Once you get a copy, see if your County Clerk can record it for you. They recorded mine when I got my Marriage License.
Now when I need a copy the County Clerk can print me one out. The recording and the first 2 copys are free.
That was the first thing they told me during outprocessing from active duty in 1992. I immediately went to the courthouse, recorded my DD214 and then got six notarized copies. I put the originals in a safe deposit box.
