Twitter has been known to be a quick and easy way to communicate with friends and family, but it can also be a bit of a mystery as to how long it takes for the company to unlock an account for someone who is older than 18. According to Twitter, it typically takes around two business days for an account to be unlocked for someone who is older than 18. However, this time frame may vary depending on the individual’s location and activity history. Twitter also states that if an account is locked because of age or other reasons, it can still be unlocked by contacting Twitter support. In order to do so, you will need to provide your name, email address and phone number.
