Yes, but the bank will verify the check before crediting your account

You can deposit a cashier's check to open a new bank account. The bank will accept it as your initial deposit, but they will not make the funds available when ready. Most banks place a hold on cashier's checks for one to five business days while they confirm the check is genuine and the issuing bank has the funds to cover it.

This hold exists even though a cashier's check is theoretically safer than a personal check — the issuing bank has already removed the money from someone's account and may provide payment. In practice, banks treat all checks the same way during the account-opening process. The hold protects the bank from fraud, which still happens with cashier's checks, and from opening accounts for people who are trying to deposit counterfeit instruments.

You will need the cashier's check itself, a government-issued ID, and proof of address (usually a utility bill or lease dated within the last 60 days). Some banks also ask for a second form of ID or a Social Security number. The specific documents vary by bank and by whether you are opening the account in person, by mail, or online.

Key Takeaways

  • Banks accept cashier's checks as opening deposits but hold the funds for one to five business days while verifying the check is real.
  • You will need a government ID, proof of address, and usually your Social Security number to open an account with any deposit method.
  • The hold begins when the bank receives and deposits the check, not when you hand it over or mail it in.
  • If the check is fraudulent or the issuing bank rejects it, the bank can reverse the deposit and close your new account.

How the hold works when you open an account

The hold is a separate process from account opening. The bank opens your account when ready — you get an account number, routing number, and debit card within hours or days depending on the bank's process. But the money from the cashier's check does not become spendable until the hold lifts.

The hold clock starts when the bank physically receives the check and enters it into their system. If you deposit it in person at a branch, the hold begins that day. If you mail it in or deposit it through a mobile app, the hold begins when the bank's back-office staff scan and process it, which is usually one to two business days after they receive the envelope.

During the hold period, the funds show in your account as "pending" or "uncollected". You can see the balance, but you cannot withdraw it, transfer it, or use it to cover checks you write. Some banks let you withdraw a small amount (often $100 to $200) before the hold lifts, but this varies by institution.

What happens if the check does not clear

If the issuing bank rejects the check — because it is counterfeit, the account it was drawn on is closed, or the signature does not match — the bank will reverse the deposit. This happens after the hold period ends, sometimes days or weeks later.

When a check is reversed, the bank removes the funds from your account. If you have already spent money from your account or transferred funds elsewhere, you will have a negative balance. The bank will charge you an overdraft fee and may close your account. You are responsible for the full amount of the bad check, not just the overdraft fee.

This is rare with cashier's checks because the issuing bank has already verified the funds. But it does happen — a cashier's check can be stolen, altered, or issued by mistake. The bank's hold protects both of you by confirming the check is real before you treat the money as yours.

Opening an account by mail with a cashier's check

If you cannot visit a branch, you can mail a cashier's check to the bank along with your account-opening paperwork. The bank will process it the same way: they will open your account, deposit the check, and place a hold on the funds.

Mailing a check adds time because the bank has to receive the envelope, open it, and scan the check before the hold begins. This usually takes three to five business days from the time you mail it. Some banks ask you to photograph the check with your phone and upload it through their website or app instead, which speeds up the process to one to two days.

If you mail the check, use a method that lets you track delivery — certified mail or a carrier with tracking. The bank will not start processing your account until they receive the envelope, and if it gets lost, you will have to stop payment on the original check and request a new one from the issuing bank.

Opening an account online with a mobile deposit

Some banks let you photograph a cashier's check with your phone and deposit it through their mobile app during account opening. This is the fastest route: the hold typically begins the same day you upload the image, and the funds clear within one to three business days.

The bank will ask you to photograph both the front and back of the check. The image has to be clear, in focus, and show the entire check. If the photo is blurry or cut off, the bank will reject it and ask you to resubmit. Once they accept the image, they will open your account and begin the hold period.

Not all banks offer mobile deposit during account opening. If yours does not, you can open the account first with a smaller deposit or no deposit, then mail or deposit the cashier's check afterward. This takes longer overall but avoids the need to visit a branch.

Timing: when you can actually use the money

The total time from deposit to available funds depends on how you deposit the check and which bank you use. Here is the typical timeline:

Deposit MethodHold BeginsHold DurationTotal Time to Available Funds
In-person at branchSame day1–5 business days1–5 business days
Mobile app photoSame day (usually)1–3 business days1–3 business days
Mailed check3–5 business days after mailing1–5 business days4–10 business days

Business days do not include weekends or federal holidays. If you deposit a check on a Friday, the hold does not begin until Monday. If the hold period is three business days and it begins on Monday, the funds are available on Thursday.

If you need the money urgently, ask the bank whether they will release a portion of the funds early. Some banks will let you withdraw $100 to $500 before the full hold lifts, especially if you are opening an account with a large deposit. This is not may provide, but it is worth asking.

Frequently Asked Questions

Do I need a minimum deposit to open an account?

This depends on the bank and the type of account. Some banks let you open a checking account with no deposit at all. Others require a minimum opening deposit, which might be $25, $100, or more. A cashier's check counts as a deposit, so if the bank requires a minimum, your cashier's check can satisfy it — but the funds will still be on hold.

What if I do not have a proof of address?

Most banks require a government-issued ID and proof of address dated within the last 60 days. If you do not have a utility bill or lease, some banks accept a bank statement, insurance document, or government letter. A few banks will open an account with just an ID if you cannot provide an address, but they may limit what you can do with the account until you add an address later.

Can I write checks before the hold lifts?

Technically yes, but it is risky. If you write a check before the cashier's check clears and it turns out to be fraudulent, your account will be overdrawn. The bank will charge you overdraft fees and may close your account. Wait until the hold lifts and the funds show as available before you write checks or make large transfers.

What if the cashier's check is lost in the mail?

Contact the bank that issued the check when ready. They can place a stop payment on it, which prevents anyone else from cashing it. Then request a replacement cashier's check. The issuing bank usually issues replacements for free, but some charge a small fee. Once you have the replacement, you can deposit it and start the hold period over.

Does the bank charge a fee to deposit a cashier's check?

Most banks do not charge a fee to deposit a check, including a cashier's check. Some banks charge a fee if you deposit a check at an ATM rather than at a branch, or if you deposit a very large number of checks in one month. Check your bank's fee schedule or ask at the branch before you deposit.
