Overview

When creating a new ASIN on Amazon, sellers may encounter error codes 5664, 5665, or 5668 — all related to brand name approval. These errors prevent you from listing products until you either get your brand name approved or correctly assign a brand value. Understanding the specific requirements for each error code and how to resolve them can save you significant time and frustration.

Key Points / What Sellers Need to Know

• Brand names require approval before use — Amazon must approve your brand name before you can create ASINs associated with it. Attempting to list without approval triggers blocking errors.
• Spelling and formatting matter — Brand names are case sensitive, and even minor differences in spacing or characters will cause rejections. Double-check that the name matches exactly what you want displayed on the detail page.
• Approval is global — Once Amazon approves a brand name, it applies across all countries. There is no need to submit separate applications for each marketplace.
• Processing takes up to 24 hours — After approval, allow up to a full day before attempting to create listings with the new brand name.
• Generic products need "generic" as the brand value — Unbranded products without a distinctive name or logo must use "generic" as the brand field value.
• Product images must be real photographs — Computer-generated images, blurry photos, or digitally altered pictures will result in your application being declined.

Understanding the Three Error Codes

Error 5664 indicates that you may be listing a branded product without following the proper brand name policy, or listing a generic product without using "generic" as the brand name. To resolve this, recreate the error by attempting to add the product again, then follow the instructions in the error message. You will need to submit an application with the exact brand name as you want it displayed, a logo image, and at least two real-world product images showing the brand permanently affixed to the product or packaging.

Error 5665 means that the brand name you entered has not yet been approved by Amazon. You must submit a brand name approval application with the required documentation before you can proceed with listing. If you have already received approval but the error persists after 24 hours, contact Amazon Seller Support for assistance.
