Yes, you can add someone online at most banks, but the process and what happens next depend on your bank and the type of account

Most banks let you add an authorized user or joint owner through their website or mobile app without visiting a branch. The person you add gains access to the account — they can see the balance, make transfers, and use a debit card. However, the exact steps, the time it takes, and what permissions they receive vary by bank. Some banks complete it in minutes; others take a few business days. Before you start, know what role you want this person to have, because that changes what you can do online versus what requires a phone call or visit.

The fastest way is usually through your bank's website or app, where you will find a menu for managing account holders. You will need the person's Social Security number, date of birth, and address. If they do not have a Social Security number or if your bank has special rules for their situation, you may need to call or visit a branch instead.

Key Takeaways

  • Most banks allow you to add someone online through their website or app, but you will need their Social Security number, date of birth, and current mailing address.
  • An authorized user can use the account but usually cannot close it or change settings, while a joint owner has equal control and legal responsibility.
  • The person you add may need to verify their identity by answering security questions or confirming a code sent to their phone or email.
  • Some banks complete the process in minutes; others hold the request for one to five business days while they verify information.
  • If the person you want to add does not have a Social Security number or is a minor, you will likely need to visit a branch or call.

What information you will need before you start

Have the other person's details ready before you log in. You will need their full legal name (exactly as it appears on their ID), date of birth, and Social Security number. Most banks also ask for a current mailing address. Some banks request a phone number or email address so they can send the person a verification code or notification that they have been added.

If the person you are adding does not have a Social Security number — for example, if they are not a U.S. citizen — most banks will not let you complete this online. You will need to visit a branch or call the bank's phone line and speak to someone who can handle the request manually. The same applies if you are unsure of their exact legal name or date of birth; banks match this information against their records, and mismatches can delay or block the request.

The difference between an authorized user and a joint owner

Before you add someone, decide what level of access they need. An authorized user can use the account — they receive a debit card, can make purchases, and can see the balance and transaction history. However, they usually cannot close the account, change the account settings, remove other users, or set up bill pay. They have access but not control.

A joint owner (also called a co-owner) has equal legal rights to the account. They can do everything an authorized user can do, plus close the account, change settings, add or remove other users, and set up bill pay. Both owners are equally responsible for overdrafts or disputes. If you want to give someone full control, you need to make them a joint owner. If you want them to spend from the account but not change how it works, an authorized user is the right choice. Most banks let you choose which one you want when you add someone online.

Step-by-step: how to add someone through your bank's website or app

Log into your bank account online or open the mobile app. Look for a menu option labeled "Account Settings," "Manage Account," "Account Holders," or "Add User" — the exact wording varies by bank. Click or tap that option.

Select the account you want to add someone to if you have multiple accounts. Then choose whether you want to add an authorized user or a joint owner. Enter the person's full legal name, date of birth, Social Security number, and address. Double-check the spelling of the name and the accuracy of the date of birth, because banks verify this information against their records.

Review the information you entered, then submit the request. At this point, the bank may ask you to verify your identity — you might answer a security question, enter a code sent to your phone, or confirm recent transactions. This is the bank making sure you are the account owner and have the right to add someone. The person you are adding may receive an email or text message asking them to verify their identity as well. They might need to answer security questions, confirm a code, or log into their own banking profile. This step protects both of you by confirming that the person you named actually exists and has agreed to be added.

How long it takes and what to expect while you wait

Some banks complete the process when ready — the person appears on the account within minutes, and they can start using it right away. Other banks place a hold on the request for one to three business days while they verify the information in the background. A few banks take up to five business days. You should receive a confirmation email or notification in your app telling you when the person has been added.

While the request is pending, the person you added cannot yet use the account. If they need access urgently, ask your bank how long the hold typically lasts. If it is longer than a few days, you might consider visiting a branch instead, where staff can often complete the addition on the spot. Once the person is added, they will receive their own debit card in the mail if they are an authorized user or joint owner. This usually takes five to ten business days. Until the card arrives, they can still access the account online or through the app if your bank allows it, but they cannot make in-person purchases or withdraw cash at an ATM.

When you cannot add someone online

Some situations require a phone call or branch visit. If the person does not have a Social Security number, your bank will not let you add them through the website or app. You will need to call the bank's customer service line or visit a branch with the person present. Bring a government-issued ID for both of you.

If you want to add someone who is not yet a customer of your bank, some banks require them to open their own account first before they can be added as an authorized user or joint owner. Others allow you to add them directly. Call your bank or check their website to find out which applies to you. If you are trying to add a minor (someone under 18), most banks have special rules. Some allow it online; others require a parent or guardian to visit a branch. Check your bank's policy on minor accounts before you start.

What happens after someone is added

Once the person is on the account, they have the access level you chose. If they are an authorized user, they can spend from the account but cannot change settings. If they are a joint owner, they have the same rights you do. Both of you will see all transactions on the account, and both of you are responsible for any overdrafts or fees.

You can remove the person later through the same menu where you added them — usually under "Account Settings" or "Manage Account Holders." Most banks let you remove someone online when ready, though a few require a phone call. If you remove someone, they lose access to the account when ready, though their debit card will not work right away; it may take a day or two for the card to be deactivated.

Frequently Asked Questions

Can I add someone who does not have a bank account?

Yes. Most banks do not require the person to have an existing account with them or any other bank. However, they will need a Social Security number and a valid government-issued ID. If they do not have a Social Security number, you will need to visit a branch or call.

Will adding someone to my account affect their credit?

Adding an authorized user or joint owner does not show up on their credit report or affect their credit score. However, if the account goes into overdraft or has missed payments, those can appear on your credit report, and you are responsible for them.

Can I add someone without them knowing?

Technically you can submit the request online, but most banks send the person a notification or verification request. Even if they do not receive one, they will see the account activity once they are added. It is best to tell them first and get their permission.

What if the bank rejects my request to add someone?

Banks reject requests when information does not match their records — usually a misspelled name or wrong date of birth. Check the details and try again. If it keeps failing, call your bank; they can look up the correct information or add the person manually over the phone.

Can I add someone and limit what they can spend?

Most banks do not let you set spending limits through the online process. Some banks offer this feature through their app or by calling customer service, but it varies. Ask your bank whether they support spending limits for authorized users on your account type.
