Understanding Grant Numbers
A grant number provides unique identification for the grant. The figure below shows an example of a complete NIH grant number (5 R01 HL123451-01A2).
The grant number is composed of the following parts:
- Type Code. The Type code indicates whether the application is new, a renewal, a noncompeting applications, or other type.
- Activity Code. The Activity code lists the type of grant that has been applied for.
- Institute Code (Administrating Organization). The Institute code (also known as the IC or Institute/Center code) is a two-letter code for the name of the NIH Institute or Center.
- Serial Number. The serial number is a unique five or six digit number that identifies the specific application and is assigned by the NIH Center for Scientific Review (CSR).
- Support Year. The Support Year indicates the current year of support (for example, 01 is a new grant).
- Suffix Code. The Suffix Code (optional) is a code used for supplements, amendments, or fellowship institutional allowances.
For information about specific codes and their meaning, see the Adobe PDF report located at http://grants.nih.gov/grants/funding/ac.pdf.
