Informal and comprehensive human-readable definition of a concept. Description	This category encompasses data quality rules that validate postal codes against authoritative postal code databases for each country. While a postal code might be syntactically correct (proper format and structure), it may not actually exist as an assigned postal code in that country's postal system. Invalid postal codes can result from typos, outdated information (postal codes that have been retired), or completely fabricated values. Using non-existent postal codes leads to delivery failures, incorrect geographic assignment, and problems with address validation services. This validation is essential for ensuring mail deliverability and accurate geographic analysis. The rule supports the Accuracy dimension by verifying that postal codes are not just well-formed but actually exist in official postal registries.
