Last updated: April 1, 2026
Key Facts
- PZN stands for 'Pharmazentralnummer' which means 'Pharmacy Central Number' in English
- It's an 8-digit numeric code assigned by the Information Centre for Medicines in Germany (ABDA)
- PZN numbers are required for all approved medications sold in German pharmacies
- The system includes a check digit calculation that validates PZN number accuracy
- PZN is used throughout German healthcare for prescription processing, billing, and inventory management
Overview
The PZN (Pharmazentralnummer) is Germany's standardized numbering system for pharmaceutical products. Managed by the ABDA (Bundesvereinigung Deutscher Apothekerverbände), the system assigns unique numerical identifiers to all approved medications sold in German pharmacies. This centralized system ensures accurate tracking, billing, and distribution of pharmaceuticals throughout the German healthcare system.
What PZN Numbers Identify
Each PZN number uniquely identifies a specific pharmaceutical product, including:
- Active Ingredients - The medication's chemical components
- Dosage and Form - Strength, tablet form, injection solution, etc.
- Package Size - Number of doses or volume in the package
- Manufacturer - The pharmaceutical company producing it
- Active Status - Whether the medication is currently available
Structure and Validation
The PZN is an 8-digit number where the first seven digits identify the product and the eighth digit is a check digit. This check digit uses a mathematical algorithm to verify that the number is valid, preventing data entry errors in pharmacy systems. The system is designed for easy integration into computerized pharmacy management and dispensing systems.
Use in German Healthcare
PZN numbers are essential to German pharmacy operations. Pharmacists use them to:
- Identify and retrieve medications from inventory
- Process doctor prescriptions accurately
- Bill insurance companies correctly
- Track medication side effects and recall information
- Manage medication interactions and contraindications
Historical Context
The PZN system was established in 1978 and has become the fundamental pharmaceutical identification standard in Germany. It remains separate from international systems like EAN barcodes, though many products display both. The system continues to evolve with digital healthcare integration in Germany and across Europe.
