Well you asked the community but the best one to answer is really the one who sells the device to you. @Gordon here or even Adafruit or whoever sells them - table of sellers here http://www.espruino.com/Order#puckjs
AFAIK the normal non-lite Puck.js is based on Raytac MDBT42Q module https://www.raytac.com/product/ins.php?index_id=31 see also photos here http://www.espruino.com/Puck.js#pinout so any certification that Raytac got for the module is valid for PuckJS too. That is also why such easy to use generic modules exist - to avoid the need of another certification. For US the info is here https://fccid.io/SH6MDBT42Q
For the lite version it is much more interesting as this is custom PCB.
That was the hardware. As for Bluetooth software there is also certification/qualification of the Bluetooth stack, Espruino uses standard Nordic SoftDevice and Nordic keeps qualification ids in table here

Espruino uses S132 SoftDevice version 3.x so QDID is 85568

When checking the shop page https://shop.espruino.com/puckjs I don't see certification info there. It could be useful indeed to have something there.
However there is something here http://www.espruino.com/Puck.js#information - it links http://www.espruino.com/files/Puck.js-CE.pdf
And https://www.espruino.com/datasheets/MDBT42Q-E.pdf mentions certifications too.
Take this as a community member answer :-)
