 Häufig gestellte Fragen

What is an ABA routing number?

An ABA routing number is a 9-digit code assigned by the American Bankers Association to identify financial institutions in the United States. It is used for wire transfers, direct deposits, and check processing.
How does the ABA checksum algorithm work?

The algorithm multiplies each digit by a weight (3, 7, 1, repeating), sums the products, and checks if the total is divisible by 10. If the remainder is 0, the routing number is valid.
What do the first two digits of a routing number mean?

The first two digits identify the Federal Reserve district that processes the routing number. Values range from 00 (US Government) to 80, with ranges 01-48 for paper checks and 61-80 for electronic transactions.
