What an ACH Number Is and Why Chase Customers Might Need It

An ACH number isn't something most people think about until they need to move money between banks or set up automatic payments. ACH stands for Automated Clearing House, which is the electronic system that processes bank-to-bank transfers in the United States. When you send money from your Chase account to another bank, or when someone sends you money from their bank into Chase, an ACH transaction is happening behind the scenes.

Chase Bank uses routing numbers and account numbers rather than a standalone "ACH number" per se. However, understanding how these numbers work together is essential for anyone who regularly transfers money electronically. Your Chase routing number identifies which Chase branch or processing center handles your account, while your account number identifies which specific account the money should go to. Together, these two pieces of information make up what people often casually refer to as your ACH routing information.

According to the Federal Reserve, in 2022 alone, more than 29 billion ACH transactions moved over $68 trillion between accounts. That's a massive number of everyday transfers—payroll deposits, bill payments, peer-to-peer transfers, and business payments. Chase processes a significant portion of these transactions for its 75 million active users.

The reason you might need this information varies. Maybe your employer requires your banking details to set up direct deposit. Perhaps you're receiving a tax refund and need to provide your bank details to the IRS. You could be setting up recurring bill payments with a utility company, or you might be paying a freelancer or contractor who needs your account information for an invoice payment.

Takeaway: Know that Chase doesn't issue a separate "ACH number"—you'll use your routing number and account number together for electronic transfers. Keeping these numbers handy saves time when you need them.

How to Find Your Chase Routing Number

Your Chase routing number is a nine-digit code that identifies your specific Chase location or processing center. The number varies depending on which state your account was opened in and which type of account you have. Chase maintains different routing numbers for different regions and account types, which is why you can't just use a single Chase routing number for everyone.

The most straightforward way to find your routing number is to look at the bottom left corner of any check from your Chase checking account. The first nine digits you see are your routing number. If you don't have checks readily available, you can log into your Chase online banking portal or mobile app. Once logged in, navigate to your account details or account settings. Most checking accounts display the routing number in the account information section.

You can also call Chase customer service at 1-800-935-9935 and speak with a representative who can provide your routing number. Be prepared to verify your identity with information like your account number, Social Security number, or other account details.

Chase's official website maintains a routing number lookup tool. You can visit Chase.com, search for "routing number," and use their tool to look up the correct routing number for your specific account type and location. This tool is particularly useful if you've moved or changed account types and want to confirm you have the current information.

Common Chase routing numbers include 021000021 for many East Coast locations, 322271627 for some Midwest locations, and 111000025 for some West Coast branches, though these vary by your specific location. Always verify the exact number for your account rather than assuming.

Takeaway: Your check, online banking portal, the Chase website lookup tool, or a phone call to Chase can all provide your routing number. Write it down once and save it somewhere secure for future reference.

Locating Your Chase Account Number

Your Chase account number is the unique identifier for your specific bank account. This is a separate piece of information from your routing number, though they work together for ACH transfers. Your account number typically consists of 10 to 12 digits, though the exact length can vary.

The easiest place to find your account number is on your checks. Look at the bottom of the check—after the nine-digit routing number, you'll see your account number. It's printed there for exactly this reason: so you can reference it when needed.

Log into your Chase online banking account on a computer or through the Chase mobile app on your phone. Once you're in your account dashboard, look for sections labeled "Account Information," "Account Details," or "Account Summary." Your account number appears prominently in these sections. The mobile app typically shows it right on the main account screen without needing to navigate through additional menus.

When you call Chase customer service, they can confirm your account number after verifying your identity. This is useful if you need reassurance that you have the correct number or if you've misplaced your information.

Some people worry about sharing their account number for ACH transactions, but this is a normal and safe part of banking. Your account number alone cannot be used to withdraw money—someone would also need your routing number, and even then, ACH transfers have built-in security checks and can take several business days to process, giving you time to notice unauthorized activity.

Takeaway: Your account number is on your checks and in your online banking account information. Keep a copy in a safe, secure place where you can find it quickly when you need to set up transfers or provide it to employers, government agencies, or service providers.

What Information You Should Prepare to Share

When you're ready to set up an ACH transfer or provide your banking information to someone who needs to send you money, having the right information organized beforehand prevents delays and errors. The basic information you'll need is your routing number, your account number, and your account type.

Your account type refers to whether you have a checking account or a savings account with Chase. This matters because ACH transfers go to different accounts depending on which type you specify. If you're setting up direct deposit for your paycheck, you'll typically use a checking account. If you're redirecting a tax refund, you might use either type depending on your preference.

Some situations require additional information. If you're setting up ACH transactions through a third-party website or service—not directly with Chase or your employer—that service may ask for your name as it appears on the account, your address associated with the account, and possibly a phone number or email. These details help verify that the person initiating the transfer actually owns the account.

When providing this information to set up direct deposit with a new employer, you might be filling out a form that asks for your bank name (Chase), your branch location or state, your routing number, your account number, and your account type. Different employers use different forms, so don't be surprised if some ask for more details than others.

Be cautious about where you share this information. Reputable organizations—banks, employers, government agencies, major utility companies—are the appropriate places to share your routing and account numbers. You should never share this information through unsolicited emails, texts, or phone calls, even if they claim to be from your bank.

Takeaway: Organize your routing number, account number, and account type in one place. When asked for banking information, provide only what's requested, and only through official channels you've initiated contact with.

Understanding ACH Transfer Timelines and Processing

Once you've provided your Chase banking information for an ACH transfer, the actual movement of money follows a predictable pattern, though it's slower than many people expect. ACH transfers typically take three to five business days to complete, even though the transaction is electronic. This isn't Chase being slow—it's how the entire ACH system is designed across all banks in the United States.

Here's what happens during those three to five days. When a transfer is initiated, it enters the ACH processing queue. The ACH network, operated by Nacha (formerly the National Automated Clearing House Association), processes batches of transactions at set times during the day. Your specific transaction gets grouped with thousands of others and sent to the receiving bank. That bank then processes incoming transfers in batches as well, verifying account numbers and taking steps to prevent fraud. Finally, the money appears in the receiving account.

Business days matter here—that means weekdays excluding federal holidays. If you initiate a transfer on Friday afternoon, it typically won't begin processing until Monday. If Monday is a federal holiday, processing might not start until Tuesday. This is why urgent transfers aren't handled through ACH; they're handled through
