MC Bank customers have until 2 a.m. Monday, Nov. 9 to schedule bill payments in the bank’s current system, and their old debit cards stop working Monday, Nov. 16, when the Louisiana bank’s new system goes live, according to the bank’s 2026 upgrade page. The switch begins Friday, Nov. 13 at 2 p.m. Central, and Zelle may stay unavailable until as late as Nov. 23.
Anyone who pays a utility, a mortgage or a monthly subscription through MC Bank’s online bill pay has the most riding on the calendar. The practical question is whether every payment and every card stored with a merchant will land on the right date once the new system takes over.

What happens to bill payments already in the queue?
The bank says payees convert automatically, but each converted payment keeps its previous delivery date as its new “send on” date, and that can make a bill late. Payments leave the account on the “send on” date, not the due date, so the date the new system carries over is the date the money moves.
Electronic payments need two business days to reach a payee, and checks need five. The bank says some payees are paid by check, so those bills should get an earlier send date. After the first login on Nov. 16, it tells customers to review every payee, amount and frequency.
When does the old debit card die, and where is the new one?
New debit cards were mailed Oct. 22 and are expected to arrive by Nov. 9. The new card is activated on or after Nov. 16, when customers also set a new PIN. The old card keeps working for purchases and ATM withdrawals through the upgrade weekend and stops on Nov. 16.
“Destroy it only after you activate the new card and complete at least one successful transaction,” the page says. Merchants that keep a card on file, such as streaming services, utilities, subscriptions and online retailers, need the new number and expiration date, and the card has to be added again to Apple Pay or Google Pay.
A customer whose card has not arrived by Nov. 9 is told to call the Upgrade Support Line for their area or visit a banking center:
- Morgan City: 985-464-7979
- New Orleans and surrounding areas: 504-910-1002
- Lafayette: 337-568-2770
- Baton Rouge: 225-576-8224
- Toll-free outside local calling areas: 888-954-8880
Digital banking assistance is at 985-384-2100.
What goes dark the weekend of Nov. 13?
At 2 p.m. Central that Friday, online banking, including Quicken and QuickBooks connections, the mobile app and Zelle become unavailable, and telephone banking is limited to inquiries. New online and mobile banking open Monday, Nov. 16 at 8 a.m. through an app called MCBANK Connect, and the previous app stops working.
Mobile deposits should be made in the current app before the Friday cutoff and resume in the new one on Nov. 16. Transaction history in the new system is limited to the most recent six months, down from 24, so the bank says to download statements and history before 2 p.m. on Nov. 13. Alerts do not convert, and customers are told to print their settings and set them up again.
Zelle returns no later than Nov. 23. People re-enroll with the same email address or mobile number, and any one-time or recurring Zelle payment scheduled after the Friday cutoff will not process.
Which parts of an account stay put?
Direct deposit and automatic payments, including payroll and Social Security, continue without interruption, the bank says. Customers keep using their current checks, and loan balances, rates, terms, due dates and payment addresses are unchanged. Account numbers, rates, terms and fees do not change, and access to the Community Cash and MoneyPass ATM networks stays the same.
Some account names do change: Hometown Value Checking becomes Basic Checking, Hometown Traditions Now becomes Interest Checking, and Personal Savings becomes Statement Savings. Banking centers keep the same locations, hours and bankers. M C Bank & Trust Company is a Louisiana-chartered state bank that opened in Morgan City in 1955 and runs 10 locations in southeast Louisiana, according to a December 2025 company release.
Is the money still insured while the system changes?
“Funds remain FDIC-insured up to the maximum allowed by law,” the bank’s page says. The Federal Deposit Insurance Corporation’s standard limit is $250,000 per depositor, per insured bank, for each ownership category, so a joint account and a single account at the same bank are counted separately.
The page also carries a plain warning: “MCBANK will never call, text, or email you to ask for your username, password, account number, PIN, or full card number.” Customers are told to download the app only from the official listing named MCBANK Connect, and to log in first with their current username, which must be used before Nov. 13 if they have not logged in during the past 13 months or it will not transfer.
