How Crew Verification Actually Works
From identity checks to source verification with issuing authorities, here is what happens behind the scenes when crew credentials are verified.

Why verification exists
Maritime is a safety-critical industry. A forged Certificate of Competency or an expired STCW certificate puts lives at risk. Port state control inspections exist to catch these issues, but inspections are snapshots. They check what is presented at one moment in time.
Crew verification fills the gap between inspections. It provides continuous, proactive confirmation that every credential held by every crew member is genuine, current, and issued by a recognized authority.
Layer 1: Identity verification
The first step in any verification is confirming that the person presenting credentials is who they claim to be. Modern identity verification uses biometric comparison, matching a live selfie against the photo on an identity document.
The system checks document authenticity (security features, formatting, expiry) and performs a liveness check to prevent photos of photos or screen recordings from passing. This layer prevents identity fraud at the source.
Layer 2: Background screening
Background screening checks criminal records, sanctions lists, and employment history. For maritime, this includes checks against international sanctions databases, flag state blacklists, and port state control detention records.
The screening covers the jurisdictions relevant to the seafarer's nationality, countries of residence, and intended flag states of employment. Results typically return within one to three business days.
Layer 3: Document validation
AI-powered document validation examines uploaded certificates for authenticity markers. The system compares document formatting against known templates from training centres and flag state administrations worldwide.
It checks for inconsistencies in fonts, layouts, security features, and data fields. Cross-referencing between documents flags discrepancies, such as a certificate date that predates the required training course completion.
Layer 4: Source verification
The final layer contacts the issuing authority directly to confirm the credential was issued to the named individual with the stated details. This is the gold standard of verification and the most time-consuming step.
Source verification confirms that the certificate exists in the issuing authority's records, was issued to the correct person, and has not been revoked or suspended. Response times vary by authority, typically two to five business days.
What happens when something fails
If any verification layer flags an issue, the credential is marked as requiring attention. The crew member is notified with a clear explanation of what was flagged and what evidence is needed to resolve it.
Nothing is shared with employers until the issue is resolved. This protects crew from being unfairly judged on a verification discrepancy that may have an innocent explanation, such as a name change or a database delay at the issuing authority.
