A bank transfer slip is the form you use to authorize your bank to move money from your account to someone else’s, whether you fill it out at a teller window or through an online portal. It captures the sender and recipient details the bank needs to route funds through a wire or electronic payment network, along with the amount and your signed authorization. Get any digit wrong and the money can land in the wrong account; get a wire wrong and you may never see it again.
What the Slip Asks For
Every version of the form collects the same core information, even though the layout differs between banks and between paper and digital formats.
As the sender, you provide your full legal name and account number. For the recipient, you provide their full legal name, bank name, and account number. For domestic transfers, a nine-digit routing transit number identifies the recipient’s bank. You enter the amount, usually in both numerical and written form to reduce the chance of misreading or tampering.
Most slips include a memo or purpose field where you note what the payment is for, such as rent, a loan payment, or a gift. The date and your signature (or digital confirmation) complete the authorization. That signature is the legal record showing you approved the transaction, and it’s what the bank will point to if a dispute comes up later.
The reason the form asks for so much detail is regulatory. Under the Bank Secrecy Act, banks must collect and retain specific data about fund transfers to help detect money laundering.1FinCEN.gov. The Bank Secrecy Act For any transfer of $3,000 or more, federal rules require the bank to record the sender’s name and address, the amount, the execution date, the recipient’s financial institution, and the recipient’s name and account number when available.2eCFR. 31 CFR 1010.410 – Records To Be Made and Retained by Financial Institutions
Extra Fields for International Transfers
Sending money overseas requires information a domestic slip doesn’t ask for. Instead of a routing transit number, international transfers use a SWIFT code (also called a BIC) to identify the recipient’s bank. A SWIFT code is an 8- to 11-character alphanumeric identifier used by financial institutions worldwide.
Many countries, especially throughout Europe, the Middle East, and parts of Africa and Latin America, also require an International Bank Account Number (IBAN). An IBAN is a standardized format that includes a country code, check digits, and the recipient’s domestic account details. If the destination country requires an IBAN and you omit it, the transfer will likely be rejected or delayed. Your bank can tell you whether one is needed.
Some international transfers pass through a correspondent or intermediary bank when your bank doesn’t have a direct relationship with the recipient’s. When that’s the case, you may need to add the intermediary bank’s name and SWIFT code to the slip. Missing intermediary details is one of the more common reasons an international wire gets held up.
Identity Verification When You Submit
Before processing any transfer, the bank confirms that you are who you say you are. At a branch, that means a valid government-issued photo ID such as a driver’s license, passport, or permanent resident card. Online, the bank relies on your login credentials and may add authentication for high-value transfers, such as a one-time code sent to your phone.
This check fulfills Know Your Customer requirements under federal anti-money-laundering law, and the bank is legally required to perform it before processing.3FFIEC BSA/AML InfoBase. FFIEC BSA/AML Assessing Compliance with BSA Regulatory Requirements – Customer Identification Program The teller or system will also confirm that your account has enough cleared funds to cover the transfer plus any fees. If it doesn’t, the request is declined.
Business accounts get additional scrutiny. The person initiating the transfer typically needs to be an authorized signer, and the bank may require corporate authorization documents or a board resolution for large transactions.
Fees and Processing Times
Wire transfer fees vary by bank, direction, and whether you initiate online or at a branch. As a rough guide, outgoing domestic wires typically cost $25 to $35, with online often a few dollars cheaper than in-person. Outgoing international wires generally fall between $35 and $50. Incoming wires, both domestic and international, usually cost $0 to $15, and some banks waive them. Intermediary banks involved in international transfers may deduct their own charges from the amount that arrives.
Domestic wires sent through Fedwire, the Federal Reserve’s real-time settlement system, typically arrive the same business day if you submit before the cutoff.4Federal Reserve Board. Fedwire Funds Services International wires generally take one to five business days depending on the destination country, the number of intermediary banks, and time zone differences.
ACH transfers are a different animal and shouldn’t be confused with wires, even though both move money electronically. The Automated Clearing House network processes transfers in batches, which makes them cheaper (often free for consumers) but slower, usually settling in one to three business days.5Federal Reserve Board. Automated Clearinghouse Services Some banks offer same-day ACH for an extra fee. When you fill out a slip at a branch and ask for a wire, you’re getting Fedwire or SWIFT. When you use your bank’s online bill pay or set up an account-to-account transfer, you’re usually getting ACH.
Can You Cancel or Reverse a Transfer?
Wire transfers are extremely difficult to reverse. The FTC warns that wiring money is like sending cash, and once the recipient picks it up or it lands in their account, you usually can’t get it back.6Federal Trade Commission. What To Know Before You Wire Money That’s true regardless of amount, and it’s why scammers push wires.
If you catch a mistake before the bank processes the order, you can cancel. The window is narrow. For domestic wire transfers governed by UCC Article 4A, cancellation after the bank has accepted the payment order requires the bank’s agreement, unless the transfer was unauthorized, duplicated, sent to the wrong beneficiary, or for the wrong amount. Once accepted, the bank has no obligation to reverse it because you changed your mind.
International remittance transfers get somewhat better protection. Under the CFPB’s remittance rule, you have 30 minutes after making payment to cancel, as long as the recipient hasn’t yet picked up or received the funds, and the provider must refund the full amount within three business days.7Consumer Financial Protection Bureau. 12 CFR 1005.34 – Procedures for Cancellation and Refund of Remittance Transfers The rule covers providers like Western Union and MoneyGram, but large bank-to-bank international wires may fall outside its scope.
If you discover a fraudulent transfer, call your bank immediately. The FBI’s Internet Crime Complaint Center runs a Financial Fraud Kill Chain process that can freeze fraudulent wires, but the odds of recovery drop sharply with every hour that passes.8FBI Internet Crime Complaint Center. 2025 IC3 Annual Report
When Transfers Get Reported
Large transfers trigger mandatory government reporting. Banks must file a Currency Transaction Report for any cash transaction over $10,000 in a single business day, including multiple smaller transactions that add up past that threshold.9FinCEN. Frequently Asked Questions Regarding the FinCEN Currency Transaction Report Deliberately breaking a transfer into smaller amounts to duck the reporting requirement is called structuring and is a federal crime, even when the underlying money is entirely legitimate.
If you hold or have signature authority over financial accounts outside the United States with an aggregate value over $10,000 at any point during the year, you must file a Report of Foreign Bank and Financial Accounts (FBAR) with FinCEN.10FinCEN.gov. Report Foreign Bank and Financial Accounts Regular international transfers don’t trigger this requirement on their own, but they can indicate you have foreign accounts that do.
Banks must retain records of fund transfers for at least five years under the Bank Secrecy Act.11FFIEC BSA/AML InfoBase. FFIEC BSA/AML Appendices – Appendix P – BSA Record Retention Requirements Keep your own copies too. The IRS expects you to maintain records supporting any item on your tax return for as long as the statute of limitations remains open, generally three years, but sometimes six or more.12Internal Revenue Service. Topic No. 305, Recordkeeping A receipt showing a $15,000 gift transfer matters for gift tax reporting; keep it with your tax records.
Protecting Yourself From Wire Fraud
The most common wire fraud schemes include business email compromise (where a scammer impersonates a vendor or executive and sends fake payment instructions), romance scams, family emergency calls, and fake prize or rental listings.6Federal Trade Commission. What To Know Before You Wire Money They share a playbook: manufacture urgency, then push the victim to wire money before they have time to verify anything.
The single most effective defense is independent verification. If wire instructions arrive by email, call the sender at a number you already have on file, not one from the email itself. Business email compromise attacks often involve hacked or spoofed accounts that look identical to the real thing. An employee who wires $80,000 based on a convincing email has almost no legal recourse to recover the funds.
A few habits that reduce your exposure:
- Confirm wire instructions through a separate channel, especially if anything changed from previous transactions.
- Question urgency. Legitimate recipients rarely demand an immediate wire with no time to verify details.
- Read every digit of the account and routing numbers back to the teller, or review them character by character online. A single transposed digit can send your money to a stranger.
- Save your receipt. The transaction reference number is your only tool if you later need the bank to trace or attempt to recall the transfer.
If you realize you’ve been scammed, call your bank immediately and ask them to issue a recall, then file a complaint with the FBI’s IC3 at ic3.gov. The sooner law enforcement can send a freeze request to the receiving bank, the better the chance of recovering any portion of the funds.
