Arizona became the seventh U.S. state to join the AAMVA Digital Trust Service (DTS). With the increasing number of jurisdictions now issuing or working toward implementing ISO/IEC 18013-5 compliant driver licenses, the need for a single, safe, and secure point of trust for mDL public keys is growing. Arizona's inclusion in the DTS represents a great step forward in supporting adoption and acceptance of interoperable and privacy-respecting digital credentials in North America.
