targeting credit cards, mortgages, and student loans, while medical and prescription solicitations account for 48 complaints — a figure notable given the Sun City and Peoria presence in the reported locations, both of which skew toward older residents. Number 623-228-4101 drew 12 complaints in the medical and prescriptions category. Vacation and timeshare pitches add another 17 complaints.

The mix of live calls (78 FCC-mode complaints), text messages (47), and prerecorded calls (10) points to a multi-channel operation rather than a single automated campaign. The clustering of dropped-call numbers in apparent sequential blocks, combined with an active impersonation line generating the highest individual complaint count, suggests at least two distinct operations using 623 numbers simultaneously. The ongoing recency status and the spread of complaints into Florida and Texas indicate neither campaign has wound down, and the debt and medical categories leave the area code's retirement-age communities particularly exposed to sustained pressure.
