Korttinumeron

Korttinumeron is the genitive singular form of the Finnish compound noun korttinumero, which means “card number.” The term is used in contexts where ownership, specification, or relation to a card number is being described, such as in security, banking, or documentation. In practice, korttinumeron appears in sentences to refer to the card number itself or to actions involving it.

Etymology and morphology: korttinumero combines kortti (card) and numero (number), with the entire compound treated as a single noun. Finnish forms the genitive by adding the suffix -n, producing korttinumeron. This form is used when the card number is the object, possession, or part of a broader noun phrase, for example korttinumeron paljastuminen (the disclosure of the card number) or korttinumeron säilyttäminen (the safeguarding of the card number).

Usage and examples: Korttinumeron is common in written material related to finance, identity verification, and security. Examples include: “Asiakas antoi korttinumeron turvattomasti” (The customer gave the card number insecurely) and “Korttinumeron suojaaminen on tärkeää” (Protecting the card number is important). The genitive form is rarely used outside formal or technical contexts but appears in user guides, policy documents, and security advisories.
