What is instagram handle?

Instagram handle
The unique @username that identifies an Instagram account and forms its URL.
A handle is the account's identity for tagging, mentions, and links, instagram.com/nike is @nike. Display names are not unique and change freely; handles are unique and change rarely, which is why every monitoring system keys off the handle.
A brand that operates regional accounts (@nike, @nikefootball) fragments its mention volume across them, so a competitive analysis has to decide up front which handles constitute the brand.
