Rahatunnus

Rahatunnus is a Finnish term that can refer to a unique identifier associated with money or a monetary transaction. The exact meaning and usage vary by context, and rahatunnus is not a formal term defined in Finnish financial regulation. In practical systems, it is used to track, reference, or reconcile monetary items within accounting or payment processes.

In typical applications, a rahatunnus functions as a transaction identifier or payment token. It may be generated by a bank, payment processor, invoice issuer, or digital wallet and attached to a payment record, ledger entry, or asset transfer. The identifier helps ensure traceability and reduces ambiguity when reconciling payments or transfers.

Because the concept is not standardized, the format of a rahatunnus can vary. It may be numeric or alphanumeric, include check digits, and embed metadata such as issuer, date, or transaction type. In some contexts, the term is used interchangeably with a reference number (viitenumero) or a token representing monetary value.

Typical uses include linking a payment to an invoice, matching incoming funds to customer accounts, or representing a digital value in a wallet. In electronic invoicing, a rahatunnus may appear on receipts and be used in search and reconciliation workflows.

Notes and definitions of rahatunnus are system-dependent, and not all organizations use the term. When encountered, its precise meaning should be documented within the relevant software or process documentation. Related concepts include viitenumero (reference number), transaction ID, and payment token.
