Requirements To Appear on AmazonSmile
Here are the requirements your organization must meet to be listed on AmazonSmile. Your nonprofit organization:
is qualified under Section 501(c)(3)
is a public charitable organization and not a private foundation
is not supporting organizations, unless identified specifically as a Type I, Type II, or functionally integrated Type III supporting organization
is headquartered in the United States (the 50 States and the District of Columbia)
My Organization Does Not Appear on AmazonSmile
Once your organization appears on GuideStar, then you will automatically be opted in for third party donations from AmazonSmile.
We send updated information on nonprofits to AmazonSmile at the end of the month, usually around the 22nd. If you are a new organization, recently opted-in to receive donations from our partners or made updates to your profile, you can expect your organization to appear on AmazonSmile the first week of the month.

Nonprofit Profile Information on AmazonSmile

Searching for Nonprofits on AmazonSmile by their DBA
If an organization has a DBA listed on their nonprofit profile and it is not in the title/name of your organization, the DBA will not appear on AmazonSmile's website.
However, if an organization is registered at org.amazon.com and they search for their DBA, the organization will appear but show as the registered name or the name that appears on your organization's profile page. The same will happen when supporters search for the DBA name of your organization.
