The problem

Invalid routing numbers cause ACH returns, incurring fees and delays. Manual validation is error-prone and time-consuming.

The solution

Validate routing numbers in real-time as users enter them. Display the bank name for confirmation, reducing errors before submission.

Everything this unlocks.

Instant validation feedback
