No employers state id number on w2

Do you have entries in box  16 and 17 of the W-2

I have entries in both blocks: 16 and 17 but no EID in 15

What state?

My state is Alabama.  Same employer provided the EID for the state last year.

I have answered your question below.

You can enter the number you entered for the Federal EIN or 999999999 for the State ID number. 

Does this go for New York State.  The City of NY did not provide a State ID #.

Thank you for your answer. It is very helpful. I couldn't get this answer from the turbotax online support help.
