==Range== UN numbers range from UN 0004 to about UN 3550 (UN 0001 β UN 0003 are no longer in use) and are assigned by the United Nations Committee of Experts on the Transport of Dangerous Goods. They are published as part of their ''[[Recommendations on the Transport of Dangerous Goods]]'', also known as the ''Orange Book''. These recommendations are adopted by the regulatory organization responsible for the different modes of transport. There is no UN number allocated to non-hazardous substances.
