State-to-State (S2S) Verification Service

The State-to-State (S2S) Verification Service is a means for a state to electronically check with all other participating states to determine if the applicant currently holds a driver license or identification card in another state. The platform that supports S2S, the State Pointer Exchange Services (SPEXS) was successfully implemented in July 2015. Participation in S2S does not commit a state to be in compliance with the federal REAL ID Act. However, if a state chooses to be REAL ID compliant, the Department of Homeland Security generally looks for S2S to be part of their compliance plan.

S2S satisfies these key business requirements:

  • S2S limits a person to one driver license (DL)
  • S2S enables a state to determine whether a person holds a DL or identification (ID) card in another state
  • S2S enables a state to send a request to another state to surrender or invalidate a DL/ID
  • For states that comply with REAL ID, S2S limits a person to one REAL ID credential (either a DL or an ID) by enabling a state to determine whether a person holds a REAL ID credential in another state

For additional information on S2S, please see our frequently asked questions. To understand how AAMVA and participating jurisdictions protect the privacy of the information in S2S, see the State Pointer Exchange Services (SPEXS) Privacy Impact Assessment (available to jurisdiction and federal members).

Driver History Record

S2S now also offers an additional feature, the Driver History Record (DHR) functionality, which supports the concept of one driver, one history record. This is the ability to transmit out-of-state convictions and withdrawals between states for noncommercial drivers. The DHR supports this real-time exchange of information by providing visibility of individuals who may have more than one driver history record and sets rules for maintaining driver history records in a standardized manner. Not only does this lead to a decrease in processing time but it also leads to an increase in driver history accuracy and completeness, which ultimately makes roads safer for all drivers.

Grant Funding for S2S

The National Highway Traffic Safety Administration (NHTSA) and the Department of Homeland Security (DHS) have annual grant programs that are available for states that wish to offset costs associated with the implementation and operation of the S2S service.

Reports


State Pointer Exchange Services (SPEXS) Web UI Reporting Portal

The SPEXS WebUI Reporting Portal is an AAMVA web application that allows authorized jurisdictional users to access SPEXS reports. These reports help jurisdictions monitor data quality and timeliness of various aspects of their operations, including convictions and withdrawals posting timeliness. These reports help jurisdictions monitor data quality and timeliness of various aspects of their operations, including convictions and withdrawals posting timeliness. See here for more information about S2S reports.

S2S participates in the CD31 run. To view the CD31 status of jurisdictions, see here (available to jurisdiction and federal members only).

SPEXS Duplicate Resolution Tool

This is a user interface that is available for S2S states and enables states to collaborate with other states and share information about specific potential duplicate pairs. The interface allows states to exchange notes and other information via a common platform. View the Duplicate Resolution Tool User Guide to learn more. Visit here to see the jurisdictions who participate in the SPEXS Duplicate Resolution Tool (available for jurisdiction and federal members).

Using the SPEXS Duplicate Resolution Tool, you can:

  • View list of unresolved duplicates
  • Search for a particular duplicate record
  • Share and gather more information on potential duplicates
  • Exchange data
  • Exchange images/attachments
  • Mark records to alert other states about possible fraudulent activity on records
  • View additional duplicates for duplicate pointers
