ISSN Validator

Validates an ISSN's format and check digit, then separately checks whether it matches a journal in JCF's dataset — format validity and a JCF match are two different facts, shown separately.

About this tool

Purpose
Validates an ISSN's format and checksum, and checks whether it matches a journal in JCF's own dataset.
Try this
Enter an ISSN such as 0028-0836.
Expected result
Whether the ISSN is validly formatted, and the matching JCF journal record if one exists.
Privacy
Checks JCF's own already-collected data — nothing you enter is stored.
Limitations
A validly-formatted ISSN with no JCF match only means JCF has no matching journal record — not that the ISSN itself is fake.
