I-765, Question 9

I received my documents 2 years ago with out any problems. I need to renew now and while filing out the form i noticed that question 9 on the work permit application says in quoits to include any and all ss # used. I did use a fake ss # for about 2 years prior to getting DACA. I dont remember if i included that number when i first applied for DACA. How big a problem is this? If i put it in now that i am renewing is this a big issue? I do have copies of the things i sent in but i dont see that i wrote down that number. I didn't use a lawyer because i have no past criminal record or anything. I dont even have traffic stops and while everything turned out fine i dont know what to put down in that slot. Any advice would be greatly appreciated.

Just put the new SS# i think nobody put the fake SS# for the initial application

Oh I think alot of people did. Some sent their payments and such that had their fake ssn
