Please correct me if I am wrong, your MongoDB Atlas deployment used AWS as cloud provider and while using their infrastructure, I believe those numbers are AWS designation used by Atlas internally, thus those numbers are a part of the automation information used by Atlas to manage your deployment.
Is there an issue that you’re facing that you have traced to the use of those numbers?
There was an request to report who is the owner id(which turns out to be ATLAS internal number) from internal security audit in my company. That owner id isn’t one of our maintained aws account list, so that’s why I asked about it.
Thank you for your help!
