The Number authority table (AT) is a controlled vocabulary listing a set of cardinal and ordinal numbers in the 24 official languages of the EU. It is mainly used for numbering the issues. It contains numbers from 1 to 31, decimals from 40 to 100 and some bigger round numbers. In addition to a reference either to CAR (cardinal) or ORD (ordinal), the authority code contains the number itself. The Number AT is maintained by the Publications Office of the European Union on the EU Vocabularies website.
