AAMVA's mDL Digital Trust Service (DTS) provides relying parties with the single best source to confirm the veracity of an mDL. AAMVA's DTS provides trust to relying parties by ensuring only true issuing authority keys are added to the DTS, issuing authority mDL programs adhere to the ISO/IEC 18013-5 standard and AAMVA's Mobile Driver’s License Implementation Guidelines, Version 1.2, and industry best practices for key management are followed.

AAMVA uses secure methods of obtaining and updating the public keys to minimize the risk that invalid keys may be presented to the system. Once obtained, the DTS publishes the public keys to the DTS Verified Issuer Credentialing Authority List (VICAL). As AAMVA adds issuing authorities' public keys to the DTS, the VICAL is continuously updated, minimizing the level of effort required for relying parties to keep track of and update their readers to consumer compliant mDLs.

Below is a graphic that visually describes the flow of keys between the issuing authority, the DTS, and relying parties.

All relying parties can download the VICAL and load it in their mDL reader technologies. The download must take place prior to engaging with an mDL. Relying parties can gain free access the VICAL by clicking on the button below.
