One of the most common reasons Amazon rejects Brand Registry applications is a mismatch between the trademark and your listing details.
For approval, the brand name in your Amazon listings must exactly match the name on your trademark certificate like spacing, capitalization, and punctuation included. For example, “PureSkin” and “Pure Skin” would be treated as two separate entities.
Other possible reasons include:
Using a logo-based (design) mark but applying with a word-only name.
Trademark registered in a region not yet recognized by Amazon.
Trademark still under examination (not yet published or validated).
If you want to fix this issue, start by verifying your trademark’s registration number and wordmark format.
