The "F15Z interface" is a standardized data transmission format used in the German public sector, particularly within the field of population registration. It facilitates the structured, electronic exchange of data between municipal registration offices and governmental authorities (e.g., statistical offices, local registration authorities). Defined by the Federal Office of Administration, the format is based on an XML schema and supports the transmission of statistics, inventory data, and updates as part of legally mandated reporting requirements.
Data exchange with authorities: Automated sending and receiving of F15Z-compliant messages (e.g., arrivals, departures, corrections, inventory reports).
Validation and verification: Checking the message structure and content for conformity with the F15Z XML schema.
Logging: Recording all transmitted and received datasets including timestamps and validation results.
Encryption and digital signature: Secure transmission using electronic signatures and encryption in compliance with official standards.
Interface management: Administration of endpoints, communication protocols (e.g., OSCI), and transmission paths.
Version control: Support for multiple F15Z schema versions to ensure compatibility during system updates.
Error handling: Detection, logging, and processing of transmission errors or data inconsistencies.
A municipal registration office transmits population inventory data automatically to the state statistical office using the F15Z format.
A software module reconciles change notifications regarding citizen movements with central databases.
An IT service provider implements the F15Z interface in a population registration software to ensure legally compliant communication with government agencies.
A specialist application regularly sends correction notifications to the Federal Office of Administration via the F15Z interface.
