2.3.68. Command Codes DUPOL and DUPPG

(1) Overview: CFOL command code (CC) DUPOL is designed to research and display information to assist in fraud detection of SSNs in both paper and electronically filed returns. CC DUPOL extracts taxpayer information from the Duplicate TIN database that contains tax return information for the Tax Processing years 2022, 2023 and 2024. Command Code DUPPG is a subsidiary command code, and provides a second page–when available—of Duplicate TIN data once DUPOL has been used for the first page.
