Tradelines Selected for Reliability and Clear Reporting
An authorized user tradeline is a seasoned credit card account that you are added to as an authorized user. The account's age, credit limit, and perfect payment history then appear on your credit report — typically within one billing cycle (15–30 days). This can increase your credit score by improving your average account age, lowering your overall utilization ratio, and adding positive payment history. OptimizeCredit.net guarantees reporting to at least 2 of 3 major bureaus or provides a full refund. With 500+ successful placements and 3 reporting cycles included per tradeline, it is one of the fastest ways to build credit for mortgage approvals, auto loans, apartment applications, and other financing needs.

Clear answers on reporting, timing, score expectations, and our refund policy.
What is your reporting guarantee?
We guarantee that your purchased tradeline will report to at least 2 of the 3 major credit bureaus, or we will provide a full refund.
Before issuing any refund, we first troubleshoot the reporting issue. In many cases, delays happen because the name or address submitted does not match the way your credit profile appears at the bureaus, and this can often be corrected.
To complete this review, we may ask you for your latest credit report or screenshots from your monitoring site so we can verify whether the tradeline has already reported, whether the bureau is still updating, or whether a profile-matching issue needs to be corrected first.
Why can reporting timing vary slightly?
The reporting windows shown in the table are based on normal timing, but the exact date can vary slightly depending on the bureau and the monitoring tool you use.
It is common for one bureau or one monitoring platform to show the update before another. This is normal and does not mean there is a problem.
Will this tradeline increase my score?
While we cannot guarantee a specific number of points, the right tradeline is designed to strengthen the right credit profile and often leads to meaningful score improvement.
Results are usually strongest when your score is not already above 750, and when you choose a tradeline that fits your current profile needs — such as account age, credit limit, or reporting timing.

How quickly will I be added to the tradeline?
In most cases, we place the authorized user add within 1–3 days, and often sooner.
How long does your service stay on for reporting?
Our service includes 3 reporting cycles on every tradeline.
Many other services only provide 2 cycles. We provide 3 to give you enough time to make important financing or life changes, while also supporting better account stability.
What information do you need from me?
Most tradelines require your full legal name, date of birth, and current address. Some tradelines may also require SSN — this is clearly shown in the table before purchase.
