What's Changing

Transitioning to a new core operating system is the most complex project a financial institution can undertake. While there will be a brief disruption to services during the conversion weekend and a few changes to how we do business, most banking processes will remain unaffected.


Members will receive two (2) statements. The first statement will reflect transaction activity from March 1 – March 19, but will not include any dividend information. The second statement will show transactions from March 20 – March 31, and will include dividend information. 

The format of the second statement will look different than the first statement. The new statement format showed information for all accounts a member is owner on. Members who previously received multiple account statements will now only receive one consolidated statement.

Business accounts with an EIN (tax ID number) will continue receiving a separate monthly business account statement.

Online and mobile banking, remote check deposit, and online bill pay, and shared branching was available at 9:00 am.

Members no longer identify accounts by a member number and account type suffix (i.e. S1, S12, L5, L57, etc.).

All AAFCU accounts will now be identified by a unique account number. This change is explained in more detail on the Accessing Your Account & Account Number Change page.
