Third Coast Bank and Heritage Bank are coming together! 

We are excited to begin the process of transitioning Heritage Bank to Third Coast Bank.  With this conversion comes several changes, and we want to make sure you feel informed and confident - every step of the way.

You have Questions.  We have Answers.



When is Conversion?  

System conversion will take place beginning on
Friday, July 10th at 3:00 pm, and will move to Third Coast Bank on Monday, July 13th at 8:00 am.

What is my Account Number?

Your checking, CD, money market, and savings account number will change to a 10-digit number.  Your loan account number will not change.

What is my Account Type?

Your account(s) will be transferred to a Third Coast Bank account(s) that most closely fits the features and benefits of your existing account(s).  Review the Personal and Business Conversion Guides below.  However, if you determine that a different account is more appropriate, simply call (855) 485-0600 or visit your local branch to change your account type.

Will I need new Checks?

Until conversion day of July 13th, please continue to use your Heritage or formerly Nixon State Bank checks.  If you have existing check stock, you may continue to use it for a period of time post-conversion (the cut-off date is to be determined by the Federal Reserve Bank).  However, we encourage you to order new checks with our Third Coast Bank routing number #113094149 and your new account number.  We will provide your first order of bank stock checks for Free!  Please call (855) 485-0600 or visit your local branch.

Will I get a new Debit Card?
