Certification Guide
Everything you need to verify a Critical Care Registered Nurse (CCRN) credential, understand who issues it, and confirm it's active — straight from the AACN Certification Corporation's official records.
CCRN (Critical Care Registered Nurse) is a specialty certification for nurses who care for acutely and critically ill patients. It's issued by the AACN Certification Corporation, the credentialing arm of the American Association of Critical-Care Nurses (AACN) — the same body behind PCCN, CCRN-K, and CCRN-E. "AACN certification lookup" and "CCRN lookup" both point to the same verification system.
CCRN certification is valid for three years from the date earned. Renewal is available two ways: retaking the certification exam, or completing the Synergy CERP (Continuing Education Recognition Points) pathway, which requires ongoing critical-care practice hours plus accredited continuing education credits. AACN sends renewal reminders roughly 90 days before expiration — certifications that lapse must be re-earned by exam.

Nursing Credentials Explained
CCRN stands for Critical Care Registered Nurse — a specialty certification issued by the AACN Certification Corporation, a subsidiary of the American Association of Critical-Care Nurses (AACN).
Use the AACN Certification Corporation's official verification tool. Search by the nurse's name or certification number to confirm active status and expiration date — this is the only authoritative source.
AACN Certification Corporation is the issuing body; CCRN is one of several credentials it administers (alongside CCRN-K, CCRN-E, PCCN, and others). "AACN certification lookup" and "CCRN lookup" point to the same verification portal.
CCRN certification is valid for three years. Renewal requires either a renewal exam or continuing education (CERPs) plus current practice hours in critical care, submitted through AACN's renewal portal before the expiration date.
RNs or APRNs with an unencumbered U.S. license and at least 1,750 hours of direct bedside care of acutely or critically ill patients in the past two years (with 875 of those hours in the most recent year), or 2 years plus 2,000 hours over 5 years.
The certification itself expires on its 3-year cycle regardless of specialty change, but eligibility for renewal depends on maintaining qualifying critical-care practice hours — moving away from bedside critical care can affect your ability to renew by practice hours alone.
