Organizations that add themselves to the YourCause database should be able to update their address if they move their offices, it's not uncommon. They should not be forced to create another organization record with the same registration number but with an updated address. This will result in multiple organization records with different addresses for the same organization, and at least one, maybe more of the addresses will be obsolete. Presumably an applicant could still mistakenly select an organization record that's showing the wrong address. The problem could be minimized by allowing them to change their address if it's not coming from one of the vetting registries.
Additionally, there is no guidance on the application search screen for non-vetted applicant organizations to know that they can and must add a new organization record with a new address if the organization's offices are relocated.
