Scam Calls from Area Code 951

Area code 951, anchored in the Inland Empire cities of Riverside, Temecula, and Jurupa Valley, has generated 1,865 complaints across 727 distinct numbers since February 2026, with activity still ongoing as of June 2026. Among the 50 California area codes tracked, it ranks 10th by complaint volume, a position that places it firmly in the upper tier of the state's most-reported prefixes.

Impersonation calls lead the named categories at 274 complaints, with 951-517-2071 alone drawing 31 of them and 951-944-0443 adding another 16. Debt-reduction solicitations follow at 167 complaints; 951-477-3992 accounts for 27 of those and 951-524-5639 contributes 13 more. The home-improvement and cleaning category reaches 114 complaints, with 951-305-9271 responsible for 12. Medical and prescription calls appear through 951-234-0989, which has accumulated 15 complaints on its own.

The 288 dropped-call or no-message complaints are the single largest category in the dataset, suggesting a substantial robocall or auto-dialer infrastructure behind the operation. FCC mode data reinforces this: of the 9 FCC records tied to the code, the breakdown skews heavily toward live calls at a 69-unit weight, but prerecorded contacts register at 21 and text messages at 15, pointing to a multi-channel delivery setup rather than a single method.

Two numbers, 951-277-6311 with 18 complaints and 951-377-3896 with 11, carry no category assignment but between them represent nearly 30 additional complaint events. Complaints have also surfaced from receivers in Texas and Florida, meaning the calling activity is not contained to the Riverside-area geography the prefix nominally covers.

The combination of active impersonation lines, a high dropped-call volume consistent with number-cycling, cross-state reach, and persistent activity across five months points to an organized operation using 951 numbers as rotating cover rather than a cluster of isolated bad actors.
