DOI Suffix

Each suffix shall be unique to the prefix element that precedes it. The unique suffix can be a sequential number, or it might incorporate an identifier generated from or based on another system used by the registrant (for example, ISAN, ISBN, ISRC, ISSN, ISTC, ISNI; in such cases, a preferred construction for such a suffix can be specified, as in Example 2). No length limit is set to the suffix by the DOI System.

•Example 1
10.1000/123456: DOI name with the DOI prefix "10.1000" and the DOI suffix "123456"

•Example 2
10.1038/issn.1476-4687: DOI suffix using an ISSN
To construct a DOI suffix using an ISSN, precede the ISSN (including the hyphen) with the lowercase letters "issn" and a period, as in this hypothetical example of a DOI name for the electronic version of the scientific journal Nature.
