I dont see a document number on my drivers license only an id

[AnthonyC · Accepted solution]

This tends to come up with New York driver's licenses, so I am going answer assuming you are in New York.  The document number is an 8 or 10 digit alphanumeric number found either on the back of the license or lower right hand corner (depending on the year of your license).   It is not the same as the drivers license number.  I have included a link to the NY authority that displays images below.

If someone is an out-of-state (e.g., an NJ resident) filing an NY non-resident return, what does one use to fill in the 3-character document number?

As long as you are inputting a valid state ID from any state there should be no processing issues for NY.

For NJ driver's license, would the document# be the DL# or something else?

If your driver's license in New York was issued about 2012 or 2013 (like mine) you will need a magnifying glass, or zoom in all the way with your camera and take a pic of it because it looks like a red line in the lower right-hand corner, but is actually a tiny set of letters and numbers.  I think some are on the front lower right corner or maybe on the back lower right corner.
