Welcome to Fluther. You really need to give us a little bit of detail on the question. I’m presuming that you mean “Temporary Driver’s License” and “Department of Public Safety”, but there’s no clue about where this is, and the term “audit number” is unfamiliar to me. Have you checked the DPS website for your particular jurisdiction? Usually this is the kind of frequently-asked question that gets answered fairly clearly and in a spot where you’re likely to see or find it… so that they don’t have to answer this obvious question all the time. On a somewhat related note: It’s a good idea to preserve copies (scanned or paper, whichever works for you) of your important documents in a secure location so that you can refer to them when they are unavailable to you… such as in cases like this.
