SECTION 6--DATE OF BIRTH (DOB) AND PROTECTED PERSON DATE OF BIRTH (PPB)
FIELDS
The DOB is expressed as a Gregorian date (YYYYMMDD): year (YYYY), month (MM), and day (DD). All records
should be entered with a complete DOB, if available. When the complete date is not available, zeros can be used for
an unknown month or day. If a DOB is the only searchable numeric identifier, it must be complete, including year,
month, and day. PPN information must be entered as a complete, valid Gregorian date. Records entered into the
Sexual Offender Registry File, records for Wanted and Missing Person File juveniles, and Missing Person File records
containing MNP/CA must contain complete, valid Gregorian DOB information. In inquiries of the person files, if DOB
is used, it must be a complete, valid Gregorian date. For example:
