What Is a Wire Transfer Routing Number and How to Find It

A wire transfer routing number is the nine-digit code that tells the Federal Reserve’s Fedwire system which bank or credit union should receive your money. It looks like the routing number printed on your checks, but at many banks it isn’t the same number. Use the wrong one and the transfer can be rejected or, worse, sent to a different institution entirely.

What the Number Actually Does

Every bank that participates in Fedwire is assigned at least one nine-digit routing number under the American Bankers Association’s numbering system.¹ When you send a wire, the number functions as an electronic address. It tells the sending bank which institution to hand the funds to.

Federal Reserve Regulation J governs how those transfers move. Under 12 CFR Part 210, if a payment order contains a routing number that points to a different bank than the one named in the order, the Federal Reserve can rely on the number rather than the name.² One wrong digit can route your money to the wrong institution, and the Fed has no duty to catch the mistake. That is why finding the correct number matters more for a wire than for almost any other kind of payment.

How to Find Your Bank’s Wire Routing Number

The fastest source is your bank’s online portal. Log in and look under account details, transfers, or a menu labeled “wire instructions.” Most banks post the full set of wire details—routing number, bank name, address, and any intermediary information—in one place.

If the portal doesn’t show it, check your bank’s public website. Search the help center or FAQ for “wire transfer instructions” or “Fedwire.” Look specifically for language that says “wire routing number” or “Fedwire transit number” rather than just “routing number.”

For independent verification, the Federal Reserve’s E-Payments Routing Directory lets you search any bank’s routing number by name, location, or number.³ It’s free, and it confirms whether a number is active and which systems it participates in—Fedwire, FedACH, or both. If you’re still unsure, call your bank. Ask specifically whether the number works for incoming wires, since some banks route incoming and outgoing wires differently.

Why the Number on Your Check May Not Work

The routing number printed at the bottom left of a paper check is typically assigned to ACH and check processing, not to Fedwire.¹ Many large banks maintain a separate routing number for each payment system. Sending a wire with the check number can result in a rejection by the receiving bank, and the funds can sit in transit for several business days while the sending bank waits for the return. You may also lose the outgoing wire fee. Always look for a number labeled for wires, not the one on your checks.

Wire Routing Numbers vs. ACH Routing Numbers

Wire transfers and ACH transfers run on separate infrastructure. The Fedwire Funds Service settles each transfer individually and in real time; once processed, the payment is final and irrevocable.⁴ ACH works in batches, and settlement takes up to a business day or two.⁵ Because the systems are separate, many banks assign each its own routing number. Using one where the other is required generally triggers a rejection. Some banks do use a single number for both. If your bank’s website lists only one, call and confirm before you send.

Other Information You Need to Send a Wire

A routing number alone isn’t enough. For a domestic wire, you’ll typically need:

The recipient’s full legal name as it appears on the receiving account, not a nickname or business alias.
The recipient’s account number.
The recipient’s bank name and address; some banks require the branch address, not just the headquarters.
A brief purpose for the wire, which some compliance departments require before processing.

When You Need “For Further Credit” Instructions

Some transfers, particularly those going to brokerage accounts or smaller credit unions, require a “For Further Credit To” (FFC) instruction. This applies when the recipient’s institution takes all incoming wires into a single master account and then routes the money internally. You enter the master account’s routing and account information in the standard fields, and add an FFC line with the final recipient’s name and individual account number. The recipient’s institution will tell you if this is needed and what to put in the FFC field.

International Transfers

Domestic routing numbers don’t work for international wires. Banks route those payments over the SWIFT network using a Business Identifier Code (BIC), an 8- or 11-character code that identifies the bank, the country, and sometimes the branch.⁶ Many countries also require an International Bank Account Number (IBAN), and some use their own local identifier: Canada has a transit code, India has an IFSC code, Mexico requires a CLABE. Ask your recipient for the exact set of details their bank needs, and check every character. A single wrong digit can route funds to the wrong institution or delay the transfer by days.

If You Get the Number Wrong

Wires are fast and final. Once a Fedwire payment is processed, it’s immediate and irrevocable.⁴ Wire transfers are also generally excluded from the consumer protections in Regulation E, which specifically carves out transfers through Fedwire or similar wire systems.⁷ You don’t get the same error-resolution rights or liability limits that apply to debit card or ACH payments.

If you catch a mistake, contact your bank right away. Recall requests are rarely successful because they require the receiving bank and the recipient to cooperate, but the sooner you call, the better your chances.

Watch Out for Fraudulent Routing Numbers

The most common wire fraud scheme targeting routing numbers is business email compromise (BEC). A criminal impersonates a vendor, title company, or executive by email and sends fraudulent wire instructions with a routing number that leads to the scammer’s account. The messages often look almost identical to legitimate correspondence, with only slight variations in the sender’s address.⁸ A frequent scenario: a homebuyer receives an email that appears to come from the title company with “updated” wire instructions for a down payment, and the routing number goes to a criminal.

A few habits keep you out of this trap:

If wire instructions arrive or change by email, verify them by calling the recipient at a phone number you already have on file, not one provided in the email.⁸
Confirm the routing number against your bank’s own website or the Federal Reserve’s E-Payments Routing Directory before you send.³
If you suspect fraud after sending, call your bank immediately. Minutes matter.
