Scam Calls from Area Code 650

Impersonation calls are the defining threat in area code 650, accounting for 500 of the 1,755 total complaints logged against this San Francisco Peninsula code between February and June 2026. A single number, 650-203-0000, is responsible for 245 of those 500 complaints on its own, making it by far the most-reported number in the entire dataset. Two additional numbers, 650-215-5272 with 22 complaints, contribute to the same impersonation category. The calls are prerecorded in the majority of cases, with 611 prerecorded contacts recorded against 260 live calls, a delivery pattern consistent with high-volume spoofed-identity campaigns rather than targeted personal fraud.

Debt-reduction solicitations form the clear second tier of activity, drawing 235 complaints across the code. Three numbers drive this category: 650-253-0000 at 25 complaints, 650-431-3824 at 20, and 650-881-2073 at 13. Collectively these numbers concentrate the debt-reduction pitch into a tight cluster of 650-prefix lines, and the use of prerecorded delivery across the broader code suggests these campaigns share infrastructure with the impersonation operation or at least operate in the same coordinated environment.

Two numbers, 650-265-6786 with 32 complaints and 650-204-1111 with 26, account for a combined 58 complaints without falling into any named category. That places 650-265-6786 as the second-most-complained-about number in the entire code, behind only 650-203-0000, which gives it notable weight despite the absence of a category label.

Reported locations tied to 650 activity span San Carlos, San Francisco, San Jose, Van Nuys, and Moorpark in California, with additional complaints originating from Ohio and Florida, indicating that the spoofed 650 prefix is reaching well beyond the Bay Area. The code ranks 10th out of 43 California area codes by complaint volume, a standing that reflects meaningful regional concentration. With impersonation activity still recorded as ongoing through June 2026 and 650-203-0000 alone generating nearly one in seven complaints across the entire code, the impersonation cluster remains the primary threat vector and shows no sign of contraction.
