Reviewed by Calculator Editorial Team

This routing number calculator helps you find and verify routing numbers for banks in Alaska, USA. A routing number (also called an ABA number) is a 9-digit code that identifies your bank and branch for electronic transactions.

What is a routing number?

A routing number is a 9-digit code used by financial institutions in the United States to identify the bank and branch where your account is held. It's essential for electronic transactions like direct deposits, wire transfers, and online bill payments.

Key facts about routing numbers

  • Also known as an ABA routing transit number (ABA RTN)
  • Issued by the American Bankers Association (ABA)
  • Used for electronic transactions, not physical checks
  • Does not change when you move banks
  • Different from account numbers or SWIFT codes

Routing numbers are used by banks and financial institutions to process electronic payments. When you set up direct deposit, transfer money, or pay bills online, the routing number helps route the transaction to the correct bank.

How to find a routing number in Alaska

Finding your routing number in Alaska is straightforward. Here are the most common methods:

Method 1: Check your bank statement

Your routing number is typically found on the bottom of your bank statement, usually near your account number. Look for a 9-digit number labeled "ABA Routing Transit Number" or similar.

Method 2: Contact your bank

You can call your bank's customer service line and ask for your routing number. Most banks will provide this information over the phone.

Method 3: Check your checkbook

If you have a physical checkbook, your routing number is printed at the bottom of each check leaf. It's usually in the same location as on your statement.

Method 4: Online banking

Many banks allow you to view your routing number through online banking. Look for account details or a section specifically about routing numbers.

Important note

Never share your routing number with anyone unless you're initiating a transaction. Your routing number alone doesn't give anyone access to your account.

Routing number format

All routing numbers in the United States follow a specific format:

Routing number structure

A valid routing number is a 9-digit number that follows these rules:

  1. First digit: 0, 1, 2, 3, 6, 7, or 8
  2. Second digit: 0-9
  3. Third digit: 0-9
  4. Fourth to eighth digits: 0-9
  5. Ninth digit: Check digit calculated using the ABA formula

The ninth digit is a check digit calculated using the ABA's formula to ensure the routing number is valid. This helps prevent errors in electronic transactions.

How to validate a routing number

You can validate a routing number using our calculator or these steps:

  1. Check the length: Must be exactly 9 digits
  2. Verify the first digit: Must be 0, 1, 2, 3, 6, 7, or 8
  3. Calculate the check digit using the ABA formula
  4. Compare the calculated check digit with the 9th digit

ABA routing number validation formula

The check digit (9th digit) is calculated as follows:

  1. Multiply each of the first 8 digits by a weight (3,7,1,3,7,1,3,7)
  2. Sum all the weighted values
  3. Divide the sum by 10 and find the remainder
  4. Subtract the remainder from 10 (if not zero)
  5. The result is the check digit

Our calculator performs this validation automatically when you enter a routing number.

FAQ

What is the difference between a routing number and an account number?
A routing number identifies your bank, while an account number identifies your specific account at that bank. You need both for electronic transactions.
Can I change my routing number?
No, your routing number doesn't change when you move banks. It's assigned by your bank and remains the same for your lifetime.
Is my routing number the same as my SWIFT code?
No, SWIFT codes are used for international transactions, while routing numbers are for domestic US transactions.
What if I can't find my routing number?
Contact your bank's customer service. They can provide your routing number over the phone or through online banking.
Are routing numbers the same for all branches of a bank?
Yes, all branches of the same bank typically share the same routing number. The routing number identifies the bank, not the specific branch.
