How to Legally Add Tradelines to Your Credit Report

houseMatias Pintor Apr 25, 2025

Adding tradelines can be a smart, strategic way to improve your credit score—when done correctly. But let’s be honest: the tradeline industry has its fair share of bad players pushing inflated prices, sketchy tactics, or outright illegal schemes.

If you want to add tradelines legally, safely, and effectively, you need to understand how the process works—and more importantly, who you're working with.

That’s where we come in.

At Superior Tradelines, we’ve been helping people boost their credit the right way for over a decade. We’ve seen it all, and our mission is simple: deliver tradeline services that are honest, affordable, and grounded in real results—not smoke and mirrors.

This guide breaks down how to legally add tradelines to your credit report, what to watch out for, and how Superior Tradelines can help you do it right.

What Is a Tradeline?

A tradeline is any credit account that appears on your credit report—things like credit cards, mortgages, auto loans, and personal loans. Each one includes details like:

  • Lender name

  • Account type

  • Date opened

  • Credit limit or loan amount

  • Payment history

When people talk about “adding tradelines,” they usually mean becoming an authorized user on someone else’s seasoned credit card account. If that card has a strong history, you can benefit from it, even if you never use the card yourself.

Is It Legal to Add Tradelines?

Absolutely. Being added as an authorized user is completely legal and common practice. Parents do it all the time to help their kids start building credit.

What’s not legal? Using fake identities and falsifying information. There’s a clear difference between and fraud.

At Superior Tradelines, we’ve always played by the rules. We don’t make big promises, and we back up our guarantees. We take time to explain what tradelines can and can’t do, and we stay aligned with FTC guidelines. It's about long-term credit health, not quick fixes.

What Are Authorized-User Tradelines & How Do They Work?

Here’s the basic idea:

  1. You’re added as an authorized user to a credit card with a solid payment history.

  2. That account shows up on your credit report (usually within 15–30 days).

  3. The account’s age, limit, and payment history now contribute to your credit profile.

Even though you don’t use the card, it can help improve:

  • Credit age – Older accounts raise your average.

  • Utilization – High-limit, low-balance cards improve your credit utilization ratio.

  • Payment history – A perfect track record helps boost your score.

How to Add Tradelines to Your Credit Report

1. Know What You’re Trying to Accomplish

Are you recovering from a financial setback? Preparing to apply for a mortgage/loan? Trying to add to a thin credit file? Your goals will determine what kind of tradeline you need (e.g., older vs. newer, higher limits, etc.).

2. Pull Your Credit Reports

Get your reports from all three major bureaus: Experian, Equifax, and TransUnion. Look at:

  • Age of your accounts

  • Current utilization

  • Negative marks

  • Number of open accounts

This gives you (and us) a clear picture of where you stand and what kind of tradeline can help most.

3. Work With a Legitimate Company

This step is critical. Avoid middlemen and fly-by-night websites. You want to work with a company that:

  • Owns or directly manages the tradelines

  • Uses secure onboarding

  • Offers a written guarantee

  • Has real reviews and a track record

Superior Tradelines checks every one of those boxes. We’re not brokers—we manage our own inventory and control the process from start to finish.

4. Choose the Right Tradeline

Not all tradelines are equal. The best fit for you will depend on:

  • Age – Older tradelines generally carry more weight.

  • Limit – Higher limits help with credit utilization.

  • History – The payment record must be spotless.

We’ll help you match with tradelines that align with your credit profile and timeline.

5. Complete the Onboarding

We keep things simple and secure. You provide just the info needed to be added as an authorized user, and we do the rest. All Superior Tradelines information is handled through our secure and private portal.

6. Track Your Report

Once added, the tradeline usually appears on your report within 2–4 weeks. You can monitor progress through a credit app or by ordering updated reports.

If something doesn’t look right, our support team is here to help.

7. Use the Boost Strategically

Tradelines are typically temporary—they’ll post for one or two cycles (30–60 days). That gives you a window to:

  • Apply for credit

  • Refinance a loan

  • Lease a car or apartment

Used wisely, a short-term boost can lead to long-term opportunities.

Legal Risks to Avoid

A few red flags to watch out for:

  • Fake IDs or synthetic identities – Big legal trouble.

  • “Too good to be true” pricing – It usually is.

  • Unlicensed sellers – Many operate under the radar, with no safeguards.

  • Big promises about score increases – No one can guarantee points.

We don’t mess with shortcuts or shady tactics. We tell you what to expect and deliver exactly that.
