Routing Numbers

Modern Treasury validates all routing numbers that are supplied when creating a Routing Detail object. This API endpoint can be used to perform the same validation without creating a routing detail.

Some common use cases for this are:

  • You want to validate a routing number the user has entered prior to creating an external account for them.
  • You want to do a real-time validation of the routing number that the user is entering in your user interface.
  • You want to display the name of the bank that corresponds to the routing number in your user interface.
  • You need to validate that the routing number the user provides works for the type of payment you are doing. For example, not all ABA routing numbers work for both ACH and wire payments.

You may use this endpoint to validate a variety of types of routing numbers. Refer to the routing_number_type row below to see which routing number types you may validate.
