ISSN for Blogs: Can Your Blog Get an ISSN and Is It Worth It? (2026)
In 2006 a popular post suggested every blogger should get an ISSN, the eight-digit number that identifies magazines and journals. The idea was that it would make blogs look legitimate and get them indexed in library databases. Is an ISSN for blogs still possible, and is it worth it in 2026? Here’s the honest answer.
Quick answer: Yes, some blogs can get an ISSN if they’re published as an ongoing serial with regular, editorially controlled issues or posts, a fixed title and a publisher in that country. Apply free through your national ISSN centre (in the US, the Library of Congress; in India, the ISSN National Centre at CSIR-NIScPR). It adds a library-catalogue identifier but has no SEO or ranking benefit.

What is an ISSN?
The International Standard Serial Number identifies serial publications such as journals, magazines, newsletters and some websites. It’s registered in the international ISSN Register. Unlike an ISBN, which identifies a book, an ISSN identifies the whole continuing publication.
Can a blog get one?
- The blog should publish regularly and be intended to continue indefinitely.
- It needs a stable title and a clear publisher name and address.
- Many centres want proof of several published posts or issues.
- Personal diaries, single-topic pages or sites that are mostly ads may be refused.
- Rules vary by country, so check your national centre.
How to apply
- Find your national centre on the ISSN International Centre website.
- In the US, apply online through the Library of Congress ISSN Center.
- Provide the title, URL, publisher details, frequency and screenshots or links to recent posts.
- Display the ISSN on your site (for example in the footer) once assigned.
Is it worth it?
- Useful for: academic blogs, online journals, newsletters and publications cited by libraries and researchers.
- Not useful for: SEO, traffic or monetisation; Google ignores ISSNs.
- Credibility mostly comes from good content, author expertise and transparency.
