If your nonprofit's name has not been updated with the IRS and GuideStar/Canada.ca, you must correct that before we can update it on our end.
Charities can CLAIM their nonprofit account on GuideStar by following the instructions Here. This will allow you to manage your profile easily. While you're there, make sure you OPT IN to receive donations from online sources.
