Hello GudmundsonC Webster,
I'm not sure what you want. Here is some information that I found,
Public Instructions: If you are a member of The Church of Jesus Christ of Latter-day Saints, you can find your Church record number in several places:
You can ask the Ward Clerk about your Membership information.
Other questions can be answered by going to FamilySearch.org, when signed in your name is on the upper right. Just to the left of your name is a ? question mark. Click on the question mark and in the dropdown box, click on Help Center, then type your question about Ward Clerk Membership. There will be a list of answers. I hope one of them will help you.
Is this a help? I hope so.
And if all you are looking for is your membership number, after signing in to FamilySearch.org, go to your name in the top right of the window and select "settings". Go to the Account tab and your membership Record Number is towards the bottom of the page.
If you have a temple recommend, it will be on that as well.
