Routing Transit Number (RTN)


A Routing Transit Number (RTN), also known as American Bankers Association (ABA) number, is a nine-digit code used in the United States to identify financial institutions. It is used for processing transactions such as direct deposits, electronic payments, and wire transfers. Each financial institution has a unique RTN that distinguishes it from other banks.


The phonetic pronunciation of “Routing Transit Number (RTN)” is “ROO-ting TRAAN-zit NUHM-ber (aahr-tee-en)”.

Key Takeaways

  1. Identification: Routing transit numbers (RTN) are nine-digit codes that help identify a financial institution in a transaction. These numbers were developed by the American Bankers Association (ABA) and are unique to each bank.
  2. Locale Specific: A bank may have more than one routing number. This is because the numbers may be determined by factors such as the geographical location of the account holder or the specific task they wish to accomplish (such as wire transfers, electronic transactions, etc).
  3. Importance in Transactions: Routing transit numbers are necessary for the processing of wire transfers, direct deposits and electronic payments, checks processing, and online banking transactions. They enable the correct routing of funds between banks.


The Routing Transit Number (RTN) is a crucial identifier in banking and finance for both the financial institution and its customers. It is a nine-digit numeric code used in the United States to identify a financial institution in a transaction. As a fundamental element in the process of sending and receiving money, this code ensures accurate, secure, and swift transactions such as direct deposits, electronic payments, and wire transfers. Without the correct RTN, the processing of transactions could be delayed or even misdirected, potentially leading to financial losses or other difficulties. Hence, the importance of the Routing Transit Number lies in its role in enabling efficient and effective monetary transactions.


The Routing Transit Number (RTN) serves a crucial role in identifying the specific financial institution involved in a transaction. Generally utilized in the United States, this nine-digit number becomes a fundamental aspect in various transactions such as direct deposits, electronic payments, and wire transfers. The RTN allows the streamlined processing and routing of these transactions to the correct bank, ensuring that the funds are accurately and seamlessly transferred between accounts.The use of RTN is integral in today’s digital age where economic activities remarkably rely on electronic fund transfers. Not only does it provide a structured channel for both domestic and international transfers, but also fortifies the security measures by discerning a legitimate financial institution involved in the transaction. Therefore, the Routing Transit Number is simply not a mere series of digits but a key player promoting precise, efficient, and secure financial operations.


1. Direct Deposits: A specific example of RTN usage is when an employer uses direct deposits to pay employees. To set up this service, the employer needs the bank’s RTN and the employee’s account number. The RTN is used to identify the employee’s bank and ensure the funds are sent to the correct place.2. Automatic Bill Payments: In another example, when you want to set up automatic bill payments from your checking account to pay for utilities, mortgage, or any other regular payments, the service provider will ask for your bank’s Routing Transit Number along with your account number. This RTN helps the service provider to direct your payments correctly through the ACH network.3. Funds Transfer: Transferring money from one bank to another also requires a Routing Transit Number. Whether you’re transferring money online or through wire transfer, the RTN of your bank and the recipient’s bank (if different) are needed. For instance, if you’re sending money from Bank of America in New York to a Chase Bank account in California, you’ll need both the RTN for Bank of America and the RTN for Chase Bank to complete the transaction.
