Firstbank Corporation Alma Log In has moved to Mercantile Bank of Michigan. Firstbank Corporation, the former Alma-based holding company, merged into Mercantile Bank Corporation on June 1, 2014. Its Firstbank and Keystone Community Bank subsidiaries were then consolidated into Mercantile Bank of Michigan.
Do not use FirstBank Colorado or another similarly named bank for an old Michigan account. Former Firstbank Corporation customers should start with Mercantile Bank’s current MercBank Online or mobile banking and ask Mercantile to trace any account that does not appear.
How to Log In
There is no separate current Firstbank Corporation Alma Log In. Use Mercantile Bank only when the old relationship was with the Alma, Michigan company. Have the current Mercantile Login ID and password ready, or use the bank’s recovery tools for the converted profile.
MercBank Online
- Type Mercantile Bank Michigan into your browser and open its current official website yourself.
- Choose Online Banking Login and confirm that the screen says MercBank Online.
- Enter the current Mercantile Login ID.
- Complete the password and any Secure Access Code requested for the session you started.
- Confirm that the former Firstbank accounts, loans, and recent activity appear.
- Log out when finished and contact Mercantile before creating another enrollment for a missing converted product.
MercMobile banking
- Install or open Mercantile Bank’s official mobile app from the current store listing.
- Use the same current Mercantile Online Banking profile.
- Complete any device or Secure Access Code verification requested by the bank.
- Set up biometric access only after a normal login succeeds on your own trusted device.
- Check balances and transaction history before making a transfer or mobile deposit.
- If the app does not show an old Firstbank product, use MercBank Online once and then ask support to trace it.
What Happened to Firstbank Corporation?
Federal Reserve records identify Firstbank Corporation as the Alma, Michigan holding company that owned Firstbank and Keystone Community Bank. The Federal Reserve approved Mercantile Bank Corporation’s acquisition in May 2014, and securities filings record the merger as effective on June 1, 2014.
Mercantile became the surviving holding company. The bank subsidiaries were consolidated into Mercantile Bank of Michigan, so Firstbank Corporation no longer has a separate customer portal. A website for another institution with FirstBank in its name is not the successor merely because the spelling looks familiar.
- Old institution: Firstbank Corporation, headquartered in Alma, Michigan.
- Merger partner and survivor: Mercantile Bank Corporation.
- Current customer bank: Mercantile Bank of Michigan.
- Merger effective date: June 1, 2014.
- Wrong route to avoid: unrelated FirstBank institutions in Colorado, Puerto Rico, or another state.
Recover the Mercantile Profile
Mercantile’s current login page provides separate Forgot Username and Forgot Password options. The bank says the Login ID recovery tool asks security questions. For a password reset, choose Forgot Password and complete the Secure Access Code process before creating the replacement password.
Mercantile allows three login attempts before the profile locks. If it is already locked, call the eBanking team instead of trying more passwords. If the login works but an old Firstbank account is missing, ask Mercantile to trace the converted product under the existing customer profile rather than making a duplicate enrollment.
- Use Forgot Username when the Mercantile Login ID is unknown.
- Use Forgot Password once and complete the Secure Access Code check.
- Stop after a lockout and call the Mercantile eBanking team.
- Confirm that the bank has the current phone and email for security codes.
- Ask support to link or trace a missing former Firstbank account or loan.
Confirm the Right Michigan Account
Old papers may say Firstbank Corporation, Firstbank – Alma, Firstbank – Mt. Pleasant, Firstbank – West Branch, Firstbank – Lakeview, or Keystone Community Bank. Those names were part of the same Firstbank group described in the merger records. Give the exact former name and account type when contacting Mercantile.
The current Mercantile routing number shown by the bank is 072413829, but do not replace instructions on an old check, wire, ACH authorization, or loan document without confirming the specific transaction with Mercantile. A historical relationship does not prove that every old number remains usable.
Known Issues & Common Problems
Wrong FirstBank website: The Alma company merged into Mercantile. Do not enter Michigan account details at an unrelated FirstBank site.
Mercantile Login ID forgotten: Use Forgot Username and complete Mercantile’s security-question recovery process.
Password rejected: Use Forgot Password once and complete the Secure Access Code verification before setting a new password.
Profile locked: Mercantile says Online Banking locks after three failed attempts. Call 800-453-8700 for eBanking help.
Converted account missing: Ask Mercantile to trace the old Firstbank name, account or loan under the existing profile before enrolling again.
Transaction status unclear: Check current and pending activity before repeating a transfer, bill payment, or mobile deposit.
Firstbank Corporation Alma Log In problems usually come from using the wrong institution name or an old profile assumption. First confirm Mercantile is the successor, then recover the current Login ID or password, and finally trace any product that is missing after access returns.
Troubleshooting Tips
- Confirm that the old paperwork names the Alma, Michigan Firstbank group.
- Start from Mercantile Bank’s current official Online Banking Login page.
- Use Forgot Username when the Login ID is unknown.
- Use Forgot Password once and complete the Secure Access Code check.
- Stop after a lockout instead of using a fourth password attempt.
- Test MercBank Online and the official mobile app one time each.
- Record the former bank name, product, error, time, and last successful step.
- Check transaction history before repeating an interrupted payment or transfer.
A successful login with a missing account is a product-linking problem, not a password problem. A rejected password or unknown Login ID is an access problem. Keeping those separate helps Mercantile route the case correctly and avoids duplicate enrollment.
Security Tips
- Open Mercantile Bank yourself rather than following an unexpected banking link.
- Never share a Login ID, password, Secure Access Code, PIN, or full account number.
- Mercantile says its employees do not make unsolicited calls or emails asking for Online Banking credentials or account information.
- Approve a device or security code only for a login or transaction that you started.
- Use biometric access only on your own secured phone after a normal app login.
- Call the bank immediately for an unknown transaction, lost card, or stolen credentials.
- Do not use ordinary email for urgent fraud reports or confidential information.
- Review recent and pending activity after any unexpected login or code event.
Mercantile’s service agreement says telephone contact is the fastest route when a Login ID or password may be lost or stolen. The bank also says it will not contact customers unexpectedly to request those credentials. End that kind of call or message and contact Mercantile yourself.
