Citibank's routing number depends on which state you bank in and which service you're using

Citibank does not have a single routing number for all customers. The routing number you need depends on where your account is held and what you're doing with it. If you're setting up a direct deposit, paying a bill, or sending money to another bank, you'll need the correct routing number for your specific branch or service.

The most common routing number for Citibank checking and savings accounts is 021000021, which covers most Citibank locations across the United States. However, some older accounts or accounts opened at specific branches may have different routing numbers. The fastest way to find your exact routing number is to check your checks, log into your Citibank account online, or call Citibank directly.

Key Takeaways

  • The standard Citibank routing number for most accounts is 021000021, but yours may differ depending on your account type and branch.
  • Your routing number appears on the bottom left of your checks, usually as a nine-digit code.
  • You can find your routing number by logging into your Citibank online account, calling customer service, or visiting a branch in person.
  • Using the wrong routing number can delay deposits or payments, so verify before you submit the number to your employer or another bank.

Where to find your routing number on your checks

If you have Citibank checks, your routing number is printed on the bottom left corner of each check. It's the first set of nine digits, followed by your account number and the check number on the right. The routing number always has exactly nine digits.

If you don't have checks or they're packed away, this is still the easiest place to look because you don't need to log in or call anyone. Just pull out one check and look at the bottom left.

How to find it through your Citibank online account

Log into your Citibank account on the Citibank website or mobile app. Go to your account details or account information section — the exact location varies slightly depending on whether you're using a computer or phone, but it's usually labeled "Account Details," "Account Information," or "Account Settings."

Your routing number will be listed there alongside your account number. This method works even if you don't have physical checks and is faster than calling if you're already logged in.

Calling Citibank customer service for your routing number

You can call Citibank at 1-800-CITBANK (1-800-248-2265) and ask for your routing number. A representative will verify your identity and provide it to you over the phone. This takes a few minutes but is reliable if you can't access your account online or don't have checks.

Have your account number or Social Security number ready when you call, as Citibank will ask for it to confirm who you are before giving out account details.

Different routing numbers for different account types

Most Citibank personal checking and savings accounts use the same routing number (021000021), but some accounts may have different ones. For example, if you have a very old account that was opened before a branch merger, or if you opened your account at a specific regional location, your routing number might be different.

Business accounts, investment accounts, or accounts tied to specific Citibank divisions may also use different routing numbers. If you're unsure whether your account uses the standard number, check your checks or log into your account rather than guessing.

What happens if you use the wrong routing number

If you give the wrong routing number to your employer for direct deposit, the deposit may be delayed or sent to the wrong bank. The money typically gets returned to your employer after a few days, and they can resubmit it with the correct number. This can mean waiting an extra week or more for your paycheck.

If you're sending money to another bank and use the wrong routing number, the transfer may fail or go to the wrong account. Always verify your routing number before submitting it to a new source, especially for recurring payments like direct deposit.

Frequently Asked Questions

Is 021000021 the routing number for all Citibank accounts?

It's the routing number for most Citibank personal accounts, but not all. Some older accounts or accounts opened at specific branches may have different routing numbers. Check your checks or your online account to be certain.

Can I use the same routing number for checking and savings?

Yes. Both your Citibank checking and savings accounts use the same routing number. The routing number identifies the bank and branch, not the account type.

What's the difference between a routing number and an account number?

A routing number identifies your bank and branch (nine digits). Your account number identifies your specific account at that bank (usually 10 to 12 digits). Both appear on your checks, and both are needed for direct deposits and transfers.

Do I need a routing number to use my Citibank debit card?

No. You only need a routing number when money is being sent to your account from outside Citibank — like a direct deposit from your employer or a transfer from another bank. Debit card purchases don't use a routing number.

What if my Citibank account is closed — can I still use the routing number?

No. Once your account is closed, the routing number is no longer valid for that account. If you're setting up direct deposit or transfers to a closed account, the transaction will fail or be rejected.
