About ABA NumbersDownload Bank Routing Numbers Database
A bank routing number, also known as an ABA number, is a nine digit code that is commonly found in the United States. It can be found on the bottom of financial tools such as checks, and it is used to denote the bank that the check is drawn on. In addition to this, the bank routing number is also used with the Automated Clearing House to transfer direct deposits. The bank routing number was created by the American Bankers Association in 1910. However, the creation of a new bank routing number is the responsibility of the Accuity, a firm that is connected to SourceMedia. This company will produce this list each year, and it has done this since 1911.
As of this writing, there are just over 29,000 ABA routing numbers being used by the public. The list that is published by Accuity can be found in the American Bankers Association Key to Routing Numbers. Every bank or financial company in the United States uses a nine digit number. To find this number, you will simply want to look on the bottom of a check. The financial company will be given the bank routing number from the Routing Number Administrative Board. The first two digits of the bank routing number should always fall between 00 and 12, 61 and 72, 80, or 21 and 32. The double zero is used by the government of the United States. The 01 and 12 range are the standard routing numbers, and the 21 through 32 range is given to what is called thrift institutions. However, it can still be used by virtually any financial company.
The range 61 through 72 is utilized to denote electronic transfers. The number 80 is used to denote traveler's checks. In addition to this, the first two numbers are used to represent the 12 banks that make up the Federal Reserve. The numbers 01, 61, and 21 are used to denote the Federal Reserve Bank of Boston. The numbers 62, 22, and 02 are used to denote the Federal Reserve Bank of New York. The numbers 03, 63, and 23 are used to denote the Federal Reserve Bank of Philadelphia. The other Federal Reserve Banks that are represented by the first two numbers are Cleveland, Atlanta, Richmond, Chicago, Kansas City, St. Louis, Dallas, and San Francisco. Before a nine digit number can be used as a bank routing number, it must first pass what is called the checksum test.
To achieve this, a mathematical formula is used. Once the nine digit number has passed the checksum test, it can be used as a bank routing number. If it does not pass the test, a new number must be generated and tested. The bank routing number is an important tool that bank customers will need when they want to open new accounts of transfer funds electronically. It is also needed for those who wish to receive payments via direct deposit. The bank routing number has made it easier for banks to process both electronic and traditional transactions.
