A temporary or disposable phone number used to satisfy the phone number verification requirement during the Instagram account creation or login process. These numbers are typically obtained from online services and are not intended for long-term use or permanent association with an account. As an illustration, an individual might use such a service to bypass providing a personal phone number when setting up an additional Instagram profile.
The perceived advantage lies in preserving personal privacy by avoiding the association of a personal phone number with an online account. This practice has become prevalent due to growing concerns about data security and unwanted contact. However, the use of such services also carries potential risks, including possible account suspension by Instagram due to violations of their terms of service.
