Frequently asked questions
- How does the validation works?
We check the length of the routing number. ABA numbers have 9 digits, so we verify if there are only 9 digits. After that, we calculate the checksum of the first eight digits. If the nine-digit is equal with the result of checksum this means that the routing number is valid.
- What means ABA RTN?
ABA stands for American Bankers Association and RTN stands for Routing Transit Number. ABA and RTN are the same.
