Welcome to the free maritime certificate expiry checker by SeaArchive. Maintaining valid certifications is the absolute baseline requirement for any merchant navy career. Whether it's your basic STCW safety courses, your Certificate of Competency (COC), or your ENG1 medical fitness certificate, failing to renew a document can instantly ground you and halt your income.
This tool computes the precise expiry date of standard maritime certifications based on the date of issue. By selecting the classification length of your document (such as standard 5-year STCW or 2-year medical) and the exact date it was issued, our calculator will immediately verify its theoretical validity period.
An expiry date is only useful if you remember it before it arrives. Our platform's most powerful feature is our automated alert system. By clicking to enable a reminder, you can securely save this certificate into a free SeaArchive account. We will then automatically monitor this date and trigger prioritized email reminders to your inbox 60 days, 30 days, and 15 days before your certificate actually expires, ensuring you have ample time to book refresher courses.

Your requested validity period
Typically, if you refresh an STCW certificate within 6 months prior to its expiry, the new 5-year validity will start exactly from the old expiry date (rather than the date you took the course), rewarding early renewals. However, always verify this specific rule within your flag state's administration guidelines.
Once you click the reminder button and create an account, SeaArchive will automatically schedule an email dispatch queue for this specific document. When the 60-day threshold is breached, a notification will be pushed to your registered email address.
No. This calculation is strictly chronological based on the issue date you input. We do not connect to external national databases to verify the license or training center authenticity.
