You must not use domain names or web URLs in your username without prior written consent from Instagram.
Instagram usernames are assigned on a first–come, first-served basis. We require a national or community trademark registration in order to consider requests for username transfers.
If you have a national or community trademark registration, please reply to this email with the registration number, a digital copy of the registration, or a link to the trademark registration on the appropriate intellectual property office’s website, and we will be happy to look into your request.
