Property	Value
A technical identifier, unique in a certain context. Technical key	POSTAL_CODE_SCHEMA
The human-friendly name shown for this concept in the user interface, used instead of the technical name to improve readability and understanding. Display name	Postal code schema
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.
