Online Banking Letter (Informative Version) - Core Conversion
Going through a core conversion is a lot of work. Help keep customers or members informed about the core conversion as well as what products and services will be affected.

Dear [Customer’s/Member’s First Name],

We are excited to announce that we are converting to a new core banking system starting on [INSERT DATE] through [INSERT DATE]. We decided to change our core system so we may continue to provide you with safe, secure products and services all while utilizing the newest technology.

This core conversion will affect our Online Banking service for a short period of time, but in a good way. The new and improved Online Banking is safer and more secure than our current service. It will also offer a variety of new tools that we weren’t able to offer before, like [INSERT A FEW NEW TOOLS].

As mentioned above, there will be some changes heading your way, and we want you to be ready for them. Below is a summary of what to expect during the core conversion with regards to online banking.

Online Banking Availability

Our Online Banking service will be down from [INSERT TIME AND DAY SYSTEM WILL BE UNAVAILABLE] to [INSERT END TIME AND DAY SYSTEM WILL BE UNAVAILABLE]. It will become available again on [INSERT DATE], and we can’t wait for you to check it out.

E-Statement History

You will not have access to your e-statement history after [INSERT DATE]. We highly recommend downloading and printing a year’s worth of statements for your records. If you have any questions about e-statements or how to download them, please call us at [INSERT PHONE NUMBER].

Username and Password Changes

The new Online Banking service comes with enhanced security, and, because of this, you will need to change your username and password. You can do this by going to our Online Banking service after [INSERT DATE WHEN AN ACCOUNT HOLDER CAN ACCESS ONLINE BANKING AGAIN] and type in your current username and password. Our system will then prompt you to create a new username and password as well as select security questions.

Bill Pay

Our Bill Pay service is getting a new look and feel, and we can’t wait for you to see it. Please note that you will not have access to Online Bill Pay during the core conversion process. We recommend scheduling all Online Bill Payments to be paid before [INSERT LAST DAY THEY SHOULD SCHEDULE AN ONLINE BILL PAYMENT]. This will ensure a timely payment.

Telephone Banking

Our Telephone Banking will also be unavailable during the core conversion. It will be available again starting on [INSERT DATE TELEPHONE BANKING WILL BE AVAILABLE AGAIN].

We are looking forward to the new changes, and we hope you are too. If you have any questions, please contact us at [INSERT PHONE NUMBER] or visit our website at [INSERT WEBSITE URL – OR SPECIFIC CORE CONVERSION FAQS PAGE ON YOUR SITE].
