You can open only one Marcus savings account per person, but you can hold multiple accounts if you're the sole owner of each one and they're registered under different Social Security numbers.
Marcus by Goldman Sachs allows one savings account per Social Security number. If you try to open a second account under the same SSN, the application will be rejected. However, if you have a legitimate reason to hold multiple accounts—such as managing money for different purposes or holding accounts in different legal capacities—you may be able to do so by using different Social Security numbers, though this requires that each account be genuinely yours and not a workaround to circumvent the one-account rule.
The practical reality is that most people need only one Marcus savings account. If you're looking to separate savings by goal or purpose, you can use sub-savings within a single account or open accounts at different banks. If you're considering opening multiple accounts under different identities or SSNs, contact Marcus directly first—they can tell you whether your specific situation qualifies.
Key Takeaways
- Marcus allows one savings account per Social Security number, and applications for a second account under the same SSN will be denied.
- You cannot open multiple accounts by using the same identity or SSN, even if you give them different names or purposes.
- If you need to separate savings by goal, you can use multiple sub-savings buckets within your single Marcus account instead.
- Contact Marcus customer service before attempting to open a second account if you believe your situation is an exception.
Why Marcus limits you to one account
The one-account-per-SSN rule is standard across most online banks and is tied to how banks manage deposit insurance and fraud prevention. Each account is insured separately by the FDIC up to $250,000, so allowing unlimited accounts under one identity could create insurance complications and make it harder for the bank to monitor for fraud or money laundering.
Marcus enforces this limit during the account opening process. When you submit an application, the system checks your Social Security number against existing Marcus accounts. If a match is found, the application is rejected automatically. You won't be able to proceed, and Marcus will not override this restriction for most requests.
What you can do instead of opening a second account
If you want to organize money for different purposes—an emergency fund, a vacation, a down payment—you don't need a second account. Marcus allows you to create multiple sub-savings within your single savings account. Each sub-saving can have its own name, balance, and interest rate (all sub-savings earn the same rate as your main account). You can move money between them freely and track progress toward each goal separately.
This approach is simpler than managing two accounts and avoids the application rejection. You get the organizational benefit without hitting the one-account limit. If you need accounts at different banks for other reasons—such as comparing rates or using different features—that's a separate decision and doesn't conflict with Marcus's rules.
Situations where you might legitimately hold multiple accounts
If you are a parent or guardian managing money on behalf of a minor, you can open an account in the child's name using their Social Security number. This is a separate account from yours because it uses a different SSN. Similarly, if you are a trustee managing a trust account, that account would have its own tax ID and would be separate from your personal account.
If you are self-employed or run a business, Marcus does not currently offer business savings accounts, so you cannot open a Marcus account in your business name. You would need to use a different bank for business savings. Your personal Marcus account remains separate and is limited to one per SSN.
If you have questions about whether your specific situation—such as managing accounts for a family member or holding accounts in different legal capacities—qualifies for an exception, contact Marcus customer service. They can review your circumstances and tell you whether a second account is possible.
What happens if you try to open a second account
If you submit an application for a second Marcus savings account using the same Social Security number, the application will be rejected during the verification stage. You'll receive a notification that the application was denied, but Marcus typically does not specify that it's because an account already exists under that SSN—the rejection message is usually generic.
You cannot appeal this decision or request an override. The system is automated and tied to federal banking regulations. If you receive a rejection and believe it's an error, you can contact Marcus support to confirm that an account under your SSN already exists, but the restriction itself will not be lifted.
How FDIC insurance works across multiple accounts
If you did somehow hold multiple Marcus accounts (which you cannot), each account would be insured separately by the FDIC up to $250,000. So two accounts with $200,000 each would both be fully protected. However, this is not a reason to open multiple accounts—the FDIC insurance limit applies to the total of all your savings accounts at Marcus combined, regardless of how many you have. If you had two accounts with $150,000 each, only $250,000 total would be insured, and $50,000 would be unprotected.
Since Marcus limits you to one account per SSN, this is not a practical concern. Your single account is insured up to $250,000, and if you have more than that to save, you would need to move the excess to a different bank to keep it all insured.
Moving money between Marcus and other banks
If you want to hold savings at multiple banks—which is a valid strategy for diversifying where your money sits—you can transfer funds between Marcus and other banks using ACH transfers. These transfers typically take one to three business days and are free from Marcus. You link an external bank account to your Marcus account and initiate the transfer through the Marcus app or website.
This approach lets you use Marcus for one portion of your savings and another bank for another portion, without needing multiple Marcus accounts. You maintain full control over how much money is at each institution and can move it as needed.
Frequently Asked Questions
Can I open a Marcus account for my spouse or family member?
Yes, but only if they have their own Social Security number and open the account themselves. You cannot open an account in someone else's name. Each person is limited to one account under their own SSN. If your spouse wants a Marcus account, they can apply separately using their own identity.
What if I forgot I had a Marcus account and applied for a new one?
Your application will be rejected because an account under your SSN already exists. Contact Marcus customer service with your name and SSN, and they can help you locate your existing account. You may be able to recover access if you've lost login credentials or forgotten the account details.
Can I use a different name or nickname to open a second account?
No. The account opening process requires your legal name and Social Security number. Using a nickname or alternate name does not change your SSN, so the system will still detect that an account already exists under that number and reject the application.
Do sub-savings count as separate accounts?
No. Sub-savings are buckets within your single Marcus savings account, not separate accounts. They all share the same account number and are insured together as one account under the FDIC limit of $250,000 combined.
What if I closed my Marcus account and want to reopen one?
You can reopen a closed Marcus account by logging back in or contacting customer service. If you want to open a completely new account after closing one, you will still be limited to one account per SSN. The system does not allow you to open a second account even if the first one was closed.
