How to Find Your Amazon ID: A Comprehensive Guide for Sellers, Associates, and Customers

To find your Amazon ID, you must first identify which specific identifier you need. For sellers, the Merchant Token is located under Settings > Account Info in Seller Central. For associates, the Store ID is visible in the top right of the Associates Central dashboard. Customers can find their Account ID within their profile URL or through personalized data requests.

Because Amazon operates as a massive ecosystem involving retail shoppers, third-party merchants, and affiliate marketers, the term "Amazon ID" is inherently ambiguous. Depending on your role within the platform, you might be looking for a Merchant ID to integrate a third-party tool, a Tracking ID to monitor affiliate commissions, or an ASIN to identify a specific product.

As of 2026, Amazon has further streamlined its dashboards, but the core locations for these identifiers remain consistent. This guide provides detailed, step-by-step instructions for locating every major type of Amazon identifier across all primary user categories.

Identifying the Different Types of Amazon IDs

Before navigating through menus, it is essential to distinguish between the various strings of numbers and letters Amazon uses for identification. Using the wrong ID can lead to failed API integrations, lost affiliate revenue, or confusion during customer support interactions.

1. Merchant ID (Seller ID): A unique alphanumeric string assigned to a professional or individual seller account. It is required for connecting software like inventory managers, repricers, or tax tools via the Amazon Selling Partner API (SP-API).
2. Associate ID (Store ID): A public-facing identifier used by affiliate marketers (Associates). It typically ends in a suffix like "-20" or "-21" and is embedded in links to track referrals.
3. Customer Account ID: An internal identifier for individual shopping accounts. While rarely needed for basic shopping, it is occasionally required for advanced account recovery or specific developer-level integrations.
4. Amazon Standard Identification Number (ASIN): A 10-character alphanumeric unique identifier assigned by Amazon.com and its partners for product identification within the Amazon organization.
5. Order ID: A 17-digit number formatted as 000-0000000-0000000 used to track specific purchases.

How to Find Your Amazon Seller Merchant ID

For third-party merchants, the Merchant ID (often referred to as the Merchant Token) is the most critical identifier. It serves as your unique fingerprint in the Amazon marketplace. In 2026, Amazon continues to require this token for any secure handshake between your Seller Central account and external service providers.

Step-by-Step Location in Seller Central

To find your Merchant Token, follow these precise steps:

1. Log in to Seller Central: Ensure you are logged in with an account that has administrative permissions.
2. Navigate to Settings: In the top-right corner of the dashboard, hover over the gear icon (Settings).
3. Select Account Info: From the dropdown menu, click on "Account Info." This page contains the "Seller Account Information" overview.
4. Locate Business Information: Look for the section titled "Business Information."
5. Click on Merchant Token: Inside this section, you will see a link for "Merchant Token." Clicking this will display your unique ID.

Why the Merchant Token is Essential

The Merchant Token is not just a label; it is a security credential. When you authorize a third-party application to access your data—such as Helium 10, Jungle Scout, or various ERP systems—they require this ID to identify which data stream to pull from the Selling Partner API. Unlike a password, the Merchant Token stays constant even if you change your login credentials. However, you should never share this token publicly, as it is a key component of your business's technical identity on the platform.

Locating Your Amazon Associate ID and Tracking ID

Affiliate marketers rely on the Amazon Associates program to generate income. To ensure clicks are credited to your account, your Associate ID must be present in every URL you share.

Finding the Primary Store ID

The Store ID is your main account identifier. You can find it by:

1. Logging into the Amazon Associates Central portal.
2. Looking at the very top-right corner of the screen.
3. Your ID will be clearly displayed (e.g., mywebsite-20).

Managing Multiple Tracking IDs

Many associates use different Tracking IDs to compare the performance of different websites, social media channels, or specific ad campaigns. To find or create these:

1. Hover over your email address in the top right of the Associates Central dashboard.
2. Select "Manage Your Tracking IDs" from the dropdown.
3. Here, you can see a list of all active IDs or create new ones to segment your data.

It is a common mistake to use the main Store ID for everything. By creating unique Tracking IDs, you gain granular insights into which content is actually driving conversions. In 2026, data-driven marketing is more competitive than ever, making the correct use of these IDs vital for optimizing your ROI.

How to Find an Amazon Customer ID

The average shopper rarely needs to know their internal "Customer ID." However, if you are a developer testing an integration or a user attempting to resolve a complex account synchronization issue, you may need to find it.

Method 1: Using the Profile URL

The most direct way to find your public-facing customer ID is through your Amazon Profile:

1. Go to the Amazon homepage and ensure you are logged in.
2. Hover over "Account & Lists" and click on "Your Account."
3. Scroll down to the "Ordering and shopping preferences" section and click on "Your Amazon profile."
4. Look at the URL in your browser’s address bar. It will look something like this: amazon.com/gp/profile/amzn1.account.ABC123DEF456...
5. The string starting with amzn1.account. is your unique Amazon Customer ID.

Method 2: Requesting Your Data

Under various privacy laws, Amazon provides a way for users to download their entire data history. This file contains every internal identifier associated with your account. You can request this by navigating to the "Request Your Data" page under the "Privacy" section of your account settings. While comprehensive, this method can take several days to process.

Finding Product IDs (ASIN) and Order IDs

Beyond account-level identifiers, users frequently need to find IDs related to specific items or transactions.

Locating the ASIN

The ASIN is the "social security number" for products on Amazon. Every product variation (size, color) has its own ASIN. You can find it in two places:

1. The Product URL: In the browser address bar, the ASIN is the 10-character string following /dp/. For example, in amazon.com/Product-Name/dp/B00X4WHP5E/, the ASIN is B00X4WHP5E.
2. Product Information Table: Scroll down the product page to the "Product Information" or "Technical Details" section. The ASIN will be listed alongside dimensions and weight.

Locating the Order ID

If you need to return an item or contact a seller about a specific purchase, you need the Order ID.

1. Go to "Returns & Orders."
2. Find the relevant purchase.
3. The Order ID is displayed in the top-right corner of the specific order box.

Common Troubleshooting Steps

If you are having trouble finding or using your Amazon ID, consider these common issues:

• Permissions Issues: If you are an employee using a sub-account in Seller Central, you may not have permission to view the "Account Info" page. You must ask the primary account owner to grant you "Manage Your Accounts" permissions.
• Marketplace Variations: Amazon IDs are often marketplace-specific. Your Merchant Token for the North American marketplace (US, CA, MX) may differ from your ID in European marketplaces (UK, DE, FR). Always ensure you are logged into the correct country-specific dashboard.
• Browser Cache: Sometimes, the "Merchant Token" page fails to load the alphanumeric string. If you see a blank space, try clearing your browser cache or opening Seller Central in an Incognito/Private window.
• Identity Verification: For newer accounts in 2026, Amazon may require secondary biometric or SMS verification before displaying sensitive information like the Merchant Token.

Security Considerations for Your Amazon IDs

While an ASIN or an Order ID is relatively safe to share in the context of support or reviews, your Merchant Token and Customer ID should be handled with care.

1. Avoid Public Forums: Never post your Merchant Token or internal Customer ID on public seller forums or social media groups. Malicious actors can use these identifiers to target your account for "black hat" tactics or phishing attempts.
2. Third-Party Access: Only provide your Merchant ID to reputable, verified third-party applications. Always check the Amazon Seller Central Partner Network to ensure the software you are using is officially recognized by Amazon.
3. Revoking Permissions: If you stop using a third-party tool, don't just cancel the subscription. Go to your Seller Central settings under "User Permissions" and "Third-party developer and apps" to formally revoke their access.

FAQ: Frequently Asked Questions about Amazon IDs

Is my Amazon ID the same as my email address?

No. Your Amazon ID is a unique alphanumeric string generated by Amazon's internal systems. While you use your email address to log in, the ID is used by Amazon's database to track your business or shopping activity independently of your login credentials.

Can I change my Amazon Merchant ID?

No, the Merchant ID (Merchant Token) is permanently assigned to your seller account upon creation. Even if you change your business name, legal entity, or contact information, the Merchant Token remains the same. If you require a different Merchant ID, you would typically need to close your current account and open a new one, which is subject to Amazon's strict "one account per seller" policy.

How do I find my Amazon Vendor ID?

If you are a first-party vendor (selling to Amazon, not on Amazon), your Vendor ID is located in Vendor Central. Go to Settings > Account Settings > Business Information. Your Vendor Code (usually a 4-5 letter code) serves as your primary identifier.

Where is the Amazon ID on the mobile app?

On the Amazon shopping app, you can find your Order IDs under "Your Orders." To find your Customer ID, go to your Profile (the person icon), click "Your Profile," and share your profile link to see the ID in the URL. For Sellers, it is highly recommended to use a desktop browser to find the Merchant Token, as the Amazon Seller app often hides deep technical settings.

Does every product have an ASIN?

Almost every product on Amazon has an ASIN, with the notable exception of books. For books, Amazon uses the ISBN-10 (International Standard Book Number) as the identifier. For all other categories, once a product is listed, an ASIN is automatically generated.

Next Steps for Sellers and Associates

Once you have located the correct Amazon ID, your next action depends on your goal. If you are a seller, you should securely store your Merchant Token in your business records for future integrations. If you are an associate, ensure your Store ID is correctly implemented in your "SiteStrip" settings to make link generation seamless.

For those integrating with the Selling Partner API, remember that in 2026, Amazon requires rotating security tokens alongside your Merchant ID. Ensure your developer credentials are up to date and that you are following the latest security protocols to prevent service interruptions.
