Your routing number is a 9-digit code that identifies your bank for electronic transactions. You need it for direct deposit, wire transfers, automatic payments, and linking bank accounts — but finding it isn’t always obvious, especially if you don’t have checks.

Here are five reliable ways to find your routing number, ranked from quickest to most involved.

Method 1: Mobile Banking App (Fastest)

The quickest way to find your routing number is through your bank’s mobile app:

  1. Open your bank’s app and log in
  2. Tap on your checking or savings account
  3. Look for “Account details,” “Account info,” or “Direct deposit”
  4. Your routing number will be displayed with your account number

Where to find it in popular apps:

Bank Path in App
Chase Account → Show details → Routing number
Bank of America Account → Info & Services → Show full account number
Wells Fargo Account → Account details
Capital One Account → Details → Routing number
Citi Account → View account details
Ally Account → Account details
USAA Account → Direct deposit info
Navy Federal Account → Account details

Most apps let you copy the routing number directly, making it easy to paste into forms.

Method 2: Online Banking

If you prefer a larger screen, online banking works just as well:

  1. Log into your bank’s website
  2. Navigate to your account
  3. Click “Account details,” “Account information,” or a similar link
  4. Find your routing number alongside your account number

Some banks display the routing number on the main account page, while others require clicking into a details section. Look for a “Direct deposit setup” feature — it typically shows both numbers formatted for payroll.

Method 3: Check the Bottom of Your Check

If you have a checkbook, your routing number is printed on every check:

⌞ 123456789 ⌟   ⌞ 1234567890 ⌟   1234
   Routing          Account        Check
   Number           Number         Number

The routing number is the first 9 digits at the bottom-left of the check. The special bracket symbols (⌞ ⌟) help banks identify each section during check processing.

Reading order (left to right):

  1. Routing number (9 digits)
  2. Account number (varies — typically 10-12 digits)
  3. Check number (usually 3-4 digits)

Note: Some checks have the check number first (far left), then routing, then account. If you’re unsure, the routing number is always exactly 9 digits.

Method 4: Bank Statement

Your routing number may appear on your monthly bank statement:

  • Look near the top of the statement where account information is summarized
  • Check the “account details” section
  • Some banks include routing numbers in the footer

Not all banks print routing numbers on statements, but it’s worth checking if you have one handy.

Method 5: Call Your Bank or Visit a Branch

When other methods fail:

Call customer service:

Bank Customer Service Number
Chase 1-800-935-9935
Bank of America 1-800-432-1000
Wells Fargo 1-800-869-3557
Citi 1-800-374-9700
Capital One 1-800-655-2265
PNC 1-888-762-2265
US Bank 1-800-872-2657
TD Bank 1-888-751-9000
Ally 1-877-247-2559
USAA 1-800-531-8722
Navy Federal 1-888-842-6328

Have your account number and identification ready for verification.

Visit a branch: A teller can look up your routing number and provide printed confirmation. This is helpful if you need an official verification letter.

What to Avoid: Third-Party Websites

Important: While you can search “[bank name] routing number” online, be careful to use only your bank’s official website. Third-party sites may have:

  • Outdated routing numbers
  • Wrong state-specific numbers
  • Routing numbers for the wrong account type

Always verify through your bank’s app, website, or customer service before using a routing number for important transfers.

Why Banks Have Multiple Routing Numbers

Large banks often have different routing numbers for different states because they acquired smaller regional banks over the years. Each acquired bank had its own routing number, which was maintained to avoid disrupting existing customers.

Banks with state-specific routing numbers:

Banks with ONE routing number nationwide:

If your bank has state-specific numbers, use the one associated with where you opened your account — not where you currently live.

Routing Number vs. Wire Transfer Routing Number

Some banks use different routing numbers for ACH transfers versus wire transfers:

Bank ACH Routing Wire Routing
Chase State-specific 021000021
Bank of America State-specific 026009593
Wells Fargo State-specific 121000248
Capital One 051405515 051405515 (same)
Ally 124003116 124003116 (same)
USAA 314074269 314074269 (same)

For wire transfers, always confirm with your bank which routing number to use. Using the wrong one can delay your funds by several days.

Setting Up Direct Deposit

When your employer asks for direct deposit information, you’ll typically need:

  1. Routing number — your bank’s 9-digit ABA number
  2. Account number — your specific account identifier
  3. Account type — checking or savings

Some employers also request:

  • Bank name (e.g., “Chase Bank” or “Ally Bank”)
  • Bank address (use your bank’s main headquarters)
  • Voided check (as verification)

Pro tip: Most banks have a “Direct deposit form” feature in their app that generates a printable PDF with all this information.

Verifying Your Routing Number

Before using a routing number for a large transfer, verify it through multiple sources:

  1. Check against your app/online banking — the most reliable source
  2. Compare to checks or statements — should match
  3. Use ABA’s official lookuproutingnumber.aba.com for verification
  4. Call your bank — especially for wire transfers

A routing number error typically causes transfers to:

  • Fail and return to the sender (1-5 business days delay)
  • Go to the wrong institution (much harder to recover)

Taking 30 seconds to verify beats waiting days to recover misrouted funds.
