erännumero

Erännumero is a batch or lot number used in Finnish manufacturing and logistics. It serves as a unique identifier for a group of units produced in a single manufacturing run, linking products to their production data, materials used, production date, and quality records.

The erännumero is typically printed or affixed on packaging or labels and stored in enterprise systems such as inventory management or ERP. It enables traceability across the supply chain, supports quality assurance, and facilitates product recalls by allowing all units from a given batch to be identified quickly.

Etymology and usage: the term combines Finnish erä (batch, lot) with numero (number). In Finnish industry, erännumero is commonly translated as batch number or lot number in English. The concept is similar to batch or lot codes used in other languages and is used alongside serial numbers when applicable to identify individual items within a batch.

Regulatory and practical aspects: many sectors require batch numbering on labels for traceability; manufacturers maintain batch records that document inputs, manufacturing conditions, and test results. In practice, erännumero supports recalls, stock rotation, and quality investigations.
