Election Data Access and Request Form

Election Data Access and Request Form

Boulder County Elections is pleased to offer the below reports free of charge and available for download. All data comes from the Colorado Statewide Voter Registration Database (SCORE) and is provided in its original, unaltered form in a delimited text format. To review the data, you will need an appropriate software program (such as Microsoft Access or Excel).

All information contained in these reports is considered public under state law. Data files do not include voters who are protected as “confidential” voters in accordance with Colorado law (C.R.S. 24-72-204). Voter data is not provided for pre-registered voters under age 18 (C.R.S. 1-2-227). We will never disclose voters’ social security numbers, driver’s license or state-issued identification numbers, electronic copies of voter signatures, voter email addresses, or how a voter voted (which becomes anonymous during the ballot processing procedure when ballots are separated from their envelope). (C.R.S. 1-2-302, C.R.S. 1-1-110 and 1-7-105)

Boulder County Elections cannot provide data processing or technical support for these files. If you encounter an issue downloading a file, please contact us during normal business hours at 303-413-7740. The most recent file will always be posted. If for some reason a new file isn’t available from the Secretary of State’s website, the previous file will remain available.

This file is a list of voters (no confidential voters) with ballots that have been rejected for one of the following “curable” reasons: No signature, signature discrepancy, or valid identification required. Prior to the Friday before Election Day, the list includes ballots that are rejected for a curable reason that have been in that status for at least 72 hours. Beginning Friday after Election Day, the list is current without any lag time. If the voter provides the appropriate information, their ballot can be “cured” so that their ballot can be fully processed. As individuals “cure” their ballot envelopes, their names are automatically removed from the report.

Sample output fields include: Voter ID, Name, Year of Birth, Party, Phone, Residential Address, Mailing Address, Ballot Address, Mail Ballot Sent Date, Mail Ballot Received Date, Reject Reason

Frequency updated: This report is posted hourly between 7AM and 11PM beginning 19 days before an election. The last report will be posted at the end of the eighth day after election day.
