An informal and short human-readable definition of a concept, in terms of a 'one-liner'. Short description	Validates that postal codes follow official formatting schemas with correct spacing and separators.
Informal and comprehensive human-readable definition of a concept. Description	This category includes data quality rules that verify postal codes are formatted according to official postal code schemas, including proper spacing, hyphens, and presentation. While basic format validation checks syntax, schema validation ensures postal codes match the exact official presentation used by postal authorities. For example, Canadian postal codes should be formatted as 'K1A 0B1' with a space in the middle, UK postcodes as 'SW1A 1AA' with a space before the final three characters, and Netherlands postal codes as '1234 AB' with a space. Proper schema adherence is important for postal processing systems, official documentation, and integration with address validation services that expect specific formatting. These rules support the Representational_consistency dimension by ensuring postal codes match official presentation standards defined by postal authorities.

Post code format inaccurate (United States) REPRESENTATIONAL_CONSISTENCY	US (United States of America)	The US post code can contain a block of 5 digits or, for more accurate delivery, 9 digits in this format: NNNNN-NNNN. This is known as ZIP + 4. In case if the post code still has 5 or 9 digits but in other format then NNNNN-NNNN (a space instead of a hypthen, 9 digits without any delimiter etc.) then the rule is broken.
