What is the ORCID iD Validator?
Validate the checksum format of a 16-character ORCID iD. ITS Research Solution keeps the interactive tool above the explanation so you can calculate first and then review the method used.
Formula or method
ORCID uses the ISO 7064 MOD 11-2 checksum algorithm.
How to use this tool
Enter the requested values using consistent units, run the calculation and review the main result plus any supporting values. 0000-0002-1825-0097 is a commonly documented valid example.
Interpretation and limitations
Checksum validation does not confirm ownership of the ORCID record. Always check source data, units, rounding and discipline-specific requirements before using a result in assessed, published, regulated or high-stakes work.
Frequently asked questions
How is this result calculated?
ORCID uses the ISO 7064 MOD 11-2 checksum algorithm.
Can I use this result in formal academic or research work?
Use it as a transparent calculation aid, then verify the assumptions, units, rounding and any institution-, journal- or field-specific requirements before formal use.
