For an international wire, your U.S. bank’s nine-digit routing number is only half the story. Your bank uses it internally to pull money from your account, but it means nothing to a foreign bank on the receiving end. To actually deliver funds abroad, you need a different set of identifiers for the recipient’s bank, typically a SWIFT/BIC code and, in most of the world, an IBAN or a country-specific code.
What Your Routing Number Actually Does on an International Wire
The American Bankers Association (ABA) routing number is a nine-digit code assigned to U.S. financial institutions. It exists to move money through domestic systems like the Fedwire Funds Service and the Automated Clearing House (ACH) network.1American Bankers Association. ABA Routing Number Those systems only connect banks inside the United States, so the routing number cannot reach a foreign institution on its own.
When you initiate an international wire, your bank still uses your routing number internally to verify your account and authorize the outgoing debit. Foreign banks do not recognize ABA routing numbers for the purpose of receiving funds, so giving only your routing number to someone overseas will not help their bank locate an incoming payment.
Wire Routing Number vs. ACH Routing Number
Some U.S. banks assign different routing numbers for wires and for ACH transactions. ACH routing numbers handle batch-processed electronic transfers like direct deposits and bill payments; wire routing numbers support real-time, individual bank-to-bank transactions. Before you start an international wire, confirm with your bank which routing number applies. Using the wrong one can stall the transfer at the first step. The correct number is usually on your bank’s website, on your checks, or available from customer service.
What the Foreign Bank Actually Needs
The recipient’s side is where the routing gets done. Missing or incorrect data here is the most common reason international wires get delayed, returned, or sent to the wrong account.
Every international wire requires:
- Recipient’s full legal name and address, matching what their bank has on file.
- Recipient’s bank name and address.
- SWIFT/BIC code: an 8- or 11-character alphanumeric code that identifies the recipient’s bank, and with 11 characters, a specific branch.2Swift. Business Identifier Code (BIC)
- Recipient’s account number or IBAN. Many countries require an IBAN, which runs 15 to 34 characters depending on the country and includes a country code and check digits that catch some errors before the transfer is sent.3IBAN.com. IBAN Examples, Structure and Length
Most of this information appears on the recipient’s bank statement or in their online banking portal. If they don’t have it handy, they can ask their bank for “incoming international wire instructions.”
Country-Specific Codes to Watch For
Some countries need an additional code on top of the SWIFT/BIC and account number. A wrong or missing one can park your funds in a holding account while the banks sort it out.
- IBAN is required across the European Union, the United Kingdom, and dozens of other countries, including parts of North Africa, the Caribbean, and South America.
- Canada uses a five-digit transit number paired with a three-digit institution number to identify the specific branch.4Payments Canada. Directories
- Mexico requires an 18-digit CLABE, which routes funds through Mexico’s interbank system (SPEI).5Banco de Mexico. Information for SPEI Users
- Australia uses a six-digit Bank State Branch (BSB) code in XXX-XXX format.6AusPayNet. BSB Lookup
- India uses the Indian Financial System Code (IFSC) to identify the specific branch for incoming remittances.
A single wrong character in any of these codes can misroute the funds. Double-check every one before you submit.
Purpose of Payment
Many banks ask you to describe or select the reason for the transfer, such as paying for goods, tuition, family support, or taxes. Banks use this for anti-money-laundering screening, and some countries require it for incoming foreign currency. A vague answer or a blank field can trigger a manual review.
Correspondent Banks and How Fees Are Split
Not every U.S. bank has a direct relationship with every foreign institution. When yours doesn’t, one or more correspondent (intermediary) banks step in and pass the funds along through the SWIFT network. Your bank may ask for the correspondent’s SWIFT code and “For Further Credit” (FFC) instructions that tell it which final account should receive the money. Without clear FFC instructions, the intermediary may hold the funds while it waits for clarification.
Most banks also ask you to choose how intermediary fees are handled:
- OUR: you pay all transfer fees, and the recipient gets the full amount.
- SHA (shared): you pay your bank’s outgoing fee; the recipient’s bank deducts its own fees from the arriving funds.
- BEN (beneficiary): the recipient pays all fees. Every intermediary deducts its charge along the way.
If the recipient needs an exact amount, for instance to cover a specific invoice, choose OUR. SHA is the most common default. When a recipient reports getting less than expected, the fee-sharing choice is almost always why.
Fees, Timing, and Limits
You can start the transfer through your bank’s online portal, mobile app, or in a branch. Before you confirm, your bank must show you the exchange rate it will apply, all transfer fees (including any third-party fees), and the date the funds are expected to arrive in the foreign country.7eCFR. 12 CFR 1005.31 – Disclosures These disclosures are required under the Electronic Fund Transfer Act’s remittance transfer rules. Read them. An exchange rate markup can sometimes cost more than the flat wire fee.
Outgoing international wire fees at most U.S. banks run roughly $35 to $50, though some charge more. Many also build a markup into the exchange rate that doesn’t appear as a line item. Credit unions sometimes offer lower flat fees but may still mark up the exchange rate. The recipient’s bank may add its own incoming wire fee.
Banks set daily or per-transaction caps on consumer international wires. At some institutions the standard online limit is $50,000 per business day, while premium account tiers may have higher limits or none. To send more than the default, contact your bank; higher amounts often require an in-branch visit or extra verification.
International wires from a U.S. bank typically arrive within one to five business days, depending on the currency, the number of intermediary banks, and the processing speed of the receiving bank.8Bank of America. Send Wire Transfers in Online Banking or Our Mobile Banking App Once the wire goes out, your bank will give you a transaction reference number. You can also request a SWIFT MT103, formal proof the payment was sent that shows all transaction details, including fees.
If You Made a Mistake: Cancellation and Disputes
Federal law gives you a short window to change your mind. You can cancel an international wire and get a full refund of the transfer amount and all fees if you contact your bank within 30 minutes of making payment, as long as the recipient has not already picked up or deposited the funds.9eCFR. 12 CFR 1005.34 – Procedures for Cancellation and Refund of Remittance Transfers Your bank must process the refund within three business days of receiving your request.
If a problem surfaces later, say the money went to the wrong account, the wrong amount arrived, or the transfer never showed up, you can file an error dispute. The bank must investigate and report its findings within 90 days of your notice.10eCFR. 12 CFR 1005.33 – Procedures for Resolving Errors If it finds an error, it must tell you what remedies are available. If it finds none, it must explain in writing and, on request, give you copies of the documents it relied on.
Large-Transfer Reporting Obligations
Sending or receiving large sums abroad can trigger federal reporting requirements that fall on you, not just your bank. Your routing number isn’t the trigger here; the size and nature of the money is.
If you hold financial accounts outside the United States and their combined value exceeds $10,000 at any point during the year, you must file a Report of Foreign Bank and Financial Accounts (FBAR) with FinCEN.11FinCEN. Report Foreign Bank and Financial Accounts The requirement comes from 31 U.S.C. ยง 5314, and the report is filed electronically as FinCEN Form 114.12Office of the Law Revision Counsel. 31 USC 5314 – Records and Reports on Foreign Financial Agency Transactions The deadline is April 15, with an automatic extension to October 15.
If you receive a large gift or bequest from a foreign person, separate IRS rules apply. Gifts from a nonresident alien or a foreign estate totaling more than $100,000 in a single tax year must be reported on Form 3520. Gifts from foreign corporations or partnerships have a lower reporting threshold that is adjusted annually for inflation.13Internal Revenue Service. Large Gifts or Bequests From Foreign Persons These are reporting requirements only. They don’t create a tax on the gift itself, but the penalties for not filing can be significant.
