Introduction
A routing number, also known as a routing transit number (RTN), is a nine-digit code used to identify financial institutions in the United States. It serves a critical role in ensuring that funds are correctly transferred between banks, whether through cheques, electronic funds transfers (EFTs), or wire transfers. The equivalent in the United Kingdom is the sort code.
Structure and Types of Routing Numbers
Routing numbers follow a specific format and are divided into three main segments:
- Federal Reserve Routing Symbol: The first four digits of the routing number indicate the Federal Reserve district and regional processing center that services the bank.
- ABA Institution Identifier: The next four digits represent the unique identification code assigned to the financial institution by the ABA.
- Check Digit: The last digit is a checksum that validates the routing number, helping to detect any transcription errors.
