Powerful & Simple ACH Bank Verification

Initiating an ACH transaction requires a reliable and efficient method of bank account verification, a crucial and necessary step in the ACH transfer process. With Dwolla, businesses can choose between building a custom form to collect account and routing number information or using Instant Account Verification (IAV) to add and verify bank account information by passing Dwolla the online banking credentials.

Users without an online banking option can securely capture the necessary account and routing information to add and verify a bank account by using micro-deposits. If the user does have online banking credentials, ACH bank verification can be completed in seconds by searching for the financial institution and correctly entering the appropriate information.
