SoFi Money currently accepts signed personal checks, paystub checks, and cashier's checks. We also accept Money Orders - please make sure the Money order has "for electronic deposit at SoFi only" on the back.
We do not currently accept credit card checks, 3rd party checks, certified checks, or remotely created checks (i.e. Demand Drafts). We're always evaluating enhancements and will continue to work on accepting additional check types.
