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 should receive your money. It’s often different from the routing number printed on your checks, and the fastest place to find the correct one is your bank’s online banking portal or its published wire instructions page. If you want to verify independently, the Federal Reserve’s E-Payments Routing Directory lets you look up any U.S. bank’s number by name or location.¹

Every bank or credit union that participates in Fedwire is assigned at least one nine-digit routing number under the American Bankers Association’s numbering system.² When you give a sending bank a routing number, you’re pointing at the specific institution that should end up with the funds. Under Federal Reserve Regulation J, if a payment order lists a routing number that points to a different bank than the one named, the Fed can rely on the number rather than the name.³ One wrong digit can send your money to the wrong institution, and the Fed has no duty to catch it.

How to Find Your Bank’s Wire Routing Number

Start with your online banking portal. Most banks list wire instructions inside the account details or transfers section, and the number shown there is the one to use. If you don’t see it, search your bank’s public website for a page labeled “wire transfer instructions” or “Fedwire transit number.” Calling customer service works too, and it’s the surest way to confirm whether the same number applies to incoming and outgoing wires.

For an independent check, the Federal Reserve’s E-Payments Routing Directory is free and shows whether a given number is active on Fedwire, FedACH, or both.¹ Use it to confirm a number someone else has given you before you send anything.

Why the Number on Your Check May Not Work

The routing number printed at the bottom left of a paper check is typically the one assigned to ACH and check processing, not Fedwire.² Many large banks maintain separate routing numbers for each payment system. Send a wire with a check routing number and the receiving bank may reject it, leaving your money in limbo for several business days while the sending bank waits for the return. Look for the number labeled specifically for wires.

Some banks do use a single routing number for both ACH and wires. If your bank’s website only shows one, call to confirm it works for Fedwire before you send.

Wire vs. ACH: Different Rails, Different Numbers

Wire transfers and ACH transfers run on different infrastructure, which is why the numbers often differ. Fedwire settles each transfer individually and in real time, and once processed the payment is final and irrevocable.⁴ ACH batches transactions and settles them in groups, with about 80 percent of ACH payments settling within one banking day.⁵ Using the wrong routing number for the rail you’ve chosen usually triggers a rejection, and you may still lose the outgoing wire fee.

What Else You Need to Send a Wire

The routing number is only part of what a sending bank asks for. For a domestic wire, you’ll typically need:

The recipient’s full legal name as it appears on the receiving account.
The recipient’s account number.
The recipient’s bank name and address; some banks want the branch address, not the headquarters.
The purpose of the wire, which some banks require for compliance.

Certain transfers, especially those going to brokerage accounts or smaller credit unions, also need a “For Further Credit To” (FFC) instruction. This applies when the receiving institution takes all incoming wires into one master account and then routes them internally. You’d enter the master account’s routing and account details in the standard fields and add the final recipient’s name and account number in the FFC field. Your recipient’s institution will tell you if FFC instructions are needed.

International Wires Use Different Codes

A U.S. ABA routing number won’t move money across borders. International transfers rely on the SWIFT network’s Business Identifier Code (BIC), an 8- or 11-character alphanumeric code that identifies the bank, the country, and, when 11 characters are used, the specific branch.⁶ Many countries also require an International Bank Account Number (IBAN). Some countries layer on their own local identifiers: Canada uses a transit code, India uses an IFSC code, and Mexico requires a CLABE number. Ask your recipient for the full list of codes their bank needs before you initiate the transfer.

What Wires Cost

Fees vary by bank, account type, and direction. As a rough guide for domestic wires, expect $20 to $35 for an outgoing transfer and $0 to $20 for an incoming one. Many credit unions and premium accounts waive incoming fees. International outgoing wires often run $35 to $50 or more, and the recipient may pay a separate incoming fee.

International wires also carry a hidden cost most senders miss: the currency exchange markup. Banks convert funds at a rate less favorable than the mid-market rate, and the markup is embedded in the quoted rate rather than shown as a separate line item. A “no fee” international wire can still cost you real money through the exchange spread.

Protect the Routing Number Against Fraud

Wire transfers carry a risk that catches people off guard: once the funds move through Fedwire, the transfer is immediate, final, and irrevocable.⁴ Regulation E, which gives you error-resolution rights and liability limits on debit card and ACH errors, specifically carves out transfers through Fedwire and similar systems.⁷ If a wire lands in the wrong account, you don’t have the same consumer protections.

The most common scheme aimed at 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 emails often look nearly identical to legitimate correspondence, with only slight variations in the sender’s address.⁸ A common version: 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 points to a criminal.

Three habits reduce the risk sharply:

Verify any changed wire instructions by phone, using a number you already have on file — not one included in the suspicious email.⁸
Confirm the routing number independently against your bank’s website or the Federal Reserve’s E-Payments Routing Directory before you send.¹
Contact your bank immediately if something feels wrong. Recall requests rarely succeed because they need the receiving party’s cooperation, but acting within minutes gives you the best chance of recovering funds.

The routing number is small, but it decides where your money goes. Confirm it from a source you control, match it to the payment rail you’re actually using, and verify any changes by phone before the wire leaves your account.
