Wells Fargo's main ABA routing number is 121000248

The ABA routing number is a nine-digit code that tells the banking system which bank to send your money to. Wells Fargo's primary routing number for most domestic transfers is 121000248. This number works for wire transfers, ACH payments (direct deposits and bill payments), and checks.

However, Wells Fargo operates multiple routing numbers depending on the type of transaction and which state your account is in. The number 121000248 is the most common one and will work for most payments, but some transactions may route through a different number. If you are sending money to a Wells Fargo account and the transfer fails, the routing number mismatch is often the culprit.

You can find the correct routing number for your specific account by checking your checks, logging into your Wells Fargo account online, calling Wells Fargo customer service at 1-800-869-3557, or visiting a branch in person. The routing number printed on the bottom left of your checks is the one tied to your specific account type and location.

Key Takeaways

  • Wells Fargo's primary ABA routing number is 121000248, which works for wire transfers, ACH payments, and most domestic transactions.
  • Your personal checks show your account's specific routing number on the bottom left, which may differ from the main number depending on your account type and state.
  • Using the wrong routing number will cause a transfer to fail or delay, so always verify before sending money.
  • You can confirm your routing number by logging into your Wells Fargo account, calling customer service, or visiting a branch.

Why Wells Fargo has multiple routing numbers

Wells Fargo uses different routing numbers for different purposes and regions. The bank operates in all 50 states and maintains separate routing numbers for some states and account types. A routing number for a Wells Fargo checking account in California may differ from one in Texas, and business accounts may route through a different number than personal accounts.

The routing number also depends on the type of transaction. Wire transfers, ACH transfers, and check processing sometimes use the same routing number, but not always. This is why the number on your checks is the most reliable source — it is tied directly to your account and will work for the transactions you actually use.

The main number 121000248 is designed to catch most transactions and route them correctly, but using your account-specific number avoids delays and failed transfers. If you are setting up a recurring payment or a wire transfer, take the extra step to find your exact routing number rather than guessing.

How to find your Wells Fargo routing number

The fastest way is to look at a check from your Wells Fargo account. The routing number is the first nine digits printed at the bottom left of the check, before your account number. If you do not have a check, log into your Wells Fargo online account or mobile app, go to your account details, and the routing number will be listed there.

You can also call Wells Fargo at 1-800-869-3557 and speak to a representative who can give you the routing number for your specific account. Have your account number ready. If you visit a Wells Fargo branch in person, any teller can provide your routing number in seconds.

Wells Fargo also publishes a full list of routing numbers by state on their website, though this list shows regional numbers rather than account-specific ones. For the most accurate number, use your checks or your online account.

When you need the routing number and when you do not

You need a routing number when someone is sending money to your Wells Fargo account — for direct deposit from an employer, a wire transfer from another bank, or an ACH payment from a business. The sender needs both your routing number and your account number to complete the transfer.

You do not need a routing number when you are sending money out of your Wells Fargo account. If you are paying a bill through your Wells Fargo online banking portal or writing a check, Wells Fargo already knows where to send the money. You only provide the routing number to people or organizations sending money to you.

If you are setting up an automatic payment from your Wells Fargo account to pay a bill, you typically do not need to enter a routing number — just your account number. But if you are asking your employer or another bank to deposit money into your Wells Fargo account, you will need to give them both the routing number and your account number.

What happens if you use the wrong routing number

If someone sends money to your Wells Fargo account using an incorrect routing number, the transfer will either fail or be delayed. The banking system may reject it outright, or it may route to a different bank or account. If the money goes to the wrong place, it can take days or weeks to trace and recover it.

Some transfers will bounce back to the sender with an error message. Others will sit in a holding account while the banks sort out where it should go. In the worst case, the money reaches a different account entirely, and you will have to contact Wells Fargo and the sending bank to retrieve it.

Always double-check the routing number before confirming a transfer, especially for large amounts or time-sensitive payments. If a transfer fails, contact Wells Fargo immediately with the transaction details so they can investigate and reroute the money if needed.

Routing numbers versus account numbers and SWIFT codes

A routing number identifies the bank. An account number identifies your specific account within that bank. Both are needed for domestic transfers. Your routing number is always nine digits; your account number is typically 10 to 12 digits and is unique to you.

A SWIFT code is different and is used only for international wire transfers. Wells Fargo's SWIFT code is WFBIUS6S. If you are receiving money from outside the United States, you will need to provide your SWIFT code, not your routing number. Some international transfers also require an IBAN (International Bank Account Number), which Wells Fargo accounts do not use — the SWIFT code and account number are sufficient.

For domestic transfers within the United States, always use the routing number. For international transfers, use the SWIFT code. Do not mix them up, as it will cause the transfer to fail.

Frequently Asked Questions

Is 121000248 the routing number for all Wells Fargo accounts?

121000248 is Wells Fargo's primary routing number and works for most accounts and transactions. However, some accounts may have a different routing number depending on the state, account type, or when the account was opened. Check your checks or your online account to confirm your specific routing number rather than assuming it is the main one.

Can I use the routing number from my checks for a wire transfer?

Yes. The routing number on your checks works for wire transfers, ACH payments, direct deposits, and most other domestic transactions. You do not need a different routing number for different transaction types — the one on your checks is your account's routing number and will work for everything.

What if I need to send money to a Wells Fargo account but do not know the routing number?

Ask the person receiving the money for their routing number — they can find it on their checks or in their online account. Do not guess or use the main number without confirming. If the recipient does not have access to their routing number, they can call Wells Fargo or visit a branch to get it.

Do I need a routing number to transfer money out of my Wells Fargo account?

No. When you are sending money out of Wells Fargo through online banking or a check, Wells Fargo already knows where to send it. You only need a routing number when someone else is sending money to your Wells Fargo account.

What is the difference between a routing number and a SWIFT code?

A routing number is for domestic transfers within the United States. A SWIFT code is for international transfers. Wells Fargo's SWIFT code is WFBIUS6S. Use the routing number for transfers from U.S. banks; use the SWIFT code for transfers from banks outside the United States.
