A wire transfer is an electronic payment that moves money directly from one bank account to another, either within the United States or across borders. You authorize your bank to push a specific amount to the recipient’s account, and the recipient’s bank receives the funds with finality once the transaction settles. Domestic wires sent through the Federal Reserve’s system are irrevocable the moment they process, which is why wires are the standard payment method for real estate closings, large business transactions, and other time-sensitive payments, and also why they are a favored tool for fraud.
How a Wire Transfer Works
Domestic wires travel through the Fedwire Funds Service, a real-time gross settlement system operated by the Federal Reserve Banks. Each transfer settles individually and immediately in central bank money, so the receiving bank gets the funds with finality the moment the payment processes. Fedwire moves trillions of dollars in value every business day.1Federal Reserve Board. Fedwire Funds Services
International wires work differently. Cross-border payments usually travel through the SWIFT network, a global messaging cooperative connecting thousands of financial institutions.2Swift. Payments SWIFT itself does not move money. It transmits secure, standardized instructions between banks, and the actual settlement happens through correspondent banking relationships where intermediary banks hold accounts with each other and adjust balances on their books. Through SWIFT’s global payments innovation (gpi) service, close to 60% of international payments now reach the recipient within 30 minutes, and nearly all arrive within 24 hours.3Swift. Swift GPI
Domestic wire transfers are governed by Uniform Commercial Code Article 4A, which most states have adopted. Article 4A defines the rights and obligations of every bank in the chain. Once a bank accepts a payment order, it is legally bound to execute it as instructed, and a bank that fails to carry out the order properly can be liable for interest losses on the delayed funds.4Legal Information Institute. UCC Article 4A – Funds Transfer
Wire Transfers Compared to ACH Transfers
People often mix up wire transfers with ACH (Automated Clearing House) transfers. Both move money electronically between bank accounts, but the differences matter.
- Wire transfers settle the same business day for domestic transactions. ACH transfers batch-process and take one to three business days, though same-day ACH is becoming more common.
- Wires carry per-transaction fees of roughly $25 to $50 depending on the destination. ACH transfers are low-cost or free for consumers.
- Wires are effectively final once the receiving bank accepts the payment. ACH transfers can be reversed in limited situations involving errors or fraud.
For routine payments like payroll, rent, or utility bills, ACH is cheaper and more flexible. Wire transfers earn their fees when you need guaranteed same-day delivery or when the recipient will not release something valuable, like keys to a house, until the funds are irrevocable.
What You Need to Send a Wire Transfer
Getting every detail right is the single most important step. One wrong digit in a routing or account number can send your money to the wrong person or leave it stuck in a holding account for weeks. Before you start, gather the following:
- The recipient’s full legal name and address, matching the name on their bank account exactly. Banks collect this to meet federal recordkeeping requirements on all wire transfers of $3,000 or more.5Federal Deposit Insurance Corporation. Section 8.1 Bank Secrecy Act, Anti-Money Laundering, and Office of Foreign Assets Control
- The receiving bank’s name and routing code. For domestic transfers, that is a nine-digit ABA routing number. For international transfers, you need a SWIFT code (also called a Business Identifier Code or BIC), an 8- to 11-character alphanumeric identifier.6American Bankers Association. ABA Routing Number7U.S. Bank. U.S. Bank Routing Number
- The recipient’s account number. For international wires to countries that use the IBAN system, you will need the recipient’s International Bank Account Number, which bundles the country code, bank code, branch code, and account number into one standardized string.8HSBC International Services Bank. What is an IBAN?
- The transfer amount and currency. For international wires, confirm whether you are sending in U.S. dollars or a foreign currency, since this affects the exchange rate and the final amount the recipient receives.
Some international transfers also require the receiving bank’s physical branch address when funds must route through intermediary banks. Your bank will provide an authorization form, either online or at a branch, with fields for each of these details. Double-check every number before you submit. Errors here are the most common cause of delayed or misdirected wires.
Sending the Transfer
Most banks let you initiate a wire transfer online, through a mobile app, by phone, or at a branch. The online process is straightforward: log in, go to the payments or transfers section, select wire transfer, enter the recipient’s details, specify the amount, and review everything carefully before confirming. Online submissions require multi-factor authentication, so you will verify your identity with something beyond your password, such as a code sent to your phone or generated by a security token. Branch transfers involve signing a physical authorization form, and the teller enters the details on your behalf. Either way, you will receive a confirmation number or receipt once the bank accepts your payment order. Keep this document. It is your proof you authorized the transfer and the starting point for any dispute.
After you confirm, the bank verifies that your account holds enough cleared funds to cover the transfer and the fees, then transmits the payment message through Fedwire or SWIFT for settlement. At that point, the transaction has left your hands. The Fedwire system operates from 9:00 PM ET the prior evening through 7:00 PM ET, Monday through Friday, excluding Federal Reserve holidays.9Federal Reserve Board. Expansion of Fedwire Funds Service and National Settlement Individual banks set their own earlier cutoff times for same-day processing, so check with your bank if timing is tight.
If you need to follow up on a delayed domestic wire, ask your bank for the Input Message Accountability Data (IMAD) and Output Message Accountability Data (OMAD) numbers Fedwire generates when the transfer is sent. These let your bank trace the payment through the Federal Reserve system.10Federal Reserve Financial Services. Fedwire Funds Service For international transfers, the equivalent is a SWIFT reference number.
Fees and Timing
Wire transfer fees vary by bank, direction, and destination. At most major U.S. banks:
- Outgoing domestic wire: $25 to $35, with some banks charging up to $40.
- Incoming domestic wire: $0 to $20, depending on the bank and account type. Some premium accounts waive this fee.
- Outgoing international wire: $25 to $50, with online submissions often cheaper than branch. On top of the flat fee, banks may apply a currency conversion markup when the recipient’s country uses a different currency, so the recipient could receive less than the full amount you sent.
- Incoming international wire: up to $25 at most institutions.
Some banks reduce or waive wire fees for customers with premium accounts or high deposit balances. Credit unions sometimes charge less than large commercial banks, which is worth comparing if you send wires frequently.
Domestic wires sent before your bank’s daily cutoff typically arrive the same business day, and many arrive within hours. International transfers have historically taken one to five business days because funds pass through intermediary banks and may undergo additional compliance screening. That timeline has improved significantly, with SWIFT reporting that close to 60% of cross-border payments through its gpi network now reach the recipient within 30 minutes.3Swift. Swift GPI Delays are still possible if the transfer must clear additional security reviews, if intermediary banks are in different time zones, or if you initiate during a bank holiday in either country.
Canceling or Reversing a Wire Transfer
This is where wire transfers get unforgiving. Under UCC Article 4A, you can cancel a domestic wire only if your bank receives the cancellation request before it accepts the payment order. Once the bank has accepted and processed the transfer, cancellation requires the receiving bank’s agreement, and the receiving bank is not obligated to agree. Even when both banks cooperate, cancellation after acceptance is only effective in narrow situations: duplicate payments, payments to the wrong beneficiary, or payments in the wrong amount.11Legal Information Institute. UCC 4A-211 – Cancellation and Amendment of Payment Order
If a wire transfer was unauthorized, your bank must refund the full payment plus interest from the date it debited your account through the date of the refund. The catch: you must discover the unauthorized transfer and notify your bank within a reasonable time, no longer than 90 days after the bank notified you of the transaction. Miss that window and you lose the right to interest on the refund.12Legal Information Institute. UCC 4A-204 – Refund of Payment and Duty of Customer to Report with Respect to Unauthorized Payment Order
Consumer Remittances to People Abroad
International wire transfers sent by consumers get better cancellation rights under federal Regulation E. If you send money to a person in another country, you have 30 minutes after making payment to cancel, as long as the recipient has not already picked up or received the funds. The provider must refund the full amount, including fees and applicable taxes, within three business days of your cancellation request.13eCFR. 12 CFR 1005.34 – Procedures for Cancellation and Refund of Remittance Transfers This rule applies to remittance transfers over $15 sent to recipients in foreign countries.14Consumer Financial Protection Bureau. 12 CFR 1005.30 – Remittance Transfer Definitions Regulation E also requires the provider to disclose the exchange rate before you pay and gives you error resolution rights for up to 180 days after the transfer.15eCFR. 12 CFR Part 1005 – Electronic Fund Transfers (Regulation E) These rights do not extend to domestic wires or to business-to-business international payments.
Avoiding Wire Transfer Scams
Because wire transfers are fast and essentially irreversible, they are a preferred tool for fraud. The FBI reported $2.77 billion in losses from business email compromise schemes alone in 2024.16Federal Bureau of Investigation. 2024 IC3 Annual Report These scams trick you into wiring money to a criminal’s account while you believe you are paying someone legitimate.
The most common scenarios follow a predictable pattern. A hacker compromises the email account of someone you trust, such as a vendor, a real estate agent, or a company executive, and then sends you new wiring instructions from that account. The email looks genuine because it comes from a real address. In real estate transactions, a scammer might impersonate a title company and send you updated wiring instructions for your down payment days before closing. By the time anyone notices the funds went to the wrong account, the money is gone.17Federal Bureau of Investigation. Business Email Compromise
Protecting yourself comes down to one habit: verify wiring instructions by phone before you send anything. Call the recipient at a number you already have on file or look up independently. Never use a phone number from the same email that contains the wiring instructions. Be especially cautious if someone pressures you to wire funds urgently or if the payment instructions changed at the last minute. If you do send a wire and suspect fraud, contact your bank immediately and ask it to initiate a recall with the receiving institution. Speed matters, and the odds of recovery drop fast once funds leave the receiving account.
