Depending on the make and model of your safe, there are several locations to possibly look (it is on the outside of the safe somewhere.
Try the right hand side (outside) of your door, between the hinges OR on the under edge of the front lock plate OR on the back of the unit OR behind the handle. Usually it is on a small plate on the outside somewhere.
If you area still unable to locate, contact me back.
