Little Pro on 2015-12-30

A REACH registration number is an 18-digit number assigned by the European Chemicals Agency (ECHA). It is the most straightforward proof that one company has fulfilled their registration obligation for a substance under the EU REACH regulation. After successful completion of a (pre-) registration, a registrant can download a submission report from REACH-IT with a REACH registration number on it.

The picture below is an example of a submission report with a registration number on it.
