SAP (Systems Applications and Products) is a California-based provider of enterprise-level business process software. Many local governments have adapted SAP software for their various administrative functions. An SAP number is a unique six digit number used by a municipality to identify a vendor in its system. Municipalities that use SAP generally require all registered vendors have a SAP number.
