Thank you for sharing your experience!

Here’s what to keep in mind as you work through this:

Walmart Brand Portal only accepts trademarks registered with the United States Patent and Trademark Office (USPTO). Pending trademarks are not sufficient for brand registration. If your trademark is still pending, you cannot complete brand registration as a brand owner. You may need to wait until your trademark is fully registered and has an active status with a seven-digit registration number.

For faster registration, follow USPTO guidelines and ensure all documentation requested by Walmart is accurate and submitted promptly. For more details on the aforementioned topic, review this guide - Brand portal: Register your brand.

Not sure you can register until trademark issued
