Form 1040-V

[buelfarm]

Does anyone know what the numbers are that print across the bottom of Form 1040-V when a client has a balance due?  Someone asked me & I can see the primary SS #, then 2 Alpha characters ??, then the first 4 letters of the primary last name, followed by a series of numbers.  This client is upset to think that the 2 Alpha characters do not match either of their names ... Clearly, it's something in the software, but I don't know what to tell them ...

" This client is upset to think that the 2 Alpha characters do not match either of their names"

Tell them that DOGE has updated databases and the alpha characters don't match because DOGE believes they were adopted at birth.

Sounds like your clients need to find a hobby if they are that worried about what letters show up on a payment voucher.

It's a "check digit," although it's really an alpha code for the SSN, to make sure that the SSN is entered correctly.  This is from the Internal Revenue Manual, although it refers to a different form where the letters are to the left, not the right:

3.24.10.2.5 (01-01-2017)
