GS1 is an international organisation which defines the specifications for barcodes, among other things. The agreement established between GS1 and the ISSN International Centre allows ISSN numbers to be used in barcodes according to the EAN13 specifications, with the prefix 977 reserved for serial publications.

The SAIISA project was launched at the beginning of 2013. It involves semi-automatically assigning an ISSN to nearly 30,000 serial publications, of which approximately 10,000 are “dead” publications. SAIISA is led by 3 entities:
- the ISSN International Centre,
- the Italian ISSN National Centre (hosted by the Italian National Research Council), and
- the Italian union catalogue of serial publications (ACNP), hosted by the University of Bologna.

The ISSN International Centre and its network take part in Think.Check.Submit, a new campaign led by representatives from ALPSP, DOAJ, INASP, LIBER, OASPA, STM and individual publishers. This campaign will help researchers understand their options, and key criteria they should check before submitting their papers for publication.

DOAJ and the ISSN International Centre signed a Memorandum of Understanding in December 2015. The purpose of this agreement is to promote both parties and exchange metadata about quality, open access journals in the framework of ROAD service. The benefit of this working agreement is to give an insight about trusted peer-reviewed open access journals. Being indexed in the DOAJ means that the journals considered adhere to high levels of quality regarding best practices.

The ISSN International Centre and ProQuest work together to improve electronic loading of serial titles worldwide. Further information available at http://www.proquest.com/about/news/2016/ISSN-and-ProQuest-Work-to-Improve-Electronic-Loading-of-Serial-Titles.html
