Pennsylvania Certification of Service is a document issued by the Pennsylvania Department of State that verifies the identity of an individual who has served in the U.S. Armed Forces, the reserves, or the National Guard. It is used to demonstrate a veteran’s service and eligibility for veteran benefits. There are two types of Pennsylvania Certification of Service: Pennsylvania Form DD-214 and Pennsylvania Form DD-256. The DD-214 is a record of a veteran’s service, showing the dates served, awards received, and other pertinent information. The DD-256 is a certificate of honorable discharge. Both forms are issued by the Pennsylvania Department of State and must be signed by the veteran.
