Over 1,900 independent badge issuers - ranging from formal and informal educational institutions; multinational corporations; industry associations; non-profits; and groups interested in professional development - have aligned with the Open Badge standard.
We manage the Participating Issuers List based on issuers self-reporting their badge activity to us: http://www.openbadges.org/participating-issuers
There is also a community-edited wiki page listing open badge issuers: https://wiki.mozilla.org/Badges/Issuers
We have a great community-curated collection of badge issuing platforms which can be accessed here: http://bit.ly/platform-chart
