- 2.4.48.1 Command Code VPPIN General Information
- 2.4.48.2 VPPIN Error Indicators
-
Voice Processing Personal Identification Number (VPPIN) is a Telephone Routing Interactive System (TRIS) command code which has three areas of functionality.
-
Generating and validating the Taxpayer Access Code (TAC), which is used in place of the Personal Identification Number (PIN) for the initial access
-
Updating, which includes creating and changing the PIN
-
Researching, which includes validating the entered PIN
-
-
First the TAC is generated and then printed on a notice or some other correspondence, which is to be sent to the taxpayer.
-
When the taxpayer uses the TRIS automated phone system, they are required to enter their TAC from their correspondence.
-
The TRIS phone system executes VPPIN, which generates the taxpayer's TAC and passes it back for verification purposes.
-
The taxpayer is then required to establish a PIN, which VPPIN stores on the Taxpayer Information File (TIF). This PIN will be used as identification for all future TRIS sessions.
-
A transaction record is sent to update the Master File.
-
For subsequent TRIS sessions, VPPIN will retrieve the PIN from the TIF and pass it back to the automated phone system for verification.
-
For security reasons special handling of the PIN has been developed. This security includes the following:
-
The PIN will be encrypted twice, once by the TRIS phone system and once by VPPIN, prior to being stored on the TIF or sent to Master File.
-
The PIN WILL NOT be displayed on any correspondence or display screen.
-
Any subsequent PIN selected by the taxpayer will supersede and overlay the initial PIN.
-
A taxpayer's account will have either a TAC or PIN, not both. Once a PIN is established, the TAC is no longer printed on any correspondence from the IRS.
