What is Your Preferred Associates Store ID in Amazon?

When I created my Amazon Associates account for the first time, I stumbled on a field that asked for my “Preferred Associates Store ID.” I paused for a moment to understand exactly what this was.

Do I need to come up with a perfect name right now? Can I change this later? Will this affect my earnings?

If you’ve had the same questions, you’re not alone. This little setup often confuses new affiliates, but the thing is, it’s one of the simplest parts of setting up your account.

Your store ID is basically your affiliate identity, the tag Amazon uses to track your sales and reward you with commissions.

In this blog, I’ll walk you through what your Preferred Associates Store ID is, why it matters, and how you can choose the right one without stressing too much.

What is a preferred associates store ID​ in Amazon?

When you’re applying to join the Amazon Associates Program, and the “complete your profile” section asks you to enter your store ID, the first question that arises in your mind is, “What is a preferred associated store ID?

Your preferred associates store ID is like your username in the Amazon affiliate world. It’s a unique identifier Amazon uses to know that “you sent this customer, so you get the commission.”

I remember when I first saw this field, I thought it was going to be some complicated technical thing. But it’s just a name tag for your affiliate business.

When someone clicks your affiliate link and buys something on Amazon, your preferred associates store ID tells Amazon’s system, “Give this commission to Sarah,” or whoever you are.

Without this ID, Amazon cannot determine who deserves credit for the sale.

Your Amazon preferred associates store ID is essentially your business name within the Amazon ecosystem. It appears in your affiliate links and serves as your tracking code across all Amazon marketplaces where you’re approved.

The store ID typically follows a simple format: your chosen name plus a number and country code. For example, if you choose “techreviews” as your preferred name, your full associates store ID in Amazon might look like “techreviews-20” for the US marketplace.

Amazon preferred associates store ID: country-specific ID suffixes

When you input your preferred associated store ID in Amazon, you’ll see that it ends with a number. For example, mostly -20 or -21.

It’s because Amazon has separate programs for different countries, and each one has its own little code at the end of your ID.

In the US, your Amazon preferred associates store ID gets a “-20” stuck on the end. So if you choose “coffeelover,” you end up with “coffeelover-20” as your complete ID.

Similarly, if you want to promote products in the UK, you’ll end up with “-21,” and so does Germany.

Here is a short list of Amazon Associates Tracking ID suffixes by region:

• United States → -20
• Canada → -20 (same as US, but separate program)
• United Kingdom → -21
• Germany → -21
• France → -21
• Italy → -21
• Spain → -21
• Netherlands → -21
• Sweden → -21
• Poland → -21
• Egypt → -21
• Japan → -22
• India → -21
• Brazil → -20
• Mexico → -20
• Australia → -21
• Singapore → -21
• Saudi Arabia → -21
• UAE (United Arab Emirates) → -21
• Turkey → -21

It may seem random, but that’s just how Amazon organized its system.

You can’t just use your US store ID in other countries. You need to apply separately for each Amazon program you want to join.

But you can usually pick similar names, so if “coffeelover-20” works in the US, you might get “coffeelover-21” in the UK and “coffeelover-22” in Japan.

Best practices for choosing a preferred associates store ID

Let me share some lessons I’ve learned, along with tips from other affiliates, over the years. Here are some things you should keep in mind while choosing your preferred associates store ID for Amazon.

Don’t overthink it, but don’t underthink it either. Keep it related to your niche/site.

• If your site is about tech gadgets → techgadgets-20.
• If it’s about fitness gear → fitnesshub-20.
• If you’re doing kitchen reviews → kitchenstuff-20 makes more sense than “johnsmith123.”

Make it something you can live with. Make it short & easy to remember.

• Avoid long or confusing names that you’ll hate typing later.
• Good: homedeals-20.
• Bad: allthebesthomedecorproductreviews-20.

Skip the personal name route.

I see newbies use their full names all the time. While Amazon allows it, your links end up looking like “amazon.com/dp/B08XYZ?tag=johnsmith-20” which doesn’t scream “professional affiliate” to me.

Keep it simple. Avoid complicated combinations of numbers and letters.

• Stick to letters only. No spaces, underscores, or symbols.
• Good: outdoorlife-20.
• Bad: outdoor_life-20 or outdoor-life!-20.

Choose a brand-friendly approach.

• If you already have a website, just use the domain name as your preferred associates store ID.
• Example: For a site called “GearBuzz,” → gearbuzz-20.
• For “Travel Smart” → travelsmart-20.

Avoid trademark trouble

• Don’t use Nike, Apple, or any brand names in your ID.
• Amazon may overlook it at first, but it could create issues for you in the future.

Think about the long game and future-proof your choice.

• Don’t limit your choice to a tiny niche if you plan to expand.
• Instead of gamingmouse-20, choose gamingdeals-20.
• Instead of yogamats-20, go with fitnessgear-20.

One last thing, say it out loud. If you can’t easily tell someone your store ID over the phone without spelling it out letter by letter, maybe pick something else.
