Finding Your Bank of America California Routing Number
Bank of America uses different routing numbers depending on which state you bank in and which type of transaction you're making. For California customers, the routing number you need depends on whether you're sending a domestic wire transfer, an ACH transfer, or a check. The most commonly used routing number for Bank of America in California is 121000248, which works for most domestic wire transfers and ACH payments.
Your specific routing number may differ based on which Bank of America branch you opened your account with or which service you're using. The safest way to confirm the correct number is to check your own checks — the routing number appears in the bottom left corner — or to call Bank of America directly at 1-800-432-1000 and ask for your account's routing number.

Why Routing Numbers Matter for Wire Transfers
A routing number tells the banking system which financial institution should receive your money. When you send a wire transfer, the routing number directs the funds to the correct Bank of America branch or processing center. Using the wrong routing number can delay your transfer by days or send it to the wrong bank entirely, which then has to be traced and corrected.
Wire transfers are different from ACH transfers or checks — they move faster and are harder to reverse, so getting the routing number right the first time matters. The receiving bank uses the routing number to identify Bank of America as the destination, and then uses your account number to deposit the funds into your specific account.
Common Bank of America Routing Numbers in California
Bank of America maintains multiple routing numbers across California because the bank has processing centers in different regions. The routing number 121000248 is the most widely used for California customers sending domestic wire transfers. However, some older accounts or accounts opened at specific branches may use 026009593 or other numbers.
If you're receiving a wire transfer into your Bank of America California account, the sender will need your routing number. Always provide the number from your checks or from your online banking portal rather than guessing, because even one digit wrong will cause the transfer to fail or go to the wrong place.
How to Find Your Routing Number Online
Log into your Bank of America online banking account and go to the account details or account information section. Most accounts display the routing number alongside your account number. You can also look at any recent bank statement — the routing number appears at the bottom of the page along with your account number.
If you don't have online access set up, you can call Bank of America's customer service line at 1-800-432-1000. Have your account number and a form of identification ready. The representative will confirm your routing number and can also tell you if your account uses a non-standard routing number due to how or where you opened it.
Routing Numbers for Different Transaction Types
Bank of America may use different routing numbers depending on whether you're sending a wire transfer, an ACH transfer, or paying by check. Wire transfers typically use the main routing number, but ACH transfers (which are slower and less expensive) sometimes use a different routing number. When you're setting up a payment through a third party — like paying a bill online or sending money through a payment app — the system usually asks you to choose the transaction type, and the correct routing number is selected automatically.
If you're manually entering a routing number for a wire transfer, use the number from your checks or from your Bank of America account information. Do not use a routing number from a different bank or a different state, even if you think it might work — the transfer will fail or be rejected.
What to Do If Your Wire Transfer Is Delayed
If you sent a wire transfer and it hasn't arrived after one business day, contact Bank of America immediately at 1-800-432-1000. Have the wire transfer confirmation number ready — this is the reference number Bank of America gave you when you sent the transfer. Tell the representative the amount, the receiving bank's name, and the date you sent it.
The bank can check whether the transfer left your account and where it went. If the routing number was wrong, the receiving bank may have rejected it and sent it back to Bank of America, which can take several days. If the transfer went to the wrong bank, Bank of America can attempt to recall it, though success depends on whether the receiving bank has already processed it.
Frequently Asked Questions
Is 121000248 the routing number for all Bank of America customers in California?
121000248 is the most common routing number for Bank of America in California, but not all accounts use it. Accounts opened at certain branches or older accounts may have a different routing number. Check your checks or your online account information to confirm your specific number rather than assuming.
Can I use the same routing number for a wire transfer and an ACH transfer?
Sometimes, but not always. Wire transfers and ACH transfers may use different routing numbers depending on your account. When you initiate a transfer through your bank or a payment system, the correct routing number is usually selected automatically based on the transfer type. If you're entering it manually, confirm with Bank of America which number to use for your specific transaction.
What happens if I use the wrong routing number?
The transfer will either be rejected by the receiving bank and returned to you, or it will go to the wrong financial institution. Either way, the money doesn't reach the intended recipient. Contact Bank of America with your confirmation number so they can trace where the transfer went and attempt to recover it.
Do I need a different routing number if I'm sending money to someone outside California?
No. The routing number identifies Bank of America as your bank, not the location of the recipient. Use your California Bank of America routing number whether you're sending money within California, to another state, or internationally. International transfers may require additional information like a SWIFT code, but the routing number stays the same.
Where do I find the routing number if I don't have checks or online access?
Call Bank of America customer service at 1-800-432-1000 with your account number and identification ready. A representative can provide your routing number immediately. You can also visit a Bank of America branch in person with your ID and ask for your routing number.
