Are ISSN also assigned to online publications/blogs?

Yes. ISSN can also be assigned to online publications or blogs if these are serial publications that are numbered or dated. ISSN are not assigned to mailing lists, websites with descriptions of customer offers and services provided by companies, or purely private websites.

Are you unsure whether your online publication or blog meets these criteria? We will gladly check this for you if you send us the internet address. Just send an e-mail to issn@dnb.de .

In general, you can only request an ISSN for online publications after they have been published in the internet. Please include the activated main internet address with your application.
