Which BMO routing number do you need?
071025661, and BMO leaves no room to argue: “The routing number for all BMO personal bank accounts is 071025661.” No state table or per-region variant to work out for a personal account — and the same number appears in BMO’s instructions for receiving a domestic wire.
| Payment | What the sender needs | Where BMO publishes it |
|---|---|---|
| Domestic wire | 071025661 | BMO’s incoming-wire instructions |
| International wire | HATRUS44 | Same page, listed as the BIC/SWIFT |
| Direct deposit or ACH | 071025661 | BMO’s one-number answer for personal accounts |
How to find your own BMO routing number
Read the bottom left of a check
The left-most nine digits are the routing number, followed by the account number and then the check number.
Or take BMO at its word
BMO states one routing number covers all personal accounts, so 071025661 is the answer for a personal deposit account.
Or ask, if the account is a business or legacy one
BMO’s US line is 1-888-340-2265, open 7 a.m. to 11 p.m. CT on weekdays and 8 a.m. to 10 p.m. at weekends.

Every routing number the Fed lists for this bank has its own page in the table below.
Why the Fed lists 140 routing numbers for one bank
The American Bankers Association assigns routing numbers to eligible institutions. The first four digits form the Federal Reserve routing symbol; for banks, the first two identify the district. The Fed uses a parallel band for thrifts and credit unions: a leading 2 in districts 1 to 9 and a leading 3 in districts 10 to 12.
| District | Leading digits | Routing numbers |
|---|---|---|
| Seventh — Chicago | 07, 27 | 109 |
| Ninth — Minneapolis | 09 | 13 |
| Twelfth — San Francisco | 12, 32 | 6 |
| Sixth — Atlanta | 06 | 4 |
| Eighth — St. Louis | 08 | 4 |
| Tenth — Kansas City | 10, 30 | 4 |
Nearly four in five sit in the Seventh District — including 071025661, which opens 0710, a routing symbol the Fed lists against Chicago. All 140 are distinct and all 140 pass the ABA check-digit test. A nine-digit candidate that fails that test is not a valid ABA routing number; passing it does not prove a number is active.

Once it lands, BMO’s disclosure gives wire transfers and direct deposits same-day availability. Its wire FAQ adds that a domestic wire is typically released and received the same day, while an international one usually takes several business days to reach the recipient.
What BMO charges to send and receive a wire
| Wire | Fee |
|---|---|
| Incoming, domestic or international | Free |
| Outgoing domestic | $30.00 |
| Outgoing international | $50.00 |
| Incoming wire BMO cannot process, $100 or more | $35.00 returned-wire fee |
BMO tells customers choosing between USD and an available foreign currency to consider “the total cost and amount available to the recipient, including exchange rates and fees”. Its FAQ also warns that wire fees and account benefits can vary by account type, so check the disclosure for your account before relying on the standard schedule above.
BMO Harris, M&I, Bank of the West: whose number is on your check?
BMO completed the acquisition of M&I on 5 July 2011 and combined M&I Bank with Harris Bank as BMO Harris Bank. The OCC identifies it as BMO Bank N.A. after 3 September 2023; the FDIC’s current record is certificate 16571.
- BMO Harris Bank is a prior name of the current institution, but the old name alone does not prove that a routing number printed beside it is still active.
- A number printed under M&I or Harris Bank predates two renamings; verify it before using it for payroll.

Frequently asked questions
What is the BMO routing number?
071025661. BMO’s own words are “The routing number for all BMO personal bank accounts is 071025661,” and the same number appears in its instructions for receiving a domestic wire. The historical FedACH-derived snapshot behind this page carries 140 numbers under the former BMO Harris name, but it does not establish that every legacy number is active today.
Is the BMO Harris routing number the same as the BMO routing number?
For the personal-account number BMO publishes now, yes: 071025661. BMO Harris Bank is a prior name of BMO Bank N.A., but that name on an old check does not by itself prove the printed routing number is still active. Confirm an old number with BMO before using it.
What is BMO’s SWIFT code?
HATRUS44. BMO lists it as the BIC/SWIFT on its own page for receiving an international wire, alongside the beneficiary bank name BMO Bank N.A. and the address 320 S. Canal Street, Chicago, IL 60606. It is not interchangeable with the routing number: a sender inside the US needs the ABA, 071025661, and a sender abroad needs the BIC/SWIFT.
Does BMO charge to receive a wire transfer?
No. BMO’s Deposit Account Disclosure, as published February 2026, lists incoming wire transfers as free. The one incoming charge to know about is the $35 wire return fee: if BMO receives a wire it cannot process and the amount is $100 or more, that fee is deducted from what gets sent back to the originating bank. Outgoing wires cost $30 domestic and $50 international.
What time is BMO’s wire cutoff?
BMO publishes two different answers, so the earlier one is the conservative deadline. Its digital banking FAQ gives 4:30 p.m. CT for domestic wires and 4 p.m. CT for international. Its contact page gives 4 p.m. CT for domestic and 3:30 p.m. CT for international. BMO says a domestic wire released the same day is typically received the same day.
Why does my BMO routing number show a Naperville, Illinois address?
The FedACH participation form calls this field the operations address; it is not necessarily the branch where an account was opened. In the historical snapshot here, 135 of 140 entries carry a spelling of 1200 E. Warrenville Road, Naperville — also the address BMO gives for its Wire Transfer Support Unit.
I was a Bank of the West customer — which routing number do I use?
Ask BMO rather than reusing an old one. BMO completed the acquisition on 1 February 2023 and converted Bank of the West customer accounts and systems in September 2023. The historical directory extract still lists 18 Bank of the West numbers separately, so it cannot identify your current number. BMO publishes 071025661 for personal accounts; its US customer line is 1-888-340-2265.
Can I cancel a BMO wire transfer after sending it?
Only within a narrow window, and only for consumer international wires. BMO says a Remittance Transfer — an international wire sent by a consumer for personal, family or household purposes — can be cancelled for a full refund within 30 minutes of payment by calling 1-855-734-2648, unless the funds have already been picked up or deposited. If something went wrong instead, BMO takes error disputes for 180 days on 1-877-696-7379.
