Wife is the primary member, I am the add on. Tried to register my own account on the app but apparently we don’t have the same membership number. So where can I find mine?

Just a tidbit of information I wanted to share - I just recently signed up for Sam's Club and added my spouse as a complementary household member.

It seems a bit ridiculous that they don't tell the household member their own ID number in the welcome email so that they can register and use the website/app. I was googling and found some places recommended getting physical cards first or going through chat to find the ID number for the extra members.

What I was able to do is, as the primary account member, go to the Account -> Additional Cardholders section of the website. I opened Developer Tools from the menu in my web browser and found the request with a URL ending in /v3/membership/summary. Viewing the response payload for that request will show the complementary member's membership ID which in my case is very very similar to the primary ID but with a digit changed.

Hi! Desperately looking for help here lol. Not sure if I can post this here but I don't see anything against it in the rules I think.

So I'm not a Sam's Club member, but I work for an insurance brokerage, we work with Mercury Insurance and they have a discount for having a Sam's membership, to apply this discount they ask for proof of membership in the form of a screenshot of your membership details (needs to show name, membership number and expiration date). They also have one for Costco and AAA, for AAA a photo of the physical card is fine and for Costco they sent us a step by step guide to send to customers but they don't have one for Sam's for some reason. If anyone knows how to view this that would be so much help, our clients are mostly older Spanish speaking folks so this is kind of confusing for them too.

I dont know how many clubs do this but there has to be a better way than digging through my wallet for my membership card. It would be easier to pull up the app on my phone to display my membership status.
