Authentication as an artform, by BrandCo Paris
At BrandCo Paris, authenticity is a sacred ritual, a meticulous process perfected over more than 15 years of dedication to excellence.
Every piece that passes through the BrandCo atelier is subjected to a six-step authentication protocol that blends human expertise with cutting-edge technology, setting a new industry standard for second-hand luxury.

The six stages of BrandCo Paris authentication :

Sourcing with discernment
It all begins with due diligence and a rigorous pre-selection of our purchasing partners, whether professionals or individuals.
Each is evaluated on their product expertise and historical reliability. Regular suppliers are rated and filtered according to BrandCo’s internal scoring system to ensure only the most trustworthy sources remain in the supply chain.
Initial inspection by in-house experts
Upon arrival at our office, each item undergoes a first authentication by a junior expert with at least three years of experience in the luxury goods sector.
This early evaluation is the first filter in our multi-layered quality control.


Microscopic double verification
Every detail counts. A second, microscopic analysis is conducted to verify elements invisible to the naked eye: stitching precision, serial tags, font consistencies, and material grain.
This process ensures a double authentication
Senior-level validation
All high-end products – valued at €100 or more, or those with intricate features – are then reviewed by a senior expert.
Their advanced expertise allows for the identification of even the subtlest inconsistencies or brand-specific quirks.


Spectrometer testing for precious materials
For Hermès and Chanel items incorporating precious metals, we employ spectrometer analysis, a scientific method to verify the composition of clasps, hardware, and decorative elements.
This provides an additional layer of security, particularly for pieces with high intrinsic and resale value.
Certification and traceability
Once a piece has passed all five stages, it is issued a BrandCo certificate of authenticity.
This document includes detailed product information, the item’s original production number, and a unique internal tracking code, enabling full traceability throughout its new journey.
