About The Project

Parsing out information from ABA numbers can be tricky without the use of online lookup tools. This project aims to create an offline and open-source alternative. When used, the package can be used to validate ABA numbers and if valid, return information about the number including:

• Bank Name
• Bank Address
• Bank State
• Bank Phone Number

ABA Number Validation:

Check digit
The ninth, check digit provides a checksum test using a position-weighted sum of each of the digits. High-speed check-sorting equipment will typically verify the checksum and if it fails, route the item to a reject pocket for manual examination, repair, and re-sorting. Mis-routings to an incorrect bank are thus greatly reduced.

The following condition must hold:
(3(d1 + d4 + d7) + 7(d2 + d5 + d8) + (d3 + d6 + d9)) mod 10 = 0
