Your U.S. bank routing number is not what moves money across a border. For an international transfer, the primary identifier is your bank’s SWIFT/BIC code, and depending on the destination country you may also need an IBAN or a national code like Mexico’s CLABE. A routing number for an international transfer only comes into play in a supporting role, mainly when funds arrive in the United States and need to settle through the domestic system.
What Replaces the Routing Number Across Borders
Banks worldwide identify each other through the SWIFT network, which assigns every participating institution a Bank Identifier Code. A BIC is either eight or eleven characters: the first eight identify the bank and its country, and an optional three-character suffix points to a specific branch or department.1Swift. Business Identifier Code (BIC) When you send money abroad, the recipient’s SWIFT/BIC is the piece of routing information that does the job your domestic routing number does at home.
Roughly 80 countries also use an International Bank Account Number. An IBAN bundles a country code, check digits, and the recipient’s bank and account details into a single string. Sending to most of Europe, the Middle East, or parts of Africa and South America almost always requires an IBAN alongside the SWIFT code.
Some countries layer their own national codes on top. Mexico requires an 18-digit CLABE for incoming international wires. The United Kingdom uses a six-digit sort code alongside the IBAN. India, China, the United Arab Emirates, and several others require a purpose-of-payment code stating why you are sending the funds. Skip a required code and the transfer will stall or bounce, usually with a fee attached.
When Your Routing Number Still Matters
If someone abroad is sending money to your U.S. account, your routing number does have a role, just not the leading one. The sender’s bank routes the payment through SWIFT using your bank’s BIC. Once the funds enter the U.S. banking system, they settle through either the Fedwire Funds Service or the Clearing House Interbank Payments System (CHIPS). At that domestic stage, your bank’s routing number helps direct the money to the right institution.
That’s why some banks, when they publish their international wire instructions, list their Fedwire routing number prefixed with “//FW” inside the SWIFT message format. The tag tells the network to settle the payment through Fedwire rather than CHIPS.2Federal Reserve Bank of New York. Fedwire Funds Service International Wires Webinar If your bank includes the routing number in its wire instructions, give it to the sender. If it doesn’t, the SWIFT code alone is enough to get the money across the border.
What to Give a Sender When You’re Receiving Money From Abroad
Ask your bank for its full international wire instructions and pass those to the sender rather than improvising with just your account number and routing number. The critical field is the SWIFT/BIC code, which pulls the payment into the U.S. system. Your account number identifies you within the bank.
Provide your full legal name exactly as it appears on your account. A mismatch between the name on the wire and the name on the account can trigger a compliance hold that delays crediting. Include your bank’s branch address as well, since the sender’s bank needs it to satisfy recordkeeping rules on its side.
Expect an incoming wire fee, generally in the range of $15 to $25. If the payment passes through one or more intermediary banks along the way, each may deduct its own processing charge from the amount, so the deposit that lands in your account can be slightly smaller than what the sender originally paid. There is no reliable way to predict intermediary deductions in advance, because the routing path can vary from one transfer to the next.
What You Need Before Sending an International Wire
One wrong detail can strand your money in a correspondent bank’s holding account for weeks. Gather everything before you start.
You need the recipient’s full legal name as it appears on their bank account, plus their physical address. This is not optional. Federal anti-money laundering rules under the Bank Secrecy Act require banks to collect and retain the name and address of both sender and beneficiary for any transfer of $3,000 or more.3FFIEC BSA/AML Manual. Assessing Compliance with BSA Regulatory Requirements – Funds Transfers Recordkeeping You also need the recipient’s account number (or IBAN, if their country uses one), their bank’s SWIFT/BIC code, and the recipient bank’s name and branch address.
For some transfers, your bank will also ask for an intermediary bank’s SWIFT code. This happens when your bank has no direct relationship with the recipient’s bank and must route the payment through a third institution. In SWIFT message formatting, intermediary information sits in a dedicated field, and omitting it when required will cause the transfer to fail or be delayed.4J.P. Morgan. 2026 Global Wires Payments Formatting Requirements Guide Ask the recipient for their bank’s complete international wire instructions, which typically spell out intermediary details when they are needed.
Banks also screen every international wire against the sanctions lists maintained by the Treasury Department’s Office of Foreign Assets Control. Transfers involving sanctioned individuals, entities, or countries can be blocked entirely.5Office of Foreign Assets Control. Assessing OFAC Name Matches As of mid-2025, comprehensive U.S. sanctions prohibit or severely restrict transfers to Cuba, Iran, North Korea, and certain regions of Ukraine. An OFAC match freezes the funds until the bank resolves the flag.
Before you pay, your bank must give you a pre-payment disclosure showing the transfer amount, all fees and taxes, the exchange rate it will apply, any third-party fees it knows about, and the total the recipient will receive in the destination currency.6eCFR. 12 CFR Part 1005 Subpart B – Requirements for Remittance Transfers Read it before you confirm. Most international wires arrive within one to three business days on straightforward routes.7J.P. Morgan. How Wire Transfers Work and When to Use Them Transfers involving multiple intermediary banks, uncommon currencies, or countries with stricter regulatory checks can stretch to five days or longer.
The Costs That Add Up Beyond the Wire Fee
Outgoing international wire fees at major U.S. banks generally run between $25 and $50, with digital transfers usually costing less than branch-initiated ones.8Wells Fargo. Wire Transfers That flat fee is often the smallest cost. The bigger hit is the exchange rate. Banks do not convert at the mid-market rate you see on Google or a financial news site; they add a markup, and that spread can be a meaningful percentage of the total, especially on larger transfers. The pre-payment disclosure shows the exact rate your bank plans to use, so compare it to the mid-market rate before confirming.
Intermediary bank fees add another layer. Each middleman along the routing path can shave off anywhere from a few dollars up to roughly $50. The disclosure must flag known third-party fees, but some intermediary deductions are unpredictable and only show up as a smaller-than-expected deposit on the other end.
A practical example: you send $5,000 to a relative in Europe. Your bank charges a $35 outgoing wire fee. It converts dollars to euros at a rate about 2% worse than mid-market, roughly another $100 in effective markup. An intermediary bank along the way deducts $15. Your relative receives the equivalent of about $4,850 rather than the $5,000 you intended. Understanding this math before you send helps you adjust the amount or shop for a better rate.
Your Right to Cancel and to Dispute Errors
Federal law gives you a 30-minute window to cancel an international remittance transfer after you make payment, provided the recipient has not already received the funds. Cancel within that window and the provider must refund the full amount, including fees and applicable taxes, within three business days at no additional cost.9eCFR. 12 CFR 1005.34 – Procedures for Cancellation and Refund of Remittance Transfers To cancel, contact your bank and provide your name, contact information, and enough detail to identify the specific transfer.
Beyond cancellation, the Electronic Fund Transfer Act requires your bank to provide error resolution procedures and investigate disputes about electronic transfers.10eCFR. 12 CFR Part 1005 – Electronic Fund Transfers (Regulation E) If the amount delivered does not match what the pre-payment disclosure promised, or if the funds never arrive, you can file an error claim and the bank must investigate. Keep your confirmation receipt and pre-payment disclosure as documentation.
