Geography validation is a feature that enables you to validate the address information entered for a location against the geography hierarchy defined for a country. You can set the Geography Validation for Country option to one of the following values:

No Validation: No validation is performed on the address information.

Warning: A warning message is displayed if the address information does not match the geography hierarchy, but the user can still save the address.

Error: An error message is displayed if the address information does not match the geography hierarchy, and the user cannot save the address until the error is corrected. To ensure that only valid addresses are entered in the system, you should set the Geography Validation for Country option to Error. This will prevent users from saving erroneous address data and enforce data quality and accuracy. References:
