To determine if a vendor is registered in MAIN, enter the vendor’s tax identification number on screen 5220.  Remember to put a “2” in front of a company identification number and a “3” in front of an employee social security number.

If you do not have the federal tax identification number, you can look up the vendor by name using the ADPICS screen 1200 - Vendor Name Inquiry (F10 on screen 5001 - Vendor Maintenance/Inquiry Menu).  The vendor name that is in the vendor file will be the name provided by the vendor on their W-9 form.

Please note that existing mail codes will be changed only to correct data entry errors or to update the phone number, fax number, contact person, or mail type flags.  All other types of changes will require a new mail code, with the exception of the 000 mail code (the mailing address for 1099 reporting). The 000 mail code is never changed.  Also, individual names should not be used on the attention lines.  We suggest that position titles be used instead.
