Is my TIN the same as my SSN?

The final four digits of my SSN and TIN are the same, according to my IRS Transcript that I recently downloaded. Are they able to be the same?

Yes, TIN is the as SSN.

Yes, the last four digits of SSN and TIN can be the same. They’re often similar but used differently.

TIN is just taxpayer identification number. That is your SSN. They’re the same thing.
