Referenzcode

Referenzcode is a term used to describe a code that uniquely identifies a reference to a document, object, transaction, or data item within a system. It functions as a stable, machine- and human-readable identifier that can be used to retrieve, cross-reference, or audit records. The exact meaning of a Referenzcode depends on context, but it typically serves as a primary key or connector between components such as invoices, orders, or records.

A Referenzcode is usually designed to be unique within a defined scope (e.g., an organization, system, or dataset). Formats are variable and may be alphanumeric, include separators, and sometimes encode information such as date or origin. Common features include deterministic generation (to reproduce or validate) and protection against obvious disclosure of sensitive data. In practice, codes are generated automatically by software (e.g., order management, ERP, CRM) or entered according to a defined scheme by users.

Referenzcodes appear in many domains. In finance and accounting, a payment or invoice may include a Referenzcode to link the payment to the corresponding invoice. In inventory and logistics, products or shipments may carry a Referenzcode to identify the lot, batch, or order. In software and data exchange, resources, transactions, or API calls may be tagged with a Referenzcode to enable traceability and auditing.

Guidelines for creating Referenzcodes include ensuring uniqueness, readability, stable allocation, and accompanying documentation of the coding scheme. See also Referenznummer or Identifikator.
