Instagram’s account creation process requires a unique email address for each account. This requirement prevents multiple accounts from being directly linked to the same email within the platform’s native registration system. Attempting to register multiple accounts with the same email will result in an error, indicating that the email is already in use.
This restriction is in place to maintain account security and prevent spam or abuse on the platform. It also allows Instagram to accurately identify and manage its user base, ensuring that each account is associated with a distinct individual or entity. Historically, this policy has been a consistent element of Instagram’s approach to account management, promoting a degree of separation and control over user profiles.
