Authorized User Tradelines Guiding Principles Tradelines with Gamba, one of the best tradeline companies will add you as an Authorized User (AU) to credit cards, sometimes known as tradelines, with perfect credit history, high limit and low balance for two statement cycles (approx 60 days).

The history of the cards are then added into your credit history and a new credit score is calculated. Tradelines are kept with a utilization of 10% or less which is ideal.

When selecting a tradeline, always select a tradeline from a bank you have never had any history with. Keep in mind that while tradelines can be very helpful, they don’t work for every type of credit report.

For example, if your report has recent collections, charge offs or late payments, it is highly likely that tradelines will not be a good fit for your credit. We highly recommend booking a consultation.

The cost of the consultation goes towards your initial purchase. You can do so by going to the Book a Consultation page.
