Program Scope and Objectives

  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.

  2. Purpose: These sections provide instructions for accessing Duplicate TIN information through the Duplicate TIN (DUPTIN) database files in Martinsburg, WV.

  3. Audience: IRS Tax Technicians, Account Management employees, and Criminal Investigator

  4. Policy Owner: Director, Corporate Data Domain(CP)

  5. Program Owner:Tax Data On-line (TDOL), a branch within CP

  6. Primary Stakeholders: Criminal Investigation (CI), Wage and Investment (W&I), and any other IRS organization profiled with IDRS access.

  7. Program Goals: As an aid to the detection of fraudulently-used Taxpayer ID numbers, these are the instructions for using the CFOL/IDRS command code DUPOL and its subsidiary paging-utility command code DUPPG. Details below.

Command Code DUPOL Output Screens

  1. Some of the features of the DUPOL command code output display screens include:

    1. CC DUPOL will display Nationwide and individual Service Center counts of how many times a particular SSN was used for the desired year. These counts will only be displayed on the first screen if multiple pages exist.

    2. CC DUPOL will display how many times the SSN was used, how it was used, and who used it.

    3. CC DUPOL will provide IDRS-like paging when multiple records exist.

    4. The paging routine will automatically position the cursor following the Start of Message symbol. When the ENTER key is depressed, the terminal will display the next page or any page designated by overlaying a page number onto the format by key input.

    Caution:

    Do not leave the terminal in a paging condition. Since no entry code is needed for input, anyone could depress the ENTER key and have unauthorized access to the display. Terminate terminal session by inputting SINOF.

If further investigation cites a DB2 systems error, problem will be escalated to appropriate IBM Database Support Section by the production DBA as mandated by existing Service Level Agreements.

    11. A PAGING REQUEST WAS ENTERED BEFORE A DUPOL REQUEST WAS ENTERED - an attempt to retrieve an additional page was performed before an initial DUPOL request was made.

    12. NO SCREENS AVAILABLE - The attempt to retrieve an additional screen was unsuccessful, no additional screen exists.

    13. INVALID TRANSACTION REQUEST - The CC request was invalid due to a missing or invalid definer code.
