If you need your Citibank checking account routing number for a direct deposit, a bill payment, or a transfer, the tricky part is that Citibank does not use a single number for everyone. Your routing number depends on where you opened your account, and using the wrong one can delay or bounce a transaction. This guide gives you the verified numbers, shows you three fast ways to confirm yours, and explains when to use each type.
All figures below are current as of July 2026. Because banks can update routing numbers and rules over time, always confirm through your own account before sending money.

What a Routing Number Actually Is
A routing number is a nine-digit code that identifies your bank in the U.S. payment system. It tells other banks and payment networks where to send or pull money. You pair it with your account number to complete transactions like direct deposit, automatic bill pay, and account-to-account transfers.
Think of the routing number as your bank's address and the account number as your specific mailbox. Both are needed for money to reach the right place.
Citibank Routing Numbers by State
Because Citibank grew partly through regional banks, it kept multiple ACH routing numbers tied to specific areas. As of July 2026, here are commonly cited numbers by region:
- New York and Tri-State area: 021000089
- Northern California: 321171184
- Southern California: 322271724
- Florida: 266086554
- Texas: 113193532
If you opened your account online rather than at a branch, your routing number is typically the primary one for Citibank, 021000089 (New York). These figures are widely published as of July 2026, but Citibank uses roughly 55 routing numbers in total, so the safest move is to confirm yours directly through your account. If your state is not listed here, that is exactly why the verification steps below matter.
Three Ways to Confirm Your Routing Number
Do not guess. Use one of these three reliable methods to get the exact number tied to your account.
Check a paper check. Look at the bottom left corner. The first group of nine digits is your routing number, the second group is your account number, and the last group is the check number.
Log in to online banking or the mobile app. Open your checking account details or account settings. Citibank displays your routing and account numbers there, and this reflects the correct number for your specific account.
Call Citibank. Dial 1-888-248-4226 and ask a representative to confirm the routing number for your account and the transaction you are making. This is the surest option if you have no check handy and cannot log in.

ACH vs Wire: Which Number Do You Need?
This is where many people slip up. Citibank uses different numbers for different transaction types.
Use the ACH routing number for direct deposits, automatic bill payments, and standard electronic transfers. This is the regional number tied to where you opened your account, such as 021000089 for New York accounts.
Use the wire transfer routing number, 091409571, for both domestic and international wire transfers. Wires move larger sums quickly and use a separate routing path, so plugging in your ACH number for a wire, or the wire number for a direct deposit, can cause the transaction to fail.
When someone gives you a form to fill out, check whether it asks for an ACH or wire routing number and use the matching one.
When You Need Your Routing Number
You will reach for your routing number more often than you might think. Common situations include:
Setting up direct deposit from an employer or a government benefit. Enrolling in automatic payments for a loan, utility, or subscription. Sending or receiving a wire transfer. Linking your Citibank checking account to another bank, a payment app, or a brokerage. Ordering new checks or verifying a bank on a new platform.
In each case, pair the correct routing number with your account number, and double-check both before you submit.
Tips to Avoid Transfer Errors
A few habits prevent most routing mistakes. Always confirm your number through online banking or a check rather than a general list, since your specific account may differ. Match the number type to the transaction, using ACH for deposits and standard transfers and the wire number for wires. Verify the receiving details with the other party for any large transfer before sending. And keep your routing and account numbers private, sharing them only through secure, trusted channels.
