What a routing number is and why you need it

A routing number is a nine-digit code that identifies which bank or credit union holds your account. Banks use it to send money to the right place — whether you're setting up direct deposit from your employer, paying a bill by check, or transferring money between accounts. Without the correct routing number, a transfer can go to the wrong bank or get delayed.

Citibank has multiple routing numbers because different branches, regions, and account types sometimes use different codes. The routing number you need depends on where your account is located and what you're trying to do.

Key Takeaways

  • Citibank routing numbers are nine-digit codes that vary by state and account type, so you need to find the one for your specific branch location.
  • You can find your routing number on the bottom left of your checks, in your online banking portal, or by calling Citibank customer service.
  • The routing number for a wire transfer may differ from the one for direct deposit or ACH transfers, so confirm which type of transaction you're making.
  • If you use a Citibank branch in a different state than where you opened your account, verify the routing number for that specific location.

How to find your routing number on a check

The easiest way to locate your routing number is to look at a check from your Citibank account. On the bottom left corner of the check, you'll see three groups of numbers separated by colons or special symbols. The first group — the leftmost nine digits — is your routing number.

If you don't have a check handy or prefer not to order one, this method won't work, but the other methods below are faster anyway.

Finding your routing number online or by phone

Log into your Citibank online banking account and navigate to your account details or settings. Many accounts display the routing number directly, though the exact location varies depending on whether you use Citi's main website or a mobile app. Look for sections labeled "Account Information," "Bank Details," or "Routing and Transit Numbers."

If you can't locate it online, call Citibank customer service at the number on the back of your debit or credit card. A representative can tell you the routing number for your specific account and branch in less than a minute. Have your account number ready when you call.

Different routing numbers for different transaction types

Citibank may use one routing number for ACH transfers (like direct deposit or bill payments) and a different one for wire transfers. Wire transfers are faster but more expensive, and they sometimes route through different processing centers than ACH payments.

Before you provide your routing number to an employer, payroll service, or bill-pay company, confirm which type of transaction they're setting up. If they ask for a routing number without specifying, it's safe to assume they mean ACH, which is the standard for direct deposit and most bill payments.

Routing numbers by state and account type

Citibank's routing numbers are organized by state and sometimes by the type of account you hold. A checking account in New York may have a different routing number than a savings account in California, even if both are Citibank accounts. This is why calling customer service or checking your online account is more reliable than searching for a general "Citibank routing number" — the one you find might not be the one you need.

If you've recently moved or opened an account at a different branch, double-check that you're using the routing number for your current account location, not your old one.

What to do if the routing number doesn't work

If you provide a routing number and the transfer fails or takes longer than expected, the number may have been incorrect or outdated. Contact Citibank when ready to confirm the right routing number for your account. If the money has already been sent, the bank can sometimes trace it and reroute it, but this process takes time.

When you get the correct number, ask the person or company receiving it to resubmit the transfer. For direct deposit, your employer's payroll department can update your information and reprocess the deposit for the next pay period.

Frequently Asked Questions

Is the routing number the same for all Citibank accounts?

No. Citibank routing numbers vary by state and sometimes by account type. Even two Citibank customers in the same city may have different routing numbers if their accounts are set up differently. Always verify the routing number for your specific account rather than using one you find online.

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

Sometimes, but not always. Wire transfers and ACH transfers (like direct deposit) may use different routing numbers at Citibank. Before setting up either type of transaction, confirm with your bank which routing number applies. Using the wrong one can cause delays or failed transfers.

What if I don't have checks and can't log into online banking?

Call Citibank customer service using the number on the back of your debit card or from the Citibank website. A representative can provide your routing number over the phone in minutes. Have your account number and a form of identification ready.

Do I need a different routing number if I moved to another state?

It depends on your account. If you moved but kept the same Citibank account, your original routing number may still work. However, if you opened a new account at a Citibank branch in your new state, that account will have its own routing number. Check your new account details to be sure.
