Colorado Will Join State-to-State Verification Service

DENVER Tuesday, Jan. 7, 2020 -- On Monday, Jan. 27, 2020, Colorado is expected to implement the American Association of Motor Vehicle Administrators (AAMVA) State-to-State (S2S) information sharing program, joining 26 other participating states. By joining the program, Colorado's Division of Motor Vehicles (DMV) is helping to protect our customers against identity theft and ensuring Coloradans only have one REAL ID-compliant driver license or ID card.

S2S provides a means for states to electronically check with all other participating states to determine if the applicant currently holds a driver license or identification card in another state. State participation in the program is voluntary. Unexpired, out-of-state credentials, which are often no longer in use, could be used for identity theft if they fell into the wrong hands. Two separate credentials also means two separate records, which can make it more difficult to identify or act upon serious driving violations.

With this implementation, those with credentials in more than one participating state will retain only the most recently-issued credential.

In implementing the S2S program, the DMV is proactively protecting Coloradans and the identities of those who transferred or are transferring credentials to another state. Prior to S2S, Colorado and other states relied on an applicant's self-attestation when signing a license or ID card application, with no ability to verify information beyond what a person offered voluntarily.

The information exchanged between participating states in the S2S program is only enough to point inquiring states to the jurisdiction with the applicant's record. This information includes name, birthdate, customer identification number and the last five digits of an applicant's Social Security number. The federal government does not have access to the S2S service and the law that funded the development of S2S prohibits the creation of a new means of access for federal agencies.
