What a mobile bank account is and how to start one

A mobile bank account is a checking or savings account you open and manage entirely through a smartphone app, without visiting a physical branch. You read the bank's app, provide your personal information, verify your identity, and fund the account — all from your phone. Most mobile banks are real banks with FDIC insurance, meaning your money is protected up to $250,000 if the bank fails.

The main difference from a traditional bank account is that there is no physical location to walk into. Everything happens through the app: depositing checks by taking a photo, transferring money, paying bills, and contacting customer service. Some mobile banks are entirely online-only; others are the mobile apps of banks that also have branches.

Mobile accounts typically have lower fees than traditional banks because they have fewer physical locations to maintain. Many charge no monthly fee, no minimum balance, and no overdraft fees. The tradeoff is that you cannot deposit cash directly — you deposit checks by photograph or transfer money from another account.

  • The entire process from read to first deposit usually takes 10 to 20 minutes, though identity verification can add a day or two.
  • You cannot deposit cash directly at a mobile bank, but you can deposit checks by photograph or transfer money from another account.

What documents and information you will need

Before you start, gather these items: a government-issued photo ID (driver's license, passport, or state ID), your Social Security number, and proof of your current address. The address proof can be a recent utility bill, lease, mortgage statement, or bank statement — something dated within the last 60 days that shows your name and address.

You will also need a smartphone with internet access and, for most banks, a valid email address. Some mobile banks ask for a phone number as well. If you plan to deposit checks by photograph, you will need a smartphone camera that can take clear photos.

Have your information ready before you start the app. The process moves faster if you do not have to stop and search for your Social Security number or dig through papers for an address document.

The step-by-step process to open the account

Step 1: read the app and start the account setup. Go to your phone's app store (Apple App Store or Google Play), search for the bank's name, and read the official app. Open it and look for a button that says "Open an account" or "Sign up." Do not use a link from an email or text message — go directly to the app store to make sure you have the real app.

Step 2: Enter your personal information. The app will ask for your full name, date of birth, Social Security number, email address, and phone number. Type carefully — mistakes here can slow down the verification step. You will also enter your current address.

Step 3: Verify your identity. Most banks use one of two methods. The first is a photo: you take a picture of your ID using your phone camera, and the bank's system reads it automatically. The second is a video call: a bank employee watches you hold up your ID and answer a few questions to confirm you are who you say you are. This step usually takes 5 to 10 minutes, though some banks complete it when ready.

Step 4: Choose your account type. Most mobile banks offer a checking account, a savings account, or both. A checking account is for money you use regularly; a savings account earns a small amount of interest. If you are new to banking, a checking account is the right choice for now.

Step 5: Set up a PIN and security. Create a four- to six-digit PIN that you will use to log into the app. The bank will also ask you to set up a way to receive security codes — usually a text message to your phone. This protects your account if someone else gets your password.

Step 6: Fund the account. The bank will ask how you want to put money in. The most common way is to transfer money from another bank account you already have. You provide the account number and routing number from that account, and the bank transfers the money — usually within one to three business days. Some banks let you start with a very small transfer (like $1) to test that the connection works, then transfer more later.

How long the process takes and what happens next

From read to having a working account usually takes 10 to 20 minutes if your identity verifies when ready. If the bank needs to do a video call with you, add another 5 to 10 minutes. If the bank cannot verify you automatically, they may ask you to mail in a copy of your ID, which adds several days.

Once your account is open, you can use it when ready to receive money. If you set up a transfer from another account, that money will arrive within one to three business days. You can start using your debit card (if the bank mails one) as soon as it arrives, which is usually within 5 to 10 business days.

Some mobile banks offer a temporary digital card number you can use online or in stores right away, before the physical card arrives. Check your app to see if this option is available.

How to deposit checks and cash with a mobile bank

Mobile banks do not accept cash deposits directly. If you have cash, you will need to deposit it at an ATM that accepts cash (many do not), transfer it to someone else's account, or use a service like a check-cashing store. Some mobile banks partner with ATM networks so you can withdraw cash for free, but depositing cash is not an option.

To deposit a check, open your app and look for a "Mobile deposit" or "Deposit check" button. Take a photo of the front and back of the check using your phone camera. The app will read the check number and amount automatically. Review the information, confirm it is correct, and submit. The check usually clears within one to three business days.

After you deposit a check, you must either destroy it or write "VOID" across it in large letters. Do not deposit the same check twice — banks track this and will reverse the deposit and charge you a fee.

Fees and features to compare between mobile banks

Most mobile banks charge no monthly fee, no minimum balance, and no overdraft fees. However, they differ in other ways. Some pay interest on checking accounts (very small amounts, usually less than 1% per year), while others do not. Some offer free ATM withdrawals at thousands of locations; others charge a small fee. Some have customer service available 24 hours a day by phone or chat; others only offer email support during business hours.

Before you open an account, spend 10 minutes reading the bank's fee schedule and terms. Look for the monthly fee (should be zero), overdraft fees (should be zero or not mentioned), ATM fees, and what happens if your account goes negative. Also check whether the bank is FDIC-insured — this information is usually on the main page of the app or website.

If you plan to deposit checks regularly, make sure the bank's mobile deposit feature works with your phone's camera. If you need to withdraw cash often, check whether the bank has a large ATM network in your area.

What to do if your identity does not verify automatically

If the bank cannot verify you using your ID photo or video call, they will ask you to mail in a copy of your ID and sometimes a proof of address. This adds 5 to 10 business days to the process. The bank will give you a mailing address and instructions on what to send.

Some banks will let you use your account in a limited way while they wait for your documents — for example, you can receive money but not spend it. Others will freeze your account until verification is complete. The app will tell you what you can and cannot do.

If your verification is denied, the bank will tell you why and may offer a chance to resubmit documents or contact customer service to discuss the issue. This is rare, but it can happen if your ID is expired, damaged, or does not match the information you entered.

Frequently Asked Questions

Can I open a mobile bank account if I do not have a smartphone?

No. Mobile bank accounts require a smartphone app to open and manage. If you do not have a smartphone, a traditional bank account at a branch is a better choice. Some banks offer both branch and online options, so you could visit a branch to open an account and then manage it online later if you get a phone.

Is my money safe in a mobile bank?

Yes, if the bank is FDIC-insured. FDIC insurance protects your deposits up to $250,000 if the bank fails. Most mobile banks are FDIC-insured, but check the app or website to confirm before you open an account. The FDIC logo or statement is usually displayed prominently.

What if I lose my phone or forget my PIN?

Contact the bank's customer service through their website or by phone (the number is usually in the app). They can reset your PIN, lock your account, or help you move your money to a new phone. This is why the bank asks for a phone number and email — they use these to verify you are the account owner before making changes.

Can I use a mobile bank account for direct deposit from my job?

Yes. Give your employer the bank's routing number and your account number (both are in the app under account details), and they can deposit your paycheck directly. This usually takes one or two pay periods to set up, but once it is working, your paycheck arrives automatically on payday.

Do I need another bank account to open a mobile bank account?

You need a way to fund the account initially. Most commonly, this is a transfer from another bank account you already have. Some mobile banks let you mail in a check or use a wire transfer, but these are slower and less common. If you have no other account, ask the bank what funding options are available.
