3. AAMVA card masking, when enabled, works as follows:
a. Tracks 1 & 3 are sent entirely masked i.e., zeros are supplied in all character
positions.
b. Track 2:
• The goal is to send the Driver License ID (DLID) partially masked, the
Expiration Date in the clear, the Birth Date in the clear, and the rest of the
track masked.
• If the DLID, Expiration Date, or Birth Date are not correctly structured, the
rest of the track (from the point of discrepancy) will be sent in the clear.
• If the DLID, Expiration Date, or Birth Date contain the ‘?’ character (End
Sentinel), the field is not correctly structured.
• A correctly structured DLID has a maximum of 19 digits and is ended by the
character ‘=’ (Field Separator).
• A correctly structured Expiration Date has 4 characters.
• A correctly structured Birth Date has 8 characters.
