NIH grant applications and biosketches must cite PubMed Central reference numbers (PMCID) for all articles accepted for publication on or after April 7, 2008 that resulted from your previous NIH grants. (Note that the PMCID is NOT the same as the PMID [PubMed ID] found on all articles in PubMed.)
If a manuscript was submitted through the NIH Manuscript Submission System (NIHMS) and a PubMed Central reference number is not yet available, include the NIH Manuscript Submission System reference number (NIHMS ID) instead.
Example, before PMCID is available:
The same article, once the PMCID is available:
If you publish in a journal that submits articles for you, a PMCID may not be assigned until several weeks after publication. During this time, please indicate compliance with the policy by indicating “PMC Journal - In Process”.

PubMed Central provides a useful PMID : PMCID Converter that will locate an articles PMCID based on it's PMID (PubMed ID). If the PMCID is not yet available, the converter will give you the NIHMS ID instead.
Your Librarian Liaison can also help you find PMCID or NIHMS ID numbers.
