How to Find Your Amazon Account Number (And What It Actually Means)

If you've been searching for your "Amazon account number," you're likely trying to accomplish something specific — verifying your identity, filling out a form, or troubleshooting an issue. The answer depends on which identifier Amazon actually uses for your account, because the term "account number" isn't straightforward on Amazon's platform.

Amazon Doesn't Use a Traditional "Account Number"

Unlike a bank or credit card account, Amazon doesn't assign a single visible account number that you regularly reference. Instead, Amazon uses several different identifiers depending on the context — your registered email address, your customer ID, your AWS Account ID (if you use Amazon Web Services), and others.

Understanding which one applies to your situation is the key first step.

The Most Common Identifiers on Amazon

1. Your Registered Email Address (Most Common)

For the vast majority of Amazon.com shoppers, your email address is your account identifier. When Amazon support, a third-party seller, or any form asks for your "account," they typically want your registered email address. This is the most universally accepted way to identify your Amazon retail account.

You can verify or find this by:

  • Logging into Amazon.com
  • Hovering over "Account & Lists" in the top-right corner
  • Clicking "Account"
  • Selecting "Login & security" — your registered email is displayed here

2. Amazon Customer ID

Amazon does assign each retail account a unique Customer ID, sometimes called a Buyer ID. This isn't prominently displayed on the site, but it can surface in certain contexts — particularly in marketplace transactions or developer-facing tools.

You can sometimes find a version of this in order confirmation emails or by accessing your account data through Amazon's data request tool:

  • Go to Account > Data and Privacy > Request My Data
  • Amazon will compile a downloadable file that includes your customer ID and other account-level information

This process typically takes a few days to complete.

3. AWS Account ID (Amazon Web Services)

If you use Amazon Web Services — cloud computing, storage, hosting, or developer tools — then you do have an actual numeric AWS Account ID. This is a 12-digit number unique to your AWS account and is used frequently for billing, IAM policies, and inter-account resource sharing.

To find your AWS Account ID:

  • Sign in at aws.amazon.com
  • Click your account name or email in the top-right corner
  • Select "Account" from the dropdown
  • Your Account ID appears at the top of the Account Settings page

This is distinct from your Amazon.com retail account. The two exist on separate systems, even if you use the same email to log in.

4. Amazon Seller Account Identifier

If you sell on Amazon through Seller Central, your account has a Merchant Token (also called a Seller ID). This is a unique alphanumeric string that identifies your seller profile on the marketplace.

To find it:

  • Log into Seller Central
  • Go to Settings > Account Info
  • Look under "Business Information" — your Merchant Token is listed there

This identifier is used by Amazon's API, third-party integrations, and occasionally in customer-facing contexts.

Why the Context Matters 🔍

Knowing why you need an account number narrows down exactly which string of numbers or characters you're actually looking for.

Security Considerations Worth Knowing

Amazon support will never ask for your password over chat or email. If a form or message requests your "Amazon account number" in an unusual context, it's worth pausing. Legitimate Amazon interactions are typically initiated through your account dashboard or official app, not via unsolicited emails.

Your AWS Account ID, while not a password, can be used in targeted phishing attempts — so share it only in official AWS-related contexts.

Variables That Affect Where You'll Find It 🖥️

A few factors determine how straightforward this lookup is for you:

  • Account type — retail shopper, seller, AWS user, or Amazon Business account each have different interfaces
  • Device — the full account settings menu is more accessible via desktop browser than the mobile app
  • Account age and region — some older Amazon accounts or regional accounts (Amazon.co.uk, Amazon.de, etc.) may have slightly different menu structures
  • Whether your accounts are linked — Amazon Business accounts tied to personal accounts display additional identifiers

If you're accessing this from the mobile app, some settings menus are condensed or hidden behind additional taps compared to the desktop experience.

One Account, Multiple Identities

The underlying reality is that "Amazon account number" means different things depending on which layer of Amazon's ecosystem you're working in. 🛒 A retail shopper, an AWS developer, and an Amazon seller all have different identifiers — and even the same person operating in all three roles will have separate account IDs across those systems.

Whether the identifier you need is a 12-digit numeric code, an alphanumeric seller token, or simply the email address you signed up with depends entirely on what you're doing and which Amazon service is involved.
