Dropbox Referral Codes

To use your Dropbox referral code or link, click the referral link during signup at https://dropbox.com, which will automatically apply the code to your account and qualify you for any associated benefits. Alternatively, if you have a referral code instead of a link, you can enter it during the account creation process in the "Promo code" or "Referral code" field on the signup page. Dropbox typically uses referral links rather than short codes, so using the direct link from your referrer is the easiest method.
