Is it ok to have your social security number but not card?

the good news is I recently got hired for a job and will start work on Wednesday. The bad news is they want me to show my Driver's License and Social Security card when I come in on Wednesday. I have my license and plenty of documents with my Social Security number on it, but not a card. Do you think they'd give me a hard time or as long as I have something with my SS # on it it should be ok?
