The basic process: what banks require and how long it takes
To add someone to your checking account, you and the person you want to add must both visit the bank in person with valid photo ID, or you can complete the process online or by phone depending on your bank's rules. The person being added becomes either a joint account holder (equal access and ownership) or an authorized user (can use the account but you retain ownership). Most banks complete the paperwork the same day, though it can take one to three business days for the change to show up in your online banking system.
The specific steps depend on your bank. Some allow you to start the process online and finish it in a branch; others require both of you to be present from the start. A few banks let you add someone by phone and mail, but this is less common. Call your bank's customer service line or visit a branch to ask which method they use, because the rules vary widely even between branches of the same bank.
Key Takeaways
- You and the person being added both need valid photo ID, and most banks require you to be present together in person or to complete the process online through your account.
- A joint account holder has equal legal ownership and access; an authorized user can withdraw money and use the debit card but you keep ownership.
- The change usually takes effect the same day or within one to three business days, depending on your bank.
- Your bank may run a background check or credit check on the new account holder, which can delay the process by a few days.
- Once someone is added, they can see all transactions, balances, and account history unless you set up separate online login credentials.
Joint account holder versus authorized user: which one to choose
A joint account holder owns the account equally with you. They can withdraw all the money, close the account, change the account settings, and add or remove other people. If you die, the money in the account usually passes to the joint holder automatically, outside of your will. This is the right choice if you want to share finances completely with someone — a spouse, domestic partner, or adult child you trust fully.
An authorized user can use the debit card, write checks, and withdraw money, but you remain the sole owner. They cannot close the account, change the account settings, or add other people. If you die, the money does not automatically go to them. This is the right choice if you want to give someone access to spend from the account without giving them ownership — for example, a teenager, an adult child who helps with bills, or a caregiver.
Some banks use different names for these roles. Ask your bank directly: "If I add this person, can they close the account or change the account settings?" The answer tells you which type of access they will have.
What you need to bring or provide
Both you and the person being added need a valid photo ID issued by a government agency. A driver's license, passport, state ID card, or military ID all work. Some banks also accept a tribal ID. Expired IDs are usually rejected, so check the expiration date before you go.
You will need your account number, which is on your checks, your debit card, or your online banking login. If you are adding someone by phone or online, have this ready. If you are going to a branch, bring a recent statement or your debit card so the teller can pull up your account quickly.
Some banks ask for a second form of ID or proof of address (a utility bill, lease, or recent bank statement with your address on it). This is less common but does happen. Call ahead to ask what your specific bank requires.
In-person, online, and phone methods: what your bank will offer
Most large banks now let you start adding an authorized user online through your account dashboard. You enter the person's name, date of birth, and sometimes their Social Security number, then they receive an email or text asking them to confirm. This method is fastest — usually one business day — but not all banks offer it, and some only let you add a joint holder this way, not an authorized user.
Going to a branch in person is the most reliable method and works at every bank. You both show your IDs, sign the paperwork, and the change takes effect immediately or within one business day. This is the only method some smaller banks and credit unions offer. If you cannot both go at the same time, ask whether one of you can sign a power of attorney form so the other can complete it alone.
Phone-based additions are rare but some banks offer them. You call, verify your identity, and the bank mails you and the new account holder forms to sign and return. This takes one to two weeks. A few banks will accept a notarized form instead of wet signatures, which can speed this up to three to five business days if you have access to a notary.
Background checks and delays: what happens after you submit
Many banks run a background check or credit check on the new account holder before finalizing the addition. This is not a hard inquiry that affects their credit score — it is a soft check to verify identity and look for fraud flags. The check usually takes one to three business days. If the person has a common name or a history of identity theft, it can take longer.
If the check raises a question, the bank may contact you or the new account holder to confirm information. This can add another few days. In rare cases, a bank will deny the addition if the person has a serious fraud history or is on a government exclusion list, though this is uncommon.
Ask your bank upfront whether they run a check and how long it typically takes. If you need the account set up quickly, knowing this timeline helps you plan.
What happens to the account after someone is added
Once the new person is added, they can usually see the full account history, current balance, and all recent transactions. They can use the debit card, write checks, and withdraw money at an ATM or teller window. If they have online access, they can see everything you can see.
You can set up separate online login credentials so they do not see your password, but they will still see all the account activity and balances. If you want to keep some transactions private, a joint account is not the right tool — you would need a separate account.
If you add someone as an authorized user and later want to remove them, you can do so by calling the bank or visiting a branch. Removal is usually instant. If you want to remove a joint holder, the process is the same, but some banks require both of you to agree in writing.
Removing someone from the account later
To remove an authorized user, call your bank or visit a branch with your ID. You sign a form, and the removal usually takes effect immediately. The person loses access to the debit card and online login, though the bank may take one business day to process the change in their system.
Removing a joint account holder is more complicated. Some banks require both of you to sign a removal form in person. Others let the account owner remove them unilaterally. Call your bank to ask their specific policy. If the joint holder refuses to cooperate and you want them off the account, your only option may be to close the account and open a new one.
Once someone is removed, they cannot access the account, but the bank will have a record of all transactions they made while they were on it. If you suspect fraud or theft, report it to the bank immediately.
Frequently Asked Questions
Can I add someone to my account without them being present?
Some banks let you add an authorized user online without the other person present, though they will receive a confirmation email or text. For a joint account holder, most banks require both of you to be present in person or to complete the process together online. A few banks accept a notarized power of attorney form if one person cannot attend. Call your bank to ask what they allow.
Will adding someone to my account affect their credit score?
Adding someone as an authorized user or joint holder does not affect their credit score directly. The bank may run a soft background check, which does not show up on their credit report. However, if the account has a negative history or goes into overdraft, that could eventually affect their credit if the bank reports it.
What if the person I want to add does not have a photo ID?
Banks require a valid government-issued photo ID. If the person does not have one, they will need to get a state ID card or passport first. This can take several weeks depending on your state. Some banks may accept a consular ID or passport from another country if the person is not a U.S. citizen.
Can I add someone to my account if they live in a different state?
Yes. If your bank has branches in their state, you can both visit a branch there. If not, you can complete the process online or by phone if your bank offers those methods. Some banks require both people to be in the same state or to use the same branch, so call ahead to confirm.
What happens to a joint account if one person dies?
Money in a joint account usually passes to the surviving joint holder automatically, outside of probate. This is called "right of survivorship" and is the default at most banks. The surviving holder can access and use the money immediately. If you want the money to go to someone else instead, you need to change the account to a different structure or update your will, and you should talk to a lawyer about how to do this.
