Your New AACU Account Information


On November 2

HFCU members will officially have AACU accounts. We have included some important information about your new AACU accounts to make the transition as seamless as possible for you. 

AACU's Routing Number: 307070021



AACU Account Numbers

  • Each account will have a new unique account number. You will no longer use your member number to access your accounts.
  • If you did not open an AACU account prior to the data conversion, you will need to enroll and login to AACU's online banking to obtain your new account numbers. To enroll in online banking, please follow the steps listed on the What Do I Need To Do page. 

MICR Numbers

  • Your checking account number is your new dedicated MICR number. You will use this new MICR number when setting up any direct deposit and ACH transactions.
  • What is a MICR number? A MICR (magnetic ink character recognition) line refers to the line of numbers appearing at the bottom of a check. The MICR number is the account number listed on the bottom of your checks.

Online and Mobile Banking

Debit Cards

  • If you did not open an AACU account and attain an AACU debit card prior to the data conversion on October 31, you will automatically be issued a new AACU debit card and it will arrive by mail in 7-10 business days.
  • You can also visit any branch location on, or after, November 2, to receive an instant issue debit card.

Account Statements

  • AACU statements consolidate and display account information for all accounts of which you are the primary owner.
  • Account statements can be accessed electronically by enrolling in eStatements through online banking, or you will receive them by mail if you have elected to receive paper statements.
