You must enter a tax registration number in a valid format. (ZX-885655)

Summary:

While entering the registration number for a legal reporting unit in Chile, I am getting an error message - "You must enter a tax registration number
in a valid format. (ZX-885655) The tax registration number isn't in the format that's used for registration numbers for the country of ."

I searched this error on this community and found some recommendations to go to "Manage Country Default Controls" and make "validation level" as NO and "Duplicate validation Level" as No validation. Even after making these changes, I am still getting the same error.

Really appreciate if you can share any suggestions to fix this issue.
