When the Chief signs them,or you get the call or when you pick them up? Only asking because I may not be around for a while when the call comes, could be up to 3 weeks.

For my dept, it is when the Chief signs them as that is the last step. He dates it, then hands it over to the secretary to call and tell you they're ready.

I believe that is true. The date they are issued is normally the date they are signed by the Chief.

Come to think of it, my PD sent a letter when it was in. They never called. The permit was dated the same as the letter.
