Amazon is tightening the rules around new ASIN creation — and if you're selling products tied to a Brand Registry-enrolled brand, the window to get your authorization in order is closing faster than you might think.

What's Actually Changing with ASIN Creation in June 2026

Starting in June 2026, creating a new ASIN for any brand enrolled in Amazon Brand Registry will require a verified reseller authorization — formal permission granted by the brand owner confirming you have the right to sell their products on Amazon. This isn't an entirely new concept, but the scope of enforcement is expanding significantly. Previously, restrictions like these applied in limited situations. Going forward, they look set to become a blanket requirement for Brand Registry brands across the board.

The practical implication: if you're a third-party reseller sourcing from distributors or wholesalers, simply having inventory on hand won't be enough. Without documented authorization from the brand itself, you won't be able to create new ASINs — full stop. Listing against an existing ASIN may still be possible in some cases, but new catalog contributions will be gated behind this authorization layer.

How Resellers Should Respond Before the Deadline

This change rewards sellers who have already built direct relationships with brand owners. If that's not you yet, here's where to focus your energy:

• Audit your current catalog — Identify which of your active or planned ASINs belong to Brand Registry-enrolled brands. Cross-reference against any existing authorization letters or agreements you hold.
• Contact brand owners proactively — Reach out to suppliers and brand contacts now to request formal reseller authorization documentation. Many brands have processes in place; getting in the queue early matters.
• Review your sourcing pipeline — If you rely on grey-market or multi-tier distribution channels where brand authorization is murky, this is a signal to reassess. Products you can't get authorized for may become impossible to list newly after June 2026.
• Check Seller Central for official guidance — Amazon's full policy language will be the authoritative source. Monitor your account health dashboard and policy update notifications closely.

The Bigger Picture: Amazon Is Accelerating Brand Control

This move is part of a longer trend. Amazon has been systematically strengthening Brand Registry's value proposition for brand owners — giving them more tools to control who sells their products and how. For legitimate authorized resellers, that's actually good news: less unauthorized competition, cleaner Buy Box dynamics, and a more level playing field. For sellers who've operated in gray areas, the squeeze is real.

The sellers who will feel the most disruption are those who rely on catalog creation as a workaround — adding slight variations or creating new ASINs to get around listing restrictions. That playbook is being shut down. Sellers who invest in formal brand partnerships now are building a more durable business on Amazon regardless of how enforcement evolves.

Bottom line: reseller authorization is becoming table stakes for selling branded products on Amazon. Treat June 2026 not as a deadline to scramble toward, but as a forcing function to build the brand relationships your business should have had all along.

FAQ

Reseller authorizationはどこで取得できますか？

Amazon経由で付与されるのではなく、ブランドオーナー（メーカーや正規代理店）から直接取得するものです。ブランドによって書面での許可書、メールでの確認、またはAmazonの「Selling Application」プログラムを通じた承認など形式はさまざまです。まず仕入れ先または当該ブランドの公式連絡窓口に問い合わせましょう。

既存の出品（既存ASIN）への相乗りにも影響しますか？

現時点での情報によると、今回の変更は主に「新規ASIN作成」に関するものです。既存ASINへの相乗り出品への直接的な影響は明確になっていませんが、Amazonのブランド保護ポリシー全体が強化傾向にあるため、Seller Centralの公式アナウンスを継続的に確認することを推奨します。
