VRS 101: Interoperable Databases & Web Services Glossary

VRS 101: Interoperable Databases & Web Services Glossary

One of the advantages to voter registration systems utilizing a modern platform is the ability to integrate with external databases. Automated interoperability allows for seamless data transfers, which reduces the manual tasks that are typically required to interact with external interfaces. Human error is reduced, and the end result is simplification, increased efficiency, and increased accuracy in voter management.

Here is a list of databases that can integrate with voter registration systems and the information supplied by each. (Please note, availability varies by State)

Does your jurisdiction use a database not on the this list? Please email us and let us know about it!


Department of Corrections (DOC)

What is it?
Database lists the date of incarceration and date of release for convicted felons.

Integration Benefit
Deactivating incarcerated voters from rolls prevents anyone from voting in their name. Date of release is provided so voting status may be reinstated, if allowed by the State.



Electronic Registration Information Center (ERIC)

What is it?
A voluntary partnership between states to improve the accuracy and efficiency of voter registration systems, certain states share voter data including name, address, date of birth, and last four of social security number.

Integration Benefit
A secure data-matching tool looks for duplicate voters, voters who have died, or voters who have moved within or out of state in an attempt to clean voter rolls so they are as accurate as possible.


Melissa Global Intelligence (Melissa)

What is it?
Melissa provides identity verification and USPS verified addresses with geocoding.

Integration Benefit
Melissa data connects to voter registration systems and verifies addresses in real time. A query will return look ahead suggestions to complete address fields, and also standardizes addresses and breaks them down into their individual components. This helps ensure addresses are valid and formatted properly for the VRS. Melissa provides geocoding by mapping addresses to a precise latitude and longitude.


Department of Motor Vehicles/Motor Vehicle Division (DMV/MVD)

What is it?
A state’s motor vehicle division contains voter information such as addresses, signature, driver's license and social security numbers. People are more likely to update their address here than to remember to independently update their voter registration information with the county clerk.

Integration Benefit
Using web services, the VRS can interface with DMV/MVD data to identify changes to voter records, and access required voter data and signatures. The driver’s license number and social security number data also provided by the DMV/MVD is another step in ensuring accuracy of people on the voter rolls.


National Change of Address (NCOA)

What is it?
Established by USPS, the database contains change-of-address records for people who have moved and filed their new address to have mail forwarded.

Integration Benefit
With approximately 160 million permanent change-of-address records, the NCOA is a good source for current addresses. Much like the motor vehicle division, people are more likely to remember to forward their mail than to change address with election division. 


National Death Index (NDI)

What is it?
A Centralized database of death record information established by the National Center for Health Statistics.

Integration Benefit
Records are matched by satisfying at least one of seven conditions or matching criteria.


Social Security Administration (SSA)

What is it?
The SSA provides a master file of deaths.

Integration Benefit
Deceased voters can be properly marked as such and removed from roles.


State and Territorial Exchange of Vital Events (STEVE)

What is it?
STEVE is operated by the National Association for Public Health Statistics (NAPHSIS) and sends death records that pertain to residents in other jurisdictions

Integration Benefit
If a death should happen while a person is out of state, the information will be sent to the jurisdiction of birth so that birth certificates can be flagged as 'deceased’. This information is helpful in removing deceased voter from registration systems.


Systematic Alien Verification for Entitlements Program (SAVE)

What is it?
A system administered by the U.S. Citizenship and Immigration Services, a component of the Department of Homeland Security. It is used primarily by benefits-granting agencies to verify an applicant’s immigration status or naturalized/derived citizenship.

Integration Benefit
Because SAVE can only verify immigration status or information at a particular point in time, and cannot determine whether someone is unlawfully present in the U.S, it is not currently widely used to confirm voter eligibility but more as information to look into further.
