Millie makes it easy to discover and support causes you care about. With access to 7M+ nonprofits worldwide, you can quickly find a specific organization—or explore new ones by cause, location, or impact.
Quick Search: Find a Specific Nonprofit
Use the top search bar to look up a nonprofit by name or keyword.
- Start typing the organization’s name (e.g., CASA Boston).
- Millie will return exact matches first, plus related results.
- Click a nonprofit to view its profile, donate, or volunteer.
Pro tip: If keyword results are broad, use filters (below) to narrow things down.
Most Accurate Method: Search by EIN
If you’re having trouble finding a specific organization, search by EIN (Employer Identification Number).
- Find the nonprofit’s EIN (often listed on Google or the nonprofit’s website).
- Copy the EIN.
- Paste it directly into Millie’s search bar.
This returns a precise, one-to-one match, making it the best option for exact searches.
Discover New Nonprofits
Looking for something new to support? Millie offers powerful filters to help you explore.
Filter by:
- Category & Subcategory – Based on how nonprofits file taxes (e.g., Animals → Wildlife Preservation).
- Location – Search by city, distance, country, or globally.
- Favorites – Quickly revisit nonprofits you’ve saved.
- Matching Eligibility – See nonprofits eligible for your organization’s matching program.
- Badges – Highlight nonprofits by characteristics like newer organizations or highly engaged communities.
You can stack filters to refine your results even further.
Saving Your Favorite Nonprofits
Found a nonprofit you love? 💕 Favorites make it quick to find the organizations you support often, or ones you want to come back to later, like during year-end giving season. 🎁
- Open any nonprofit's profile.
- Click the Add to Favorites button below the organization’s name.
- Changed your mind? No problem! To remove a favorite, open the profile and click the button again.
✨ To see your saved nonprofits, go to the Donate page and turn on the Favorites filter. You can combine it with other filters, like category or Matching Eligibility, to narrow your list. Favorites are private; coworkers and admins can't see which nonprofits you've saved.
