GG&D will provide trailer owners with a self-adhesive identification decal consisting of the characters AZ, followed by six numerals and a control number. One of our representatives certified in
Level I inspections will place the decal on the trailer, registering its VIN as a useable trailer accepted on future vehicle services. Once the AZ Number is assigned, a Special Serial Number Application,
form #48-5108, must be completed. The owner of the trailer must fill this out and make a statement as to how he/she built the trailer.
