Yes, all 0's do not work. I used my own EIN. Also, you can find tons of EINs by doing a general web search. I'd rather be able to leave blank, just so I remember to correct the data later. However, I do meticulously check each entry when an actual report such as a 1099 is received, so it's not likely I'd submit the nonsense I put in as a placeholder. Interesting that the Census has info about getting their EIN , but doesn't actually provide it.
