Your CAC card expiration date isn’t just a suggestion – it’s a hard deadline that can lock you out of everything from email to building access. But the renewal process is simpler than most people think.

Key fact: You can renew your CAC up to 150 days before expiration, and there’s usually a 30-day grace period after.

CAC Expiration Timeline

Standard CAC Validity:

• Active Duty: 3 years from issue date
• Reserve/Guard: 3 years (same as active duty)
• Retirees: 5 years from issue date
• Civilians: Varies (usually 1-3 years based on position)
• Dependents: Matches sponsor’s timeline or 3 years

Where to Find Your Expiration Date:

1. Look at the front of your CAC card
2. Find “EXP DATE” field
3. Format is MM/DD/YYYY
4. Mark your calendar 120 days before this date
