During the upgrade timeframe, the MobiMoney APP, and our ATMs located at our New Year Branch and Queens Branch will not be available for your use.

We apologize in advance for any inconvenience this interruption and system changes may cause you. We assure our best efforts to limit the impact to the debit card services during upgrade timeframe and going forward.

You may also notice the following changes after the upgrade is completed on April 17th 2023:

  • New Customer Service Numbers

Card Activation & PIN Change

The existing phone number 800-216-4223 on the back of your card will still work and your call will be automatically transferred to this new number effective from 4/17/2023.

  • Changes on MobiMoney APP

The Account Details Page in this APP, which currently shows checking and savings accounts information, will no longer be available after the upgrade.
