Checks Letter (Informative Version) - Core Conversion
Going through a core conversion is a lot of work, and keeping your account holders informed is a top priority. Help keep customers or members informed about the core conversion as well as what products and services will be affected with this letter.

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 also affect our checks and deposit slips. With that said, we want you to be ready for how this will affect you. Below is a summary of what to expect.


You may use your checks during the core conversion process. However, you will need to make sure you have sufficient funds in your account to cover any checks you write during the core conversion.

You will not need to order new checks.
However, if your checking or savings account number is greater than 10 digits long, we will order new checks for you based on your previous order. Free of charge.

If your checking or savings account number is not greater than 10 digits long, you may continue using your current checks like normal.

Deposit Slips

Ordering new deposit slips will not be necessary.

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].
