Direct sources. Clear status. Practical public information.

Grants.gov lets applicants search for a package by Funding Opportunity Number or Opportunity Package ID. Its application-status help lists Opportunity Number, Opportunity Package ID, Competition ID, and Grants.gov Tracking Number as separate fields. They identify different objects and do not prove the same event.

Four-identifier crosswalk

Identifier	Object it identifies	What it does not prove
Funding Opportunity Number	The federal funding opportunity named by the awarding agency.	That a specific package was opened, submitted, or awarded.
Opportunity Package ID	A specific Grants.gov application package for an opportunity.	Applicant eligibility, complete forms, or submission.
Competition ID	A competition or application track associated with the opportunity/package when used.	That the applicant selected the right track or was accepted.
Grants.gov Tracking Number	A submitted application received through Grants.gov.	Agency award, cash received, spending, or outcome.

Reader tool

Copy each identifier from the live official record—never from memory.
Preserve the opportunity title, agency, package version, closing date/time zone, and observed date beside it.
Before submission, confirm the package and competition match the intended notice.
After submission, preserve the confirmation and validation status separately from the tracking number.
Call something an award only from the controlling agency award notice.

Human stop point: If the identifiers conflict, stop before submission and use the Grants.gov or awarding-agency help route. This card does not determine eligibility or authorize an application.
