What wire instructions are and why you need them

Wire instructions are the routing and account details a bank needs to send money to someone else's account. They tell the sending bank exactly where to direct the funds — which bank, which branch, which account, and whose name it belongs to. Without correct wire instructions, your money can end up in the wrong place or get stuck in processing.

Wire instructions are different from your own account number. Your account number is what people use to send money to you. Wire instructions are what you provide when you want to send money out. They belong to the person or business receiving the payment, not the person sending it.

You will need wire instructions when you are paying a mortgage, sending money to another country, paying a contractor, or transferring funds between your own accounts at different banks. The receiving bank or the person receiving the money will give you these instructions — you do not create them yourself.

Key Takeaways

  • Wire instructions include the receiving bank's name, routing number, account number, and the account holder's name — all provided by the person or business receiving the money.
  • You get wire instructions from the recipient, not from your own bank, and you should always confirm them directly with the recipient before sending money.
  • A routing number identifies the bank; an account number identifies the specific account within that bank.
  • Incorrect wire instructions can send your money to the wrong account, and recovering it is difficult and sometimes impossible.
  • Most banks allow you to send domestic wires online, by phone, or in person, and international wires usually require a visit to a branch or a phone call.

The pieces of wire instructions

Wire instructions typically include four core pieces of information. The receiving bank name is the full legal name of the bank where the recipient's account is held — for example, "JPMorgan Chase Bank, N.A." or "Wells Fargo Bank, National Association." This is not a nickname or shortened version; banks are particular about the exact legal name.

The routing number (also called an ABA number for domestic U.S. wires) is a nine-digit code that identifies the specific bank branch. It tells your bank which institution to send the money to. The account number is the unique identifier for the individual account at that bank — usually between 8 and 17 digits. Together, the routing number and account number pinpoint the exact account.

The account holder's name must match the name on the account exactly as it appears in the bank's records. If the account is in the name "Robert J. Martinez" and you wire it to "Bob Martinez," the receiving bank may reject it or hold it for verification. For business accounts, use the legal business name on file.

International wires require additional information: a SWIFT code (also called a BIC code) instead of or in addition to a routing number, the bank's address, and sometimes an IBAN (International Bank Account Number) depending on the country. The recipient should provide all of this.

How to get wire instructions from the recipient

Ask the person or business you are paying to send you their wire instructions. Most organizations have a standard format they use — many businesses print it on invoices, include it on their website, or email it when you ask. For a mortgage company, contractor, or service provider, a straightforward email asking "What are your wire instructions?" usually gets a quick response.

If the recipient is another individual, ask them to contact their bank and request their own wire instructions. Their bank can provide this information, often through online banking or by calling customer service. Some banks print wire instructions on statements or make them available through the mobile app.

Never guess or use information you find online. Banks with the same name can have different routing numbers in different regions. Always get the instructions directly from the recipient or from their bank, not from a search result or a third-party website.

Confirming wire instructions before you send

Before you initiate a wire, confirm the instructions with the recipient one more time. Call them, email them, or ask them to verify what they sent you. This step prevents the most common wire error: sending money to the right bank but the wrong account because a digit was transposed or misread.

Check that the account holder's name matches exactly. If you are wiring to a business account but the instructions show a personal name, or vice versa, ask for clarification. Banks will sometimes reject a wire if the account holder name does not match, or they will hold it pending verification — either way, your money is delayed.

For large amounts or international wires, consider asking the recipient to confirm the instructions in writing (email is fine). This creates a record if something goes wrong and protects both of you. If the recipient seems unsure or the instructions look incomplete, contact their bank directly using the phone number on their website — not a number the recipient gives you.

Sending a domestic wire with wire instructions

Log into your online banking portal or mobile app and look for "Send Money," "Wire Transfer," or "Payments." Most banks offer this option for domestic wires. You will enter the routing number, account number, account holder name, and the amount you want to send. Double-check each field before you submit.

Some banks require you to call or visit a branch for wires over a certain amount, or for your first wire to a new recipient. This is a security measure. Have your wire instructions ready when you call or visit, and be prepared to answer security questions to confirm your identity.

After you submit the wire, your bank will give you a confirmation number. Save this number. Domestic wires usually arrive within one business day, though same-day options exist at some banks for an additional fee. The receiving bank will post the funds to the recipient's account, and they will see your name as the sender.

Sending an international wire with wire instructions

International wires are more complex and almost always require a phone call or an in-person visit to your bank. You cannot usually send them through online banking. Call your bank's wire transfer department or visit a branch with the recipient's wire instructions in hand.

Your bank will ask for the SWIFT code, the recipient's full name and address, the receiving bank's name and address, and the amount and currency. They will also ask why you are sending the money (this is required by law for anti-money-laundering compliance). Be ready to explain — "paying a contractor," "family support," or "tuition payment" are all normal answers.

International wires take longer than domestic ones — typically three to five business days, sometimes longer depending on the countries and banks involved. Fees are higher, and the exchange rate your bank uses may differ from the mid-market rate. Ask your bank for the total cost, including fees and the exchange rate, before you authorize the wire.

What to do if a wire goes to the wrong account

If you realize you sent a wire to the wrong account, contact your bank when ready. The sooner you report it, the better your chances of recovery. Your bank can attempt to recall the wire, but success depends on whether the receiving bank has already released the funds and whether the recipient cooperates.

If the funds have been released and spent, recovery is very difficult. Your bank may be able to file a claim, but this process is slow and often unsuccessful. This is why confirming wire instructions before sending is so important — prevention is far easier than recovery.

Keep your confirmation number and all documentation related to the wire. If you need to dispute it or file a claim, your bank will ask for these details. Do not assume the wire will be reversed automatically; you must report the error and follow your bank's process.

Frequently Asked Questions

What is the difference between a routing number and an account number?

A routing number identifies the bank or branch where the account is held. An account number identifies the specific account within that bank. You need both to send a wire — the routing number tells your bank which institution to contact, and the account number tells that institution which account to deposit the money into.

Can I use someone's account number without a routing number to send a wire?

No. A routing number is required for domestic wires. Without it, your bank does not know which bank to send the money to. For international wires, you need a SWIFT code instead of or in addition to a routing number. Always get complete wire instructions from the recipient.

How long does a wire take if I send it on a Friday?

Domestic wires sent on Friday usually arrive on Monday, since banks do not process wires on weekends. International wires take longer regardless of the day — typically three to five business days. Some banks offer expedited options, but these cost more. Ask your bank for timing before you send.

Do I need wire instructions to send money to someone at the same bank as me?

Not always. If you and the recipient both have accounts at the same bank, you may be able to transfer money through online banking without wire instructions — this is called an internal transfer and is usually faster and free. Ask your bank whether you can transfer between accounts at the same institution, or whether you need to use wire instructions.

What if the wire instructions I received look incomplete or confusing?

Contact the recipient and ask them to clarify or resend the instructions. If you are still unsure, call the receiving bank directly using the phone number from their official website and confirm the account details. Do not send a wire based on incomplete or unclear instructions — the risk of sending money to the wrong place is too high.
