WIPO PROOF tokens are date and time stamped digital fingerprints of your file; these tokens benefit from indefinite validity and, by default, WIPO stores them for a period of 5 years. During the storage period, they can be downloaded at any time. All WIPO PROOF tokens can be verified online for free and a WIPO Account is not required to verify tokens. WIPO PROOF tokens can also be verified by independent platforms utilising the PKI technology.

For more information about the token validity, see also “How long is my WIPO PROOF token valid for?” in our FAQs.
