Increase Account Numbers API is one of 56 APIs that [Increase](https://apis.io/providers/increase/) publishes on the [APIs.io](https://apis.io/) network, described by a machine-readable OpenAPI specification. Tagged areas include Account Numbers. The published artifact set on APIs.io includes an OpenAPI specification and API documentation.

Each account can have multiple account and routing numbers. We recommend that you use a set per vendor. This is similar to how you use different passwords for different websites. Account numbers can also be used to seamlessly reconcile inbound payments. Generating a unique account number per vendor ensures you always know the originator of an incoming payment.
