Every day, thousands of sneakers, handbags, and collectibles pass through CheckCheck. To you, it’s a simple upload. To us, it’s a meticulous process designed to protect buyers and sellers from the ever-growing world of counterfeits.
Here’s what really happens behind the check and why every detail matters.
Step 1 – Your Photos Tell the Story
It all starts with your photos. When you submit an item, you’re giving our experts the clues they need to authenticate it.
- Sneakers: We review everything from toe box shape to stitching patterns, heel tabs, and even insole details.
- Handbags: Our team examines glazing, stitching, logo placement, serial codes, and hardware finishes.
- Collectibles: We look at packaging, figure molds, paint precision, and materials.
- Other categories: From apparel to accessories, details like tags, labels, fabrics, and construction are checked with the same precision.
Tip: Clear, well-lit images speed up the process and increase accuracy.
Step 2 – Two Experts, One Mission
Unlike other services, every CheckCheck submission is reviewed by two independent authenticators.
- They work separately to avoid bias.
- Each uses brand-specific knowledge built from handling thousands of real and fake items.
- If they disagree, a senior authenticator steps in for a final decision.
This dual-authenticator approach ensures no single opinion ever determines your result.
Step 3 – Detail by Detail
Authentication isn’t just about spotting obvious flaws. Our experts go layer by layer:
- Stitching alignment and thread type
- Fonts, logos, and engravings
- Factory codes, serial numbers, and date stamps
- Material quality, texture, and finish (as visible from photos)
- Packaging consistency and inserts
Counterfeiters are getting better every year. That’s why we don’t rush—every detail matters.
Step 4 – Your Result, Backed by Experts
After review, we deliver a pass or fail verdict. For items that qualify, you’ll receive a Certificate of Authenticity (COA), a digital record proving your item is verified by CheckCheck.
This isn’t just a result; it’s peace of mind. Whether you’re buying, selling, or keeping a grail for your personal collection, you’ll know it’s the real deal.
Why It Matters
In 2025, counterfeit sneakers and luxury goods have never been more advanced. One small detail can make the difference between a $2,000 authentic pair and a worthless fake.
Our process protects you. We’ve authenticated over 2 million sneakers and thousands of luxury items, helping collectors and resellers worldwide stay safe in the resale market.
