Routing Number Comerica Michigan: Quick Guide

If you bank with Comerica and opened your account in Michigan, having the correct routing number is essential for setting up direct deposit, scheduling automatic bill payments, or sending domestic wire transfers. Using the wrong number can result in delayed transactions, returned deposits, or unexpected bank fees. Here is everything you need to know about finding and using the correct routing number for Comerica in Michigan.

What Is the Routing Number for Comerica in Michigan?

For accounts opened at a Comerica Bank branch in Michigan, the standard 9-digit ABA routing transit number is:

• Comerica Michigan Routing Number: 072000096

This number applies to everyday electronic banking tasks, including:

• Direct deposits from your employer or government agencies
• Automated Clearing House (ACH) transfers and bill payments
• Paper check clearing
• Domestic incoming wire transfers

Keep in mind that banks assign routing numbers based on the geographic region where your account was initially opened. Even if you now live in another state, you must continue using the Michigan routing number if you opened your account at a Michigan location.

Direct Deposit vs. Wire Transfers: Which Number Do You Use?

Large national and regional banks sometimes designate separate numbers for electronic ACH transactions and high-value wire transfers. Comerica Bank generally uses the same primary routing transit number for Michigan accounts across standard transaction types, but it is important to understand the distinctions.

ACH and Direct Deposit

For recurring payroll deposits, tax refunds, social security payments, and automatic vendor withdrawals (such as utility bills or subscription services), use 072000096 along with your personal checking or savings account number.

Domestic Wire Transfers

If you are receiving a domestic wire transfer sent from another bank within the United States, Comerica uses the standard Michigan routing number (072000096). Be sure to instruct the sender to list the receiving institution as Comerica Bank, Detroit, MI.

International Wire Transfers (SWIFT Code)

A standard 9-digit American Bankers Association (ABA) routing number only works within the domestic U.S. banking system. If someone is sending funds to your Comerica account from an international institution, they will need Comerica's SWIFT/BIC code instead of (or in addition to) the ABA routing number.

• Comerica Bank SWIFT / BIC Code: MNBDUS33 (Detroit, MI)

When receiving foreign funds, always confirm exact wire instructions with your local branch or Comerica customer support, as international transfers may route through an intermediary bank.

How to Find Your Routing Number on Comerica Checks and Online

If you want to verify your routing number independently, there are several convenient ways to confirm it.

1. At the Bottom of a Paper Check

If you have a physical checkbook issued by Comerica, look at the line of computer-readable numbers printed across the very bottom of any blank check:

1. Routing Number (First 9 digits): The sequence between the two transit symbols on the bottom left is your Comerica routing number.
2. Account Number (Middle set of digits): The middle group of numbers represents your individual checking account number.
3. Check Number (Last set of digits): The short number matching the top-right corner of the check.

Note: Never use the numbers from a deposit slip without verifying them first, as deposit slips sometimes feature internal branch codes rather than clearing routing numbers.

2. Inside Comerica Web Banking

You can locate your specific account details digitally by logging into your account via desktop browser:

1. Log in to your Comerica Web Banking profile.
2. Select your checking or savings account from the dashboard.
3. Click on the Account Details or Account Information tab.
4. Look for the 9-digit ABA routing transit number assigned to your account.

3. Through the Comerica Mobile Banking App

If you prefer banking from your smartphone or tablet:

1. Open the Comerica Mobile app and sign in using your credentials or biometrics.
2. Tap the account you want to inspect.
3. Select Manage or Account Details to display the routing and account numbers.

Comerica Routing Numbers by State

Comerica operates in several key markets across the United States. If you established your account in a state other than Michigan, you must use that state's assigned number. Here is a quick reference table:

Common Mistakes to Avoid

Entering banking details can feel repetitive, but a simple error can tie up your funds for several business days. Watch out for these common errors:

• Confusing the Routing Number with the Account Number: The routing number identifies the financial institution, while your account number identifies your specific balance bucket. Swapping them will cause the transfer to bounce immediately.
• Using a Michigan Number for an Out-of-State Account: If you moved to Michigan from Texas and opened your account in Dallas, your account still routes through the Texas clearing center unless you explicitly moved your account portfolio to a Michigan branch.
• Omitting Leading Zeros: All ABA routing numbers contain exactly nine digits. Comerica's Michigan routing number starts with a zero (072000096). Some digital forms drop the leading zero if not formatted correctly, which triggers an invalid routing number error.

Frequently Asked Questions

What happens if I enter the wrong routing number on a payment?

If you enter an invalid or incorrect routing number, the transfer typically fails validation immediately. If the number belongs to a real bank but not Comerica, the other institution will reject the transaction once it discovers your account number does not match their internal records. The funds are typically returned to the originator within 2 to 5 business days, though your service provider may charge a returned payment fee.

Is the Comerica routing number the same for business accounts?

Yes. Commercial, business checking, and personal checking accounts opened in Michigan generally share the same routing transit number (072000096). However, complex treasury management or merchant accounts may have dedicated clearing instructions provided by your commercial relationship manager.

Can I find my routing number on a Comerica debit card?

No. The 16-digit number on your debit card is the payment card number, which routes through card networks like Visa or Mastercard. It is not an ABA routing transit number and cannot be used for electronic bank-to-bank transfers or payroll direct deposit forms.
