Instagram Page Verification steps are here direct from Instagram.
Have you ever wondered how to verify your Instagram page? Instagram, in an effort for transparency has made it easier to attempt to verify your page and receive the coveted check mark next to your page name. This will only work if your page is a business page and will not work if the page is a personal page. So first, make sure your page is converted to a business page.
Follow the steps below screen by screen and you should be all set to attempt to verify your page. We use the wording attempt because at the end of the day it is still up to Instagram for them to approve your request.
