" I'm not sure how to proceed right now and also don't know the true reason it could be."

Amazon is a graduate level course in reading between the lines.

Here are some of the most common issues with BR.

Go over everything with a magnifying glass looking for a missing 'period' or 'comma'.

Is there a different capitalization, abbreviation, spelling, or, even an extra spa ce?

Is your Brand registered (or applied for) with the USPTO?

Amazon is admitting applicants under CERTAIN conditions when only filed but not granted.

This is from Sandy_Amazon on 5/16/2023

“To be eligible for Amazon Brand Registry, your brand must have an active registered trademark in each country where you wish to enroll or have a pending trademark application filed through Amazon IP Accelerator. Brand Registry is also accepting brands that have a trademark pending registration in a subset of trademark offices.”

Additionally, IF you ever get an actual TM (if you don’t now) When Amazon says something must match they mean EXACTLY!

That means Street is not ST.

Jim is not James.

ALL CAPS is not SOme CAps

Thanks to Sandy_Amazon for letting us all know that applications are also space sensitive.

And so on………………..

They mean every comma, period, dash, etc. must be EXACTLY THE SAME INCLUDING SPACE S.

Go over everything with a magnifying glass looking for a missing 'period' or 'comma'. Is there a different capitalization, abbreviation, spelling, or, even an extra spa ce?

What is the EXACT BRAND (as GRANTED) on the USPTO site? Is it the EXACT same as the Brand on the Amazon account AND the brand on the packaging?

What is the name of the Owner (REGISTRANT) on the USPTO site? Is it the EXACT same name as the owner of the Amazon account?

If it is NOT exactly the same you will need to show some proof that the two are the same as to ownership! Because I manufacture under one LLC and sell under a different one, I had to submit my LLC State Registration with MY name as the owner of the LLCs showing the common ownership.

The OWNER of the Brand is the one that MUST enter into the Brand Registry agreement. If the owner is not the same as the Amazon seller the seller will have to be granted access by the owner AFTER REGISTRATION.

You might have to take a picture of it while holding it in your hand (unless it weighs 1000 pounds!)

Amazon can be 'weird' at times and I have seen where they ask for a handheld picture.

In addition, on one post @jim_amazon added this interesting reason for a rejection!

“One other piece of advice, I've some applications have issues when the 'Suggested ASINs' list is filled out incorrectly so I recommend leaving that section blank!”

Additional comment from @dougal_amazon on rejections --

“In the interim, @NEVERLAST is spot on with making sure your application matches with USPTO exactly. The 2 areas I see the most common errors (for US TMs) are the Trademark type not aligning with the what can be accepted for enrollment. You can check this out on the Enrollment guidelines for the US help page. Or, the current owner information tab in USPTO does not align with what you have submitted for you application, to include any attachments. “
