Navy personnel can view and verify their online personnel records through the Official Military Personnel File (OMPF) and Electronic Service Record (ESR). The OMPF contains electronic images of career documents while the ESR contains electronic data from the Navy Standard Integrated Personnel System. Sailors should routinely review these records every 6 months to ensure accuracy and completeness, and work with their command to correct any errors. Personnel records contain sensitive personally identifiable information and must be safeguarded.
