Eight quick answers about the new ISJN system.
International Standard Journal Name (ISJN) is a journal identifier and web-resolution system designed for academic journals. Each assigned journal receives one unique five-letter code that can be used as a compact, memorable journal identity.
Every ISJN consists of exactly five uppercase English letters from A to Z, for example JSPIN. Numbers, punctuation, spaces, and lowercase forms are not used in the canonical identifier.
Yes. ISJN is completely free. There are no premium identifiers, registration charges, annual fees, renewal fees, or paid priority options.
The standard path is: obtain a valid ISSN, meet the requirements for inclusion in DOAJ, and then receive an ISJN assignment through the ISJN registry workflow. This helps keep the registry focused on verifiable scholarly journals.
No. ISSN, DOAJ, and ISJN serve different purposes. ISSN is the established serial identifier, DOAJ is an open-access journal directory, and ISJN provides a compact alphabetic journal name identifier and resolver. They are complementary.
ISJN codes are assigned under a standardized naming and uniqueness process rather than sold or reserved. The code is derived from the journal name while avoiding collisions with codes already assigned in the registry.
An assigned ISJN is intended to remain permanently linked to the journal it identifies and is not transferable to another journal. Material title changes or metadata corrections can be reviewed by the ISJN team.
The new ISJN service shares the OAJF scholarly database and combines journal metadata and signals from sources such as DOAJ, Crossref, and OpenAlex. The resolver points users to the journal’s official homepage. Corrections can be sent to info@isjn.org.
