Address validation checks format and completeness — whether an address is properly structured and meets postal standards. Address verification goes further by confirming the address exists and is linked to a real recipient. For example, validating a Jersey address means checking that the postal code follows the JE9 9AA format and appears after city. Verifying it means confirming that a real recipient lives or operates at that specific address. Most businesses benefit from both: validation broadly for data quality, and verification for higher-risk situations like compliance or fraud prevention.
