Adressdata

Adressdata, often translated as address data, refers to structured information that identifies the location of a person or organization. It typically describes a physical street address used for mail or delivery, but may also include geographic coordinates and administrative areas used for routing and governance.

Core components generally include street name, house number, city or locality, postal code, and country. Additional elements may include apartment or unit numbers, floor, and regional subdivisions. Geographic coordinates (latitude and longitude) are frequently stored alongside to support mapping and routing.

Standards and formats: address data is governed by both national postal conventions and international standards. Common representations include vCard and schema.org's PostalAddress, while formal addressing standards are covered by ISO 19160 and related geoinformation standards. In practice, organisations may apply country-specific addressing rules and normalization procedures to ensure consistency across systems.

Data sources and quality: address records come from official registries, postal operators, cadasters, and sometimes open datasets. Quality concerns include completeness, consistency, spelling variations, multilingual representations, and changes over time. Regular normalization, validation, and deduplication are common practices to maintain reliable address data.

Uses: address data supports mail delivery, logistics, emergency services, customer verification, geocoding, and spatial analysis. It enables accurate routing, service eligibility checks, and demographic studies. Privacy considerations require treating addresses as personal data under laws such as the GDPR, with appropriate safeguards and data minimization.

Challenges include updating address changes, handling P.O. boxes, rural addresses, multilingual formats, and different country conventions. Effective governance relies on data lineage, update frequency, versioning, and secure storage.
