Gepasporteerd (literally: passported) means a passport was issued. You will typically come across the term in military service records in the 1800s. At the end of service, a soldier received a passport to show he fulfilled his military duties. Since these passports were given to the soldiers, they may have survived in private collections but are unlikely to turn up in archives.
See the reader question about military passports in the 1800s for an example.
