- Each bank may have up to four additional routing numbers beyond the âprincipal office number.â
- The ABAâs Routing Number Administrative Board manages the assignment of routing numbers.
- Each nine-digit routing number has three components:
- Federal Reserve routing symbol. These are the first four digits of the routing number. If the first two numbers of a routing number are 00, the routing number is for a check or draft from the U.S. Government. Banks use routing numbers that start with the first digits of 01-12. Travelerâs checks have routing numbers that begin with 80. Most of the other first two-digit series are âreserved for future use,â determined by the ABA Routing Number Administrative Board.
- ABA institution identifier. The next four digits are the unique identifier of the particular bank/financial institution.
- Check digit. The last number is the check digit, which helps banks avoid transaction errors.
Is There A Wire Routing Number
If youre receiving a domestic wire transfer within the US, you might need to give your payer a different routing number than the one on your checkbook.
The wire routing number, still technically an ABA routing number, is a 9-digit code like the ones already discussed.
Youll need to check directly with your bank what number you should give it might be the same as the ACH number and/or the routing number on your checkbook, but it might not.
If youre receiving a wire transfer from another country, you might not need a routing number at all. Instead, its likely youll need to give them your banks SWIFT code, which you can find out from them or look up online.

How Does An International Wire Transfer Work
The principle of international wire transfers is exactly the same as for domestic ones, but the process is a lot more complicated and often involves intermediary banks connecting the sender to the receiver.
The basic process is that your money travels from your bank to the recipients bank, via 1 – 3 intermediary banks, through the SWIFT network.
This is reliable, but can be slow and the intermediary banks can also deduct a fee as they process the payments, meaning your recipient gets less than expected in the end.
If youre receiving an international wire transfer, you might need to provide a SWIFT code rather than a routing number. Check with your bank about what they use, or you can look it up online.

Aba Numbers And International Transfers
Nine-digit routing numbers are only used within the US, while most other countries use an IBAN instead. If youre abroad and wish to transfer funds into a US bank account, youll need to provide the ABA number. For international payments youll usually need the accounts BIC/SWIFT code as well, which can be found on the banks website or calling customer service.
How Aba Numbers Help Process Checks
Since the 1960s, the ABA number has played an instrumental part in significantly speeding up check processing. Additionally, with the passage of the Check 21 Act in 2003, physical checks that needed to travel by airplane and truck to reach banks could now be submitted and cleared electronically. As a result, funds clear much more quickly, and consumers no longer have the luxury of “playing the float” or issuing a check a few days before they actually have the funds in their account.

-
Number 7: The seventh digit corresponds with the banks Federal Reserve check processing center.
-
Number 8: This digit lets you know which Federal Reserve district the bank is located in.
-
Number 9: The final digit in an ABA number is a checksum, which is a mathematical sum of the first eight numbers. The final result should be equal to this checksum or else the transaction will be rerouted.

Your ABA number is usually accompanied by your account number as the information given to whoever is trying to issue a payment. The rest of the work is commonly handled by the bank, a biller or an employer.
In case a bank closes or is taken up in a merger or acquisition, you might receive new ABA numbers. Sometimes you dont have to use them right away. You may continue using the old numbers indefinitely, or at least until request for new checks and services.
The ABA number is made up of five parts, each with its own purpose:
Part | |
---|---|
This one shows the Federal Reserve district the bank is in. | |

It is necessary for everybody to be familiar with the basics of bank numbering systems this can be simplified by identifying the different elements. Two of the universal codes are the ABA Transit Number, or ABA Number, and the Routing Transit Number , or Routing number. It is rather easy to distinguish one from the other based on the code construction, length, and location.
Use The Correct Number
Your bank may operate under several ABA numbers, so its essential to identify the one specific to your account. ABA numbers may differ depending on where you opened your account, and bank mergers can result in multiple codes for the same bank. Some banks also use separate ABA numbers for wire transfers vs. direct deposit or ACH transactions.
Even if you know the correct number for ordering checks, you might need to use a different number for wire transfers or electronic bill payments. When in doubt, ask a customer service representative at your bank which number to use.

The MICR routing number consists of 9 digits:
- XXXXYYYYC
where XXXX is Federal Reserve Routing Symbol, YYYY is ABA Institution Identifier,and C is the check digit.
Federal Reserve
The Federal Reserve uses the ABA RTN system for processing its customers’ payments. The ABA RTNs were originally assigned in the systematic way outlined below, reflecting a financial institution’s geographical location and internal handling by the Federal Reserve. Following consolidation of the Federal Reserve’s check processing facilities, and the consolidation in the banking industry, the RTN a financial institution uses may not reflect the “Fed District” where the financial institution’s place of business is located. Check processing is now centralized at the Federal Reserve Bank of Atlanta.
The first two digits of the nine digit RTN must be in the ranges 00 through 12, 21 through 32, 61 through 72, or 80.
The digits are assigned as follows:

ABA Institution Identifier
The fifth through eighth digits constitute the bank’s unique ABA identity within the given Federal Reserve district.
