Are TIN numbers for Social Security benefits standard or unique to each person?

[ColeenD3]

ITINs are unique like social security numbers are.

BUT...if you are entering an SSA-1099?....and the TTX form you are putting it into is asking for a TIN???

THEN you are entering that SSA-1099 into the wrong software form !   Get out of that form and delete it.

Then find the proper SSA-1099 area in the Retirement income section and enter it there..

Where do I enter an SSA-1099, SSA-1099-SM, or SSA-1099-R-OP1? (intuit.com)
