A vendor code is a unique identifier assigned to a vendor, producer, or insurance company that receives checks from an agency. It is a transaction code assigned by one party to another for convenience of transactions between the parties. Vendor codes provide the ability to track and pay premiums and to track vendors for vendor reconciliation and escrow payments. Vendor codes are used in various contexts, such as accounting, procurement, and compliance. For example, in SAP MM, a vendor code is the vendor number used to create a purchase order. In Amazon Vendor Central, a vendor ID is a unique code that reflects the group the user is associated with in Vendor Central. Vendor codes can be maintained in a vendor master file, which stores information on any business or individual, other than a client, who receives checks from an agency. The vendor file also includes entries that indicate whether the system should print check stubs for vendors or whether vendors require 1099 forms at year-end.
