VCn

VCN is an acronym that can refer to several concepts in finance and computing. The two most common usages are Virtual Card Number and Virtual Cloud Network, notably in Oracle Cloud Infrastructure.

Virtual Card Number: A virtual card number is a temporary card identifier issued by financial institutions for online or remote transactions. It typically represents a one-time or limited-use substitute for the primary card number. The cardholder uses the VCN with a merchant, and the issuer routes payment from the real account. Features may include expiry, merchant-specific limits, and the option to freeze or delete the VCN. Benefits include reducing exposure of the actual card number, easier cancellation of compromised cards, and control over spending. Limitations include compatibility with some merchants, issues with recurring payments, and potential incompatibility with certain wallets or loyalty programs. A VCN does not create new funds; it simply masks the underlying card data.

Virtual Cloud Network: In Oracle Cloud Infrastructure, a Virtual Cloud Network (VCN) is a customizable private network that provides connectivity between OCI resources and to on-premises networks. A VCN contains compartments, subnets (public and private), route tables, security lists, and gateways, enabling traffic control and segmentation. You can establish internet connectivity, VPN or FastConnect for private links, and VCN peering to connect with other tenants. The design supports subnet-level security, private IP addressing, and integration with other Oracle services.

Because VCN is an acronym used in different domains, the intended meaning should be inferred from context.
