EFT is a direct transfer from one bank account to another, with no physical check or card involved
EFT stands for Electronic Funds Transfer. It is a way to move money from one bank account to another using computers and banking networks instead of paper checks or cash. When you receive a refund, paycheck, or bill payment via EFT, the money goes straight into your account—no envelope, no waiting for a check to arrive in the mail, no trip to the bank to deposit it.
EFT is the umbrella term for several types of electronic transfers. ACH transfers, wire transfers, and direct deposits all fall under the EFT category. For refunds and dispute resolutions, you will most often encounter ACH transfers, which are slower but cheaper than wires and work through the automated clearing house network that connects U.S. banks.
The key difference between EFT and other payment methods is speed and cost. A check takes days to arrive and days more to clear. An EFT takes one to three business days for the money to land in your account, and the sender pays little to nothing to send it. That is why refund programs, government agencies, and dispute resolution bodies prefer EFT—it is faster than mail and cheaper than wire transfers.
Key Takeaways
- EFT is any electronic transfer of money between bank accounts, including ACH transfers, direct deposits, and wire transfers.
- For refunds and dispute resolutions, ACH transfers are the most common type of EFT, taking one to three business days to arrive.
- You need to provide your bank account number and routing number to receive an EFT, and the money goes directly into your account with no action required on your part.
- EFT is safer than receiving a check in the mail because there is no physical document to lose, intercept, or forge.
- If an EFT does not arrive within the stated timeframe, your bank can trace it and the sender can confirm whether it was actually sent.
How an EFT actually moves through the banking system
When a refund or payment is sent via EFT, the sender's bank pulls the money from their account and sends it through the ACH network—a system that processes millions of transactions daily. The ACH network is not a single company; it is a set of rules and infrastructure that all U.S. banks connect to. Your bank receives the transaction information and deposits the money into your account.
The whole process takes time because the ACH network does not work in real time. Transactions are bundled together and processed in batches, usually once or twice per business day. That is why an EFT sent on a Monday might not show up until Wednesday or Thursday—the timing depends on when the sender initiated the transfer and when your bank processes incoming deposits.
Wire transfers, by contrast, move faster (often same-day) but cost more and are usually reserved for large amounts or urgent situations. For most refunds under a few thousand dollars, ACH is the standard because it is reliable and inexpensive.
What information you need to provide to receive an EFT
To receive an EFT refund or payment, you will need to give the sender your bank account number and your bank's routing number. Some programs also ask for your account type (checking or savings) and the name on the account. Do not provide your debit card number, PIN, or online banking password—those are never needed for an incoming transfer.
Your routing number is a nine-digit code that identifies your specific bank or credit union. You can find it on the bottom left of any check you have, or by calling your bank or visiting their website. Your account number is usually on the bottom of your checks as well, or you can log into your online banking to find it.
Once you provide this information, you do not need to do anything else. The money will arrive automatically. You will not receive a code to enter, a link to click, or a form to sign. If someone asks you to do any of those things to receive a refund, that is a sign of a scam.
Why refund programs and dispute resolution use EFT instead of checks
Refund programs, credit card companies, and government agencies have moved to EFT because it is faster, cheaper, and easier to track than checks. A check can be lost in the mail, stolen, or forged. An EFT leaves a digital record that both the sender and your bank can see, making it much harder to commit fraud.
For the sender, EFT is also more efficient. Processing thousands of checks costs money in printing, postage, and staff time. EFT costs almost nothing once the system is set up. That savings gets passed along in the form of faster refunds—many programs can send an EFT within days of approving your claim, whereas checks might take a week or more just to print and mail.
From your perspective, EFT means you do not have to wait for mail delivery, and you do not have to go to the bank to deposit the check. The money is straightforward there when it arrives.
What to do if your EFT refund does not arrive on time
If you were told your refund would arrive via EFT within a certain number of days and it has not shown up, start by checking your account carefully. Look at your recent transactions to see if the money arrived under a name you did not recognize. Some refunds show up with the sender's business name rather than a description you would expect.
If you genuinely do not see the money, contact the organization that sent the refund and ask for confirmation that the EFT was actually initiated. Ask them for the date it was sent, the amount, and the last four digits of the account it was sent to. Write down their response.
Then contact your bank and tell them you are expecting an incoming EFT transfer. Provide the information the sender gave you. Your bank can search their incoming transactions and either locate the transfer or confirm it never arrived. If it arrived but was sent to the wrong account, your bank can sometimes recover it. If it was never sent, the sender needs to initiate a new transfer.
This process usually takes a few business days. Do not wait more than five business days after the promised arrival date before contacting your bank—the longer you wait, the harder it becomes to trace.
EFT versus other payment methods for refunds
| Payment Method | Speed | Cost to Sender | Traceability | Risk to You |
|---|---|---|---|---|
| EFT (ACH) | 1–3 business days | Minimal | High—digital record | Low—money goes to your account |
| Wire Transfer | Same day to 1 day | $15–$50 | High—digital record | Low—but harder to reverse if sent to wrong account |
| Check | 5–10 business days | $1–$3 | Medium—can be lost or forged | Medium—can be lost, stolen, or delayed |
| Prepaid Card | 1–3 business days | $2–$5 | Medium—card number tracked | Medium—card can be lost or compromised |
How to protect yourself when providing bank information for an EFT
Providing your bank account number for an incoming transfer is generally safe—it is the information you would put on a check. However, be cautious about how you share it. Never provide your account number in response to an unsolicited email, text, or phone call, even if the person claims to be from a refund program or your bank.
Legitimate refund programs will ask for your information through a find form on their official website or through official mail. If you initiated the contact (for example, you filed a dispute and the company told you to expect a refund), then providing your account number through their official channel is safe.
Never provide your PIN, password, or the three-digit security code on the back of your debit card. Those are for outgoing transactions only. An incoming EFT requires only your account number and routing number.
If you are unsure whether a request is legitimate, hang up or close the email and contact the organization directly using a phone number or website you know is real. Do not use contact information provided in the unsolicited message.
Frequently Asked Questions
Can someone steal money from my account if they have my account number and routing number?
No. Your account number and routing number are only enough to send money to your account, not to take money out. They are the same numbers you would write on a check. To withdraw money, someone would need your PIN, online banking password, or debit card number—which you should never share.
How long does an EFT actually take if the sender says "1 to 3 business days"?
It depends on when the sender initiates the transfer and when your bank processes deposits. If sent on a Friday, it may not arrive until the following Tuesday or Wednesday because weekends do not count as business days. If sent early on a Monday, it might arrive by Wednesday. The "1 to 3 business days" is the standard window, but it can vary.
What if the EFT was sent to the wrong account?
If the sender has your wrong account number, the money will go to someone else's account. Contact the sender when ready with proof of what account number you provided. They can file a trace with the ACH network to try to recover the funds. The receiving bank can also be contacted, though they are not required to return money sent to the wrong account if the account holder refuses to cooperate.
Is EFT the same as direct deposit?
Direct deposit is a type of EFT. All direct deposits are EFTs, but not all EFTs are direct deposits. Direct deposit usually refers to recurring payments like paychecks or benefits. A one-time refund sent via EFT is still an electronic transfer, just not a direct deposit.
Can I cancel an EFT after it has been sent?
It depends on timing. If you contact the sender before the transfer has been processed by the ACH network (usually within a few hours), they may be able to cancel it. Once it has been processed and sent to your bank, cancellation becomes much harder. If the money has already arrived in your account, you would need to return it by sending money back to the sender.
