You can verify the total number of notes, notebooks, tags, and attachments directly in your account. Just open the corresponding section (e.g., open the Note list to check the total number of notes, or open Files to see the number of attachments) and check the number displayed at the top of the list.
Note: Notes in the Trash also count towards the overall note limit.
Currently, there is no section to check to total storage used, but we're working to add it soon. We apologize for the inconvenience and thank you for your patience as we work to improve your experience.
If you want to check how much storage Evernote is taking up on your desktop device instead, visit this article.
