Your Amazon account number is a unique identifier separate from your email address or login name
Your Amazon account number is a string of numbers Amazon assigns to your account when you create it. It is not the same as your email address, your password, or your order number. You will need this number if you contact Amazon customer service, dispute a charge, or link your account to a third-party service.
The fastest way to find it is through your Amazon account settings on the website or app. Amazon does not display it prominently — it is tucked into a page most people never visit — but it takes less than a minute to locate once you know where to look.
Key Takeaways
- Your account number appears in the Account Settings section under "Login & security" on the Amazon website.
- On the Amazon app for phone or tablet, the account number is in the "Your Account" menu under the same "Login & security" heading.
- If you cannot find it in settings, customer service can tell you your account number in seconds.
- Your account number is different from your order numbers, which start with a # symbol and appear on receipts and shipping confirmations.
Finding your account number on the Amazon website
Open Amazon.com in your web browser and sign in with your email and password. Once you are logged in, move your cursor to the top right corner where you see "Account & Lists" and click it. A dropdown menu will appear.
From that menu, click "Your Account." This takes you to your account dashboard. On the left side of the page, you will see a menu with several options. Look for "Login & security" and click it. Scroll down on this page until you see a section labeled "Account" or "Account Information." Your account number will be displayed there as a long string of numbers.
Write down or copy this number somewhere safe. You may need it for customer service calls, refund disputes, or when linking your Amazon account to other services like Alexa or a third-party app.
Finding your account number on the Amazon mobile app
Open the Amazon app on your phone or tablet and sign in if you are not already logged in. Tap the menu icon — usually three horizontal lines in the bottom right corner — to open the navigation menu. Tap "Your Account" from the list of options.
On the Your Account page, scroll down until you see "Login & security." Tap it to expand that section. Your account number will appear below the heading, usually near the top of the expanded section. The number is typically 10 to 12 digits long.
If the app layout has changed or looks different on your device, look for any section labeled "Account Information" or "Account Details" — the account number is always filed under one of these headings.
What to do if you cannot locate it in settings
If you have looked in Login & security and do not see the account number, or if the page layout on your device is different, contact Amazon customer service directly. They can retrieve your account number in seconds without asking you to verify anything beyond your email address.
You can reach Amazon customer service through the "Contact Us" link at the bottom of any Amazon page, or through the "Help" section in your account menu. Choose the option to chat with a representative or request a call, and tell them you need your account number. They will provide it immediately.
The difference between your account number and your order number
Many people confuse their account number with their order number. These are two separate things. Your order number is a unique identifier for each individual purchase you make. It starts with a # symbol and appears on your order confirmation email and on your receipt. Your account number, by contrast, is tied to your entire Amazon account and never changes.
If you are looking for a specific order, search for the order number instead. If you need to contact Amazon about your account itself — such as a billing dispute or account security issue — you will need the account number.
Why Amazon asks for your account number
When you call or chat with Amazon customer service, they may ask for your account number to pull up your account faster. Providing it saves time because the representative can verify your account without asking multiple security questions. However, they can also look up your account using your email address alone, so not having the number handy is not a problem.
Some third-party services and apps that connect to Amazon — such as smart home devices or shopping assistants — may also ask for your account number during setup. This is normal and safe. Never share your account number with anyone you do not trust, and never enter it on a website that does not look official.
Keeping your account number safe
Your account number is not as sensitive as your password, but you should still treat it as private information. Do not post it on social media or share it in public forums. If you are writing it down, keep the note in a safe place alongside other important account information.
If you suspect someone has your account number and you are worried about unauthorized access, change your Amazon password immediately. You can do this in the same Login & security section where you found your account number. A strong password — one with uppercase and lowercase letters, numbers, and symbols — is your best defense against account takeover.
Frequently Asked Questions
Is my account number the same as my customer ID?
Yes, Amazon uses these terms interchangeably. Your account number and customer ID are the same thing — a unique identifier assigned to your account. You may see it called either name depending on which Amazon page or service you are using.
Can I change my account number?
No, your account number is permanent and cannot be changed. It is assigned when you create your account and stays the same for the life of that account. If you want a fresh start, you would need to create a new Amazon account, which would generate a new account number.
What if I forgot my Amazon password and cannot log in?
You cannot access your account number without logging in. Go to Amazon.com and click "Sign in" at the top. Click "Forgot password?" and follow the steps to reset it using your email address. Once you have reset your password and logged back in, you can find your account number in Login & security as described above.
Do I need my account number to make a purchase?
No, you do not need your account number to shop on Amazon. You only need your email address and password to log in and place an order. The account number is useful for customer service, billing disputes, and linking external services, but not for everyday shopping.
Where do I find my account number on an old Amazon receipt?
Your account number does not appear on receipts or order confirmation emails. Those emails show your order number instead. To find your account number, you must log into your Amazon account and go to Login & security in your account settings.
