You can't search for supporters using their Supporter ID in the Fundraise Up dashboard. This is because it can lead to misunderstandings about supporter records’ purpose. Fundraise Up can detect which donations should be linked to which supporter by matching their email, but we don't have tools for merging, creating, or deduplicating supporters since we're not a CRM. It's best to perform those tasks in your CRM instead.

If you want to locate a supporter, try searching by their first name, last name, or email address for better results.
