How can a non-U.S. organization obtain a D-U-N-S number for Apple Business Manager verification?

How can I obtain a D-U-N-S number for an organization that’s not based in the United States?

I’m trying to verify an Apple Business Manager account, but the process requires a D-U-N-S number. When I try to apply for one, it says that only U.S.-based organizations are eligible.
