A linked account is another bank account you connect to your main account so money can move between them automatically or on demand
When you link an account, you're telling your bank or payment service that you own or control both accounts and want to move money between them without entering account details each time. The linked account can be at the same bank or a different one. Once linked, you can transfer funds, set up automatic payments, or receive deposits to either account using a single login.
The connection itself is not automatic money movement — it's permission. You still decide when and how much to transfer. But because the accounts are already verified and connected in the system, the transfer happens faster and with fewer steps than sending money to an unlinked account.
Key Takeaways
- Linking an account means connecting two accounts you own so you can move money between them without re-entering account numbers each time.
- The linked account can be at your own bank or at a completely different bank, and you control when and how much money moves.
- Your bank verifies both accounts belong to you before the link is active, usually by checking small test deposits or asking security questions.
- Transfers between linked accounts typically clear within one business day, faster than transfers to accounts you have not linked.
- You can unlink an account at any time through your bank's website or app, and the accounts remain separate and functional.
How the linking process works
To link an account, you log into your bank's website or mobile app and find the transfer or linked accounts section. You enter the account number and routing number (for a U.S. bank account) or the equivalent details for an account outside the U.S. Your bank then verifies that you control the account you're linking.
Verification usually happens one of two ways. Some banks deposit two small amounts — typically under one dollar each — into the account you're linking. You then log into that account, find the deposit amounts, and enter them back into your original bank's system to confirm you can access it. Other banks skip the deposits and instead ask security questions or send a verification code to a phone number or email on file for the linked account.
Once verified, the link is active and you can transfer money when ready. The entire process usually takes between one and three business days from start to finish, though some banks complete it faster if you link an account at the same institution.
Why you would link an account
The main reason is convenience. If you have a checking account for daily spending and a savings account for emergencies, linking them means you can move money between them without writing down numbers or copying details. You can also set up automatic transfers — for example, moving a fixed amount to savings every payday — without re-entering the account information each time.
Linked accounts also speed up transfers. Because your bank has already verified both accounts belong to you, the transfer clears faster than sending money to an unlinked account at another bank, which may take two to three business days. If you need to move money quickly — to cover an overdraft or fund an unexpected expense — a linked account gets the money there sooner.
Some people link accounts at different banks to consolidate money in one place, to keep separate accounts for different purposes (one for bills, one for savings, one for a side business), or to manage money for someone else with their permission.
The difference between linked and unlinked accounts
| Aspect | Linked Account | Unlinked Account |
|---|---|---|
| Setup time | 1 to 3 business days (verification required) | None — you can transfer when ready |
| Transfer speed | Usually 1 business day | 2 to 3 business days (or longer for some banks) |
| Information needed | Account and routing number (verified once) | Account and routing number (entered each time) |
| Automatic transfers | Can set up recurring transfers | Must enter details each time |
| Security check | Bank verifies you own both accounts | No verification — you confirm details yourself |
The trade-off is that linking takes a few days upfront because your bank needs to confirm you control both accounts. But once that's done, every transfer is faster and requires fewer steps. With an unlinked account, you can transfer when ready, but you'll enter the account details every time and wait longer for the money to arrive.
What happens when you unlink an account
Unlinking an account is straightforward and reversible. You go to the linked accounts section of your bank's app or website, find the account you want to remove, and select unlink or delete. The connection is severed when ready, and the account itself remains open and functional at its bank.
Once unlinked, you can no longer use that account for automatic transfers from your main account, and any transfers you make to it will be treated as transfers to an unlinked account — meaning they'll take longer and you'll need to re-enter the account details. You can link the account again at any time by going through the verification process a second time.
Unlinking does not close the account, freeze it, or affect its balance. It only removes the shortcut connection between the two accounts in your bank's system.
Security considerations when linking accounts
Linking an account is generally safe because your bank verifies you own both accounts before the link becomes active. You're not giving the bank access to the linked account — you're proving you have access to it. The verification step (small deposits or security questions) ensures that someone who has stolen your login credentials cannot link accounts without also having access to the account being linked.
However, you should only link accounts you own or accounts you have explicit permission to manage. Linking someone else's account without their knowledge or consent is fraud. If you manage money for a family member or business partner, they should be aware of the link and approve it.
If you notice a linked account you did not create, unlink it when ready and contact your bank. This is rare but can happen if someone has compromised your login. Your bank can also review the transfer history to see if any unauthorized transfers occurred.
Linked accounts across different banks
You can link accounts at different banks using the same process. When you link an account at Bank A to an account at Bank B, Bank A verifies the Bank B account details and confirms you can access it. The two banks do not communicate directly — the verification happens between you and Bank A.
Transfers between accounts at different banks typically take one business day, though some banks offer faster options (sometimes called "next-day" or "same-day" transfers) for an additional fee. The speed depends on the banks involved and the time of day you initiate the transfer. A transfer sent before 2 p.m. on a weekday may clear the next morning; one sent after hours or on a weekend may take longer.
Linking accounts across banks is useful if you have accounts at multiple institutions and want to consolidate money without visiting each bank separately or paying transfer fees.
Frequently Asked Questions
Can I link an account that someone else owns?
No, not without their knowledge and permission. Your bank will ask you to verify you own or control the account being linked. If you need to manage someone else's account, they should add you as an authorized user or co-owner, or they should link it themselves and give you access through a power of attorney or similar legal arrangement.
Does linking an account cost money?
Linking an account itself is free at most banks. Some banks charge a fee for expedited transfers (same-day or next-day) between linked accounts, but standard transfers are included in your account. Check your bank's fee schedule or ask customer service about any charges before linking.
How many accounts can I link?
Most banks allow you to link multiple accounts, though the exact number varies by institution. Some banks limit you to 5 or 10 linked accounts; others have no stated limit. If you need to link many accounts, contact your bank to confirm their policy.
What if the account I'm trying to link is closed?
Your bank will reject the link during verification if the account is closed. The verification process checks that the account is active and accessible. If you're trying to link a closed account, you'll need to link an active account instead or contact the bank that holds the closed account to reopen it.
Can I link an account at a credit union?
Yes, you can link accounts at credit unions the same way you link accounts at banks. You'll need the credit union account number and routing number. The verification process is identical, and transfers between a bank and a credit union account work the same way as transfers between two banks.
