The domains that Dropbox uses in an official capacity

Dropbox uses several domains to run the service. Each domain serves a specific purpose, like running the Dropbox product, providing communications, or hosting marketing materials. Check the domains in this article if you’re unsure if it’s safe to go to a particular website or accept a communication from an email address that looks like it's from Dropbox.

Sections in this article:

dropbox.com and paper.dropbox.com

Most of the things you can do with Dropbox online happen on dropbox.com and paper.dropbox.com. dropbox.com is the only domain where Dropbox will ever ask for private information like the email address and password for your Dropbox account. Be wary of any other domains that look like Dropbox that ask you for your Dropbox email or password.
