In general lenders only allow authorized user accounts to report to the credit report only when the account is live and active for the user. This means when buying authorized users from a vendor like us there is a very high probability that the reporting will cease after about 1-2 months.
The main reason this happens is because the vendor has a limited number a “slots” available of the credit card and those slots have to be reassigned to the next user. If you are seeking a more permanent or long term solutions you should consider getting an authorized user from a friend or family member.
