About AMZDOC

Meet the Founder

Igor Kostenko — Founder & Lead Consultant

I founded AMZDOC in 2019 with a clear mission: to help Amazon sellers solve their most challenging account problems through legitimate, professional methods.

Since then, I have personally handled hundreds of cases across ungating, account reinstatements, complaint resolutions, and identity verifications. This is not just a business for me — it is my craft. I am deeply passionate about what I do, and I am continuously expanding my expertise to stay ahead of Amazon’s evolving policies and processes.

What sets AMZDOC apart is that I personally oversee every case. As the owner and lead consultant, I maintain direct involvement in each project from start to finish. Your case is never handed off to an inexperienced team member — you get the benefit of years of accumulated expertise and a founder who genuinely cares about the outcome.

      My approach: Every seller’s situation is unique. I take the time to understand the specific details of your case, identify the real root cause, and develop a tailored strategy — not a generic template. I treat every case as if it were my own business on the line.
    

About AMZDOC LLC

AMZDOC LLC is a professional Amazon seller consulting firm registered in Sacramento, California. Since 2019, we have been helping Amazon sellers across the United States and internationally navigate the most complex account challenges on the platform.

Our expertise spans the full range of Amazon Seller Central issues — from brand ungating and restricted category approvals to suspension appeals, Plan of Action writing, complaint resolution, and identity verification.

What We Specialize In

Account Reinstatement

Suspended for inauthentic items, policy violations, or performance issues? We craft effective Plans of Action and appeals based on years of experience with Amazon’s Seller Performance team.

Brand & Category Ungating

We help sellers gain approval to sell restricted brands and categories through proper documentation, established supplier relationships, and correct application procedures.

Complaint Resolution

Intellectual property complaints, authenticity claims, and product condition issues — we help identify the source, address the underlying problem, and respond effectively.

Identity & Compliance Verification

P-4 verification, INFORM Act compliance, and other Amazon identity checks — we guide you through the documentation requirements to pass on the first attempt.
