It's possible. Whether you'll be accepted for employment or not with such an RE code depends on the company you're trying to work for. If it requires any sort of security clearance, it'll probably be a strike against you.
Just ask to see a persons military id card, if they are currently serving. If they are prior service (out of the military) then ask to see their DD214. (discharge papers) The DD214 is the only real proof of military service.

If you want to re-enlist in the military, take your DD214's to a recruiter and have them file an appeal with the Department of Defense about your discharge. The recruiter will let you know what the DoD is requiring you to do to get back in the service. The other thing to do would be file an appeal with the Department of Defense on your discharge. There is no way to change your enlistment code on your DD214's because that would be considered fraud.
According to the website United States Department of Veterans Affairs, DD214 has been issued by military services since January 1, 1950. Before January 1, 1950, several similar forms were used by the military services. DD256A is listed as Honorable Discharge Certificate. However, a Form DD256A may have been issued after 1950 if that form was still in possession of the signer, who hadn't switched over to DD214.
Ask to see his DD214. No DD214, he didn't serve. If info's not on his DD214, it didn't happen.
The service number is located on the first line of the DD-214, in a block titled: :Service Number"
