Why is Instagram asking for my birthday?
You must be at least 13 years old to have an Instagram account in most countries. If you discover an account that belongs to someone under the age of 13 years old, please report it. We ask for birthday information to help ensure that underage people aren’t using Instagram. This includes everyone, whether the Instagram account represents you personally, or if the account was created for something else (example: accounts dedicated to a pet, hobby, or brand).
This information also helps us provide age-appropriate and safer experiences for the youngest members of the Instagram community. For example, we won’t display alcohol-related ads to people who are under the legal age limit in their country.
