Chemical Bank Routing Numbers in Michigan

Chemical Bank has 20 routing numbers registered in Michigan. When setting up direct deposit, bill pay, or wire transfers, make sure to use the routing number assigned to your specific branch or account — using the wrong one can delay or reject your transaction.

Your routing number appears on the bottom-left of any Chemical Bank check, in the Chemical Bank mobile app under account details, or by calling Chemical Bank at 989-633-5106. For ACH transfers like direct deposits and bill payments, use your state-specific routing number. For domestic wire transfers, Chemical Bank may use a different number — always confirm with the bank before sending a wire.

The reason Chemical Bank has multiple routing numbers in Michigan is typically due to historical mergers and acquisitions. When banks merge, the acquired institution's routing numbers are often preserved so existing customers don't need to update their direct deposits, autopayments, and vendor relationships. Each routing number is tied to a specific Federal Reserve processing center.

All Chemical Bank routing numbers in Michigan can be used for ACH transactions, direct deposits, and electronic payments. They are processed through the Federal Reserve and are verified using the standard ABA checksum algorithm.
