Scam Calls from Area Code 909

Area code 909, anchored in the Inland Empire cities of Fontana, San Bernardino, and Walnut, California, has generated 2,094 complaints across 898 distinct numbers since February 2026, with activity still ongoing as of June 2026. That volume places it 57th out of 358 area codes overall, but 6th out of 50 among its California peer codes — a regional concentration that marks 909 as a notably active source within the state.

The single largest complaint category is dropped calls or no message, with 413 complaints, suggesting a substantial robocall or auto-dialer operation that frequently fails to connect or deliver a payload. Impersonation calls — those pretending to be government agencies, businesses, or family members — account for 240 complaints, the second-highest category. Debt-reduction pitches covering credit cards, mortgages, and student loans add another 157 complaints, and home improvement and cleaning solicitations contribute 111 more. Medical and prescription-related calls round out the tracked categories at 45 complaints.

The top number by a wide margin is 909-377-4238, which has drawn 68 complaints with no categorized subject on record. The second-ranked number, 909-378-4263, carries 20 complaints under the same condition. Together these two numbers account for a disproportionate share of volume among the top eight. Numbers 909-791-1976, 909-869-8533, and 909-869-6983 each appear in the dropped-call category, while 909-901-5682 is specifically tied to impersonation complaints with 10 reports.

FCC records show 51 live-agent calls versus 17 prerecorded contacts, a ratio that distinguishes 909 from area codes dominated by automated robocall blasts. Live-agent activity at this scale — spread across impersonation, debt reduction, and home services categories — points to organized call-center operations rather than opportunistic one-off dialing. Complaints have also been reported from Nevada and Florida, meaning numbers assigned to Inland Empire exchanges are reaching well outside their home geography.

The threat profile here is one of sustained, multi-category pressure driven by a relatively large pool of active numbers, with a small cluster of high-volume lines doing concentrated damage. The presence of live agents across impersonation and debt-relief categories, combined with the uncategorized dominance of 909-377-4238, suggests coordinated operations that have not yet been fully characterized — and that show no sign of tapering.
