Numbers of ARK-assigning organizations since 2001.

ARKs serve as persistent identifiers, or web addresses (URLs) that don’t return 404 Page Not Found errors, which is the fate of the average URL after only 44 days. Researchers rely on ARKs for long term open access to the global scientific and cultural record.

Since 2001 over 8.2 billion ARKs have been created by more than 650 organizations — data centers, libraries, museums, archives, government agencies, and vendors. ARKs are the only mainstream, non-paywalled, de-centralized persistent identifiers that you can register to use in 48 hours. They are similar to DOIs, but more flexible and open.
