NCCS Core Files use the following naming convention:

[NCCS file locator].core[4 digit year of release][sector code]["_full990" suffix (if applicable)].csv

Where:

[NCCS file locator] =

nccs: 501(c)(3) Public Charity or Private Foundation files

coreco: "Other" tax-exempt 501(c) organizations, excluding 501(c)(3)

[sector code] =

pc: 501(c)(3) public charities

pf: 501(c)(3) private foundations

co: "other" 501(c) organizations, excluding 501(c)(3) organizations

[_full990 suffix] =

"_full990": designation for a "Full 990 file", if applicable

Examples:

nccs.core2011pc.csv refers to the Core 2011 file for public charities. This corresponds to the data dictionary entry for "Core 2011 PC"

coreco.core2013co_full990.csv refers to the Core 2013 Full 990 file for "other" 501(c) tax-exempt organizations. This corresponds to the data dictionary entry for "Core 2013 501(c) others Full 990".
