Hello Sellers,
If you've tried to create a new listing and hit an error code starting with 5, you're not alone. Errors 5461, 5664, 5665, and 5668 are among the most common listing creation blocks on Amazon — and they all relate to catalogue authorisation, Amazon's system for ensuring brand data entering the catalogue is accurate and comes from qualified sellers.
Here's what each error means, why you're seeing it, and what to do next.
Error 5461 — Brand Match Only
This error appears when you try to create a new ASIN for a brand that's enrolled in Amazon's Match Only protection. It means the brand's catalogue is considered complete, and new ASIN creation is restricted to brand owners, authorised resellers, and pre-approved sellers.
Why it happens: The brand has verified its full product range is already listed. Amazon restricts new ASIN creation to prevent duplicates and unrelated products appearing under that brand.
What to do:
- Submit an application directly from the error message — you'll need your product ID (UPC/EAN), brand name, product title, description, category, manufacturer name, and real-world images of the product and packaging showing the brand name and barcode
- If you believe the product genuinely doesn't exist in the catalogue, your application will be reviewed by the catalogue authorisation team
- Approval is temporary (48–96 hours), so be ready to create your listing promptly once approved

Errors 5664 and 5665 — Brand Name Authorisation
These errors appear when you attempt to list a product under a brand name that either doesn't exist in Amazon's catalogue yet or doesn't match the exact authorised spelling.
Why it happens: Amazon requires every brand name to be reviewed and approved before it can be used in listings. This prevents fraudulent or infringing brand strings from entering the catalogue. If your brand is already authorised, even small variations — trailing spaces, missing apostrophes, or slight misspellings — will trigger the block.
Example: If "Philomena's Jewellery" is the authorised brand name, attempting to list under "Philomenas Jewellery" or "Philomena's Jewelry" will be rejected. Capitalisation differences are the only exception.
What to do:
- Double-check the exact brand name spelling in your Brand Registry profile or previous successful listings
- If the brand is new to Amazon, submit the Brand Name Approval form linked in the error message with real-world product images showing branding permanently affixed to the product or packaging
- If your brand has a registered or pending trademark, consider enrolling in Amazon Brand Registry for a smoother path

Error 5668 — Null Brand
This error appears when you try to list a product without specifying any brand name at all, or when the brand field contains an invalid value.
Why it happens: Every product on Amazon must have a valid brand attribute — either a recognised brand name or "Generic" for unbranded products. Leaving the field blank or using placeholder text like "N/A" or "No Brand" will trigger this block.
What to do:
- If your product belongs to a brand, enter the exact authorised brand name
- If your product is genuinely unbranded, use the value Generic in the brand attribute field
- Ensure you're not using descriptive text (e.g., "Phone Cases" or "Kitchen Tools") as a brand name — these will be rejected
Common Mistakes Across All Four Errors
- Using a product description as a brand name — "Wireless Earbuds" is not a brand
- Submitting digitally altered images — product photos must be real-world, hand-held or placed on a surface
- Mismatched brand spelling — the brand name in your listing must exactly match the authorised version
- Expired or missing product IDs — ensure your UPC/EAN is valid and registered with GS1
