What the site is
checkthepiece offers free decoders that explain what brand codes encode. The results are general information based on published sources and observations, which can be incomplete or wrong.
The site is not an authentication service. A result never confirms or rules out that an item is genuine, and should not be the only basis for buying, selling or pricing anything.
No warranty
The site is provided as is, without any warranty. To the extent the law allows, we are not liable for decisions made on the basis of its results.
Trademarks
Brand names belong to their owners. We are not affiliated with or endorsed by any brand named on this site.
Changes
We may update the decoders and these terms.
