Business Account Numbers

A Business Accounts Number (BAN) is a 7-digit number assigned to registered businesses by the San Francisco Treasurer & Tax Collector’s Office. A registered business will have a single active BAN for all open business locations. SmallBusinessCentral uses Business Accounts Numbers (BANs) as unique identifiers for small businesses. You can find the BAN for a registered business on the list of registered business lookup tool published on DataSF.
