Saint Louis Zoo Charitable Contribution Policy

The Saint Louis Zoo is pleased to give back to the community by considering all charitable donation requests from qualified 501(c)(3) nonprofit organizations in the St. Louis area. It is our policy to reserve the right to grant the donation request as we see fit. Blocks of tickets or educational classes will not be donated.

Please keep in mind that while each request receives careful consideration, we regret that we are unable to accommodate all of the organizations that merit our assistance. The following groups are not eligible to receive complimentary pass donations:

  • Individuals or individual families
  • For-profit organizations
  • Political campaigns/fund-raisers

Due to the large number of requests we receive, allow at least 45 days for us to review and process your request. The donation will be sent via U.S. mail. All requests must be in writing. Phone solicitations will not be accepted.


To be considered for support, please follow the instructions below:

  • Attach the organization's formal letter of request for donation on the organization's official letterhead.
  • Include the Tax ID number or send a copy of the IRS determination letter.

Send the completed form and letter any one of the following ways:
