Followed the instructions on:
Note the following : Marriott Rewards was a bit difficult due to the fact that most pages didn't show my full name AND my rewards number. You may need to send multiple screenshots to fulfill the satisfactory that all documents show:
• Your full name
• Your full Marriott Rewards Account #
• The specific name of the programme "Marriott Rewards"
I ended up sending three documents:
• A screenshot of the top of the Marriott Rewards Member Overview
• An extended screenshot of everything underneath it
• The last hotel bill I can retrieve from my account via Marriott.com
I got matched a day later.
