01 / EDITORIAL NOTE
Who publishes this project
Check The Tag was created as a free garment-care reference by publisher Alexios Papaioannou. The site is not affiliated with ISO, GINETEX, ASTM, the FTC, Woolmark or the manufacturers of the garments you own. It is a reference, not a testing laboratory.
02 / EDITORIAL NOTE
What we check
Mark meanings are drawn from identified published reference editions. Each symbol detail page links to the relevant public source, and U.S. historical reference markings remain separate from modern international guidance. Garment-specific handling must still follow the sewn-in care label.
03 / EDITORIAL NOTE
What we do not claim
We do not pretend to have conducted original shrinking tests, photographed products that we have not photographed, or used a machine-vision model with validated accuracy. The app does not guarantee that a cleaning method will work for every garment.

Editorial corrections
Use the downloadable correction report on the Sources page to capture a suspected mismatch. Its report is generated on your device and is not secretly sent to a server. For standards changes, we update the reference edition, revision date and changelog before shipping a new release.
