Your Amazon account number is a unique identifier separate from your email address or username

Your Amazon account number is a string of numbers that identifies your specific account in Amazon's system. It is different from your email address, your login name, or your order numbers. Amazon does not display this number prominently in your account settings, which is why many people have trouble locating it.

You can find your account number in three places: your account settings, an order confirmation email, or an invoice. The fastest route is usually your account settings, where it appears under a label like "Your Account ID" or "Account Number." If you cannot find it there, any order confirmation email from Amazon will contain the number in the header or footer.

Key Takeaways

  • Your Amazon account number is a unique identifier that appears in your account settings under "Login & security" or "Account settings," depending on your device and region.
  • Order confirmation emails from Amazon include your account number in the email header or footer, making them a reliable backup source if you cannot find it in settings.
  • Your account number is different from your order number, tracking number, or customer ID, so make sure you are looking at the correct identifier.
  • You may need your account number to contact Amazon customer service, authorize third-party apps, or troubleshoot account issues.

Finding your account number in account settings

Log into your Amazon account on a web browser or the mobile app. On the web, click the "Account & Lists" menu in the top right corner, then select "Your Account." On the mobile app, tap the menu icon (three horizontal lines) and select "Your Account."

Look for a section labeled "Login & security," "Account settings," or "Account information." The exact label varies by region and whether you are using a web browser or mobile app. Scroll down in this section until you see "Account Number," "Your Account ID," or "Customer ID." The number will be a string of digits, usually between 10 and 20 characters long. Copy or write it down exactly as it appears.

Finding your account number in order confirmation emails

Open any order confirmation email from Amazon. These emails arrive shortly after you place an order and have a subject line like "Order Confirmation" or "Your Amazon.com order of [item name]."

Scroll to the very top or very bottom of the email. Your account number typically appears in the email header (above the main message) or footer (below the order details). It may be labeled "Account Number," "Customer ID," or "Amazon Account ID." If you cannot find it in the header or footer, scroll through the order details section — some regions display it near your shipping address or payment method.

Finding your account number on an invoice

Go to "Your Orders" in your account settings. Find any order and click "Invoice" or "View Invoice." A PDF or printable page will open showing your order details.

Your account number appears on the invoice, usually near the top or bottom of the page alongside your order number and order date. The invoice label may say "Account Number," "Customer ID," or "Account ID." Write down the number exactly as it appears on the invoice.

What to do if you cannot find your account number

If you have checked account settings, order emails, and invoices and still cannot locate your account number, contact Amazon customer service directly. You can reach them through the "Contact Us" link at the bottom of any Amazon page, or by calling the phone number listed for your region.

When you contact Amazon, have your email address and a recent order number ready. Customer service can confirm your account number over the phone or email. They may also ask you to verify your identity by answering security questions or confirming details from a recent order.

Why you might need your Amazon account number

Amazon customer service sometimes asks for your account number when you contact them about an issue. Third-party apps or services that integrate with Amazon may also request it to authorize access to your account. Some payment or subscription services linked to Amazon use your account number as a reference.

You do not need your account number for everyday shopping or account management. It is mainly useful when troubleshooting problems, authorizing external services, or speaking with customer service representatives who need to pull up your account quickly.

Frequently Asked Questions

Is my account number the same as my order number?

No. Your account number identifies your entire Amazon account, while your order number identifies a single purchase. Order numbers are shorter and appear on receipts and tracking pages. Your account number is longer and appears in account settings or email headers.

Can I change my Amazon account number?

No. Your account number is assigned by Amazon when you create your account and cannot be changed. It is a permanent identifier for your account in their system.

Is it safe to share my account number?

Your account number alone is not sensitive information — it does not grant access to your account the way your password does. However, avoid sharing it with people you do not trust. If Amazon customer service asks for it, verify you are speaking with an official Amazon representative before providing it.

What if I have multiple Amazon accounts?

Each Amazon account has its own unique account number. If you manage more than one account, each one will have a different number. Log into each account separately to find its specific account number.
