Citibank's routing number depends on which state you bank in and what type of transaction you're making

Citibank does not have a single routing number for all customers. The routing number you need depends on where your account is held and whether you're setting up a wire transfer, ACH transfer, or direct deposit. For most Citibank checking and savings accounts opened in New York, the routing number is 021000021. However, if your account is in a different state or you're making a specific type of transfer, you may need a different number.

The routing number is a nine-digit code that tells the banking system which financial institution holds your account. Banks use it to process transfers between accounts, direct deposits from employers, and bill payments. Using the wrong routing number can delay your transaction or send money to the wrong place, so it's worth taking the time to find the correct one for your situation.

Key Takeaways

  • Citibank's primary routing number for New York accounts is 021000021, but other states and account types may use different numbers.
  • You can find your specific routing number by logging into your Citibank account online, calling customer service, or checking the bottom left of your checks.
  • Wire transfers, ACH transfers, and direct deposits may each require different routing numbers depending on how Citibank processes them.
  • The routing number is different from your account number and should never be shared with untrusted sources.

How to find your routing number through Citibank online

The fastest way to find your correct routing number is to log into your Citibank account on their website or mobile app. Once you're signed in, look for account details or account information. Citibank typically displays your routing number alongside your account number in this section. The exact location varies slightly between the website and the app, but it's usually labeled clearly as "routing number" or "ABA number" (ABA stands for American Bankers Association).

If you can't locate it online, call Citibank customer service at the number on the back of your debit card. A representative can confirm your routing number over the phone and can also tell you if you need a different number for the specific transaction you're planning. This is especially useful if you're setting up a wire transfer, since wire routing numbers sometimes differ from ACH routing numbers.

Checking your paper checks for the routing number

If you have Citibank checks, the routing number is printed at the bottom left of each check. It's the first set of nine digits, followed by your account number and then the check number. This method works if you have checks on hand, but it's not always reliable if you've had your account for several years, since routing numbers can change when banks merge or reorganize their operations.

The routing number on your checks is usually correct for standard ACH transactions and direct deposits. However, if you're initiating a wire transfer, confirm with Citibank first that this is the right number to use, since some banks maintain separate routing numbers for wire transfers.

Routing numbers for different types of Citibank transactions

Citibank may use different routing numbers depending on how money is moving. For ACH transfers (electronic transfers between bank accounts that take one to three business days), the routing number is typically 021000021 for New York-based accounts. For wire transfers (faster transfers that usually complete the same day), Citibank sometimes uses a different routing number, so you should confirm with the bank before sending a wire.

Direct deposits from your employer also use a routing number, and in most cases it's the same one as your ACH transfers. However, some employers' payroll systems have outdated information, so if your direct deposit is delayed or failing, ask your employer's payroll department to verify they have the current Citibank routing number on file.

If you're receiving a transfer from outside the United States, you may need Citibank's SWIFT code instead of a routing number. The SWIFT code for Citibank is CITIUS33, and it's used for international wire transfers.

Routing numbers for different states and account types

Citibank operates in multiple states, and some states have their own routing numbers. The routing number 021000021 covers most Citibank accounts in New York and many other states. However, if your account was opened in California, Florida, Texas, or another state, Citibank may have assigned a different routing number. The best way to confirm is to check your account online or call customer service with your account number and ZIP code.

Citibank also offers business accounts, which may use different routing numbers than personal accounts. If you have a business checking account with Citibank, verify your routing number through your business account portal or by calling Citibank's business banking line.

What to do if a transfer fails or is delayed

If money you sent to a Citibank account hasn't arrived, the routing number is often the culprit. Double-check that you used the correct nine-digit number and that you didn't accidentally transpose any digits. If the routing number was wrong, contact the bank or financial institution that sent the money and ask them to trace the transfer. Some transfers can be recalled or rerouted if caught quickly enough.

If the routing number was correct but the transfer is still delayed, it may be held up by the sending bank, Citibank's fraud detection system, or a mismatch between the account number and the name on the account. Contact Citibank directly with the transfer details (the amount, the date sent, and the sending bank) and they can investigate on their end.

Frequently Asked Questions

Is the routing number on my Citibank checks always correct?

Usually, yes, but not always. Routing numbers can change if Citibank merges with another bank or reorganizes its operations. If your checks are more than a few years old, confirm the routing number online or by phone before using it for an important transfer.

Can I use the same routing number for wire transfers and ACH transfers?

In most cases, yes. However, some banks maintain separate routing numbers for wire transfers. Before sending a wire, contact Citibank to confirm you have the correct routing number for that specific transaction type.

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

The routing number identifies which bank holds your account (Citibank, in this case). Your account number identifies your specific account within that bank. You need both numbers to send or receive money, and they appear together at the bottom of your checks.

Do I need a different routing number if I have multiple Citibank accounts?

No. All your Citibank accounts in the same state typically share the same routing number. The account number is what distinguishes one account from another.

What should I do if I don't have checks and can't access my account online?

Call Citibank customer service at the number on the back of your debit card. Have your account number and identification ready, and they'll provide your routing number over the phone.
