MOM Work Pass Verification for Contractors: From Registration to Site Access

Are your contractors, subcontractors and sub-subcontractors deploying workers with valid Work Passes?

Recent MOM investigations into suspected work pass offences at Changi Airport have highlighted the importance of stronger oversight over outsourced workforces.

For organisations managing large contractor workforces, the challenge goes beyond checking Work Pass validity. It's knowing who employs each worker, who's deploying them and who's actually working on site.

When these records are scattered across contractor submissions, spreadsheets and disconnected systems, maintaining workforce compliance becomes a time-consuming process.

Why Work Pass Verification Matters for Contractors in Singapore

Large facilities, infrastructure projects and industrial operations often rely on multiple tiers of contractors to deliver essential work.

A main contractor may engage subcontractors, who in turn engage sub-subcontractors to supply specialised services or additional manpower.

With each additional layer comes a greater challenge: maintaining accurate records of every worker and ensuring appropriate checks are completed before they enter the worksite.

Singapore's Ministry of Manpower (MOM) advises premise owners and main contractors to ensure that workers entering their buildings or worksites have valid Work Passes.

For organisations managing hundreds or thousands of workers across multiple facilities, this requires more than collecting Work Pass documents during initial onboarding.

Organisations need an ongoing process to verify worker credentials, maintain contractor accountability and monitor actual site attendance.

How to Check MOM Work Pass Validity in Singapore

MOM provides official methods for checking whether a foreign worker holds a valid Work Pass, including Work Permits, S Passes and Employment Passes.

These include:

• SGWorkPass App: Verify Work Pass validity by viewing a worker's digital pass or scanning the QR code on their Work Pass.
• MOM Check Work Pass and Application Status eService: Check the validity of a Work Pass using the worker's required identification details.

Organisations can access these services through MOM's official website.

However, Work Pass verification should not be treated as a one-time exercise.

A Work Pass that was valid during initial registration may subsequently expire or be cancelled. Without regular checks, contractor workforce records may no longer reflect the worker's current Work Pass status.

This becomes particularly difficult when workers are deployed across multiple sites, frequently change assignments or are registered under different subcontractor arrangements.

Why Manual Work Pass Verification Is Not Enough

Manual verification can work for small workforces. But as contractor networks expand, maintaining accurate records and ensuring that checks translate into actual site controls becomes increasingly challenging.

• Outdated Work Pass Records: Worker documents submitted during onboarding may no longer reflect their current Work Pass status. Without recurring verification, changes can go undetected.
• Limited Visibility Across Subcontractor Tiers: When contractors engage subcontractors and sub-subcontractors, organisations may lack a centralised view of each worker's employer, registration status and site enrolment.
• Disconnected Workforce and Access Systems: Work Pass verification records often sit separately from attendance and access control systems. A worker may have an invalid Work Pass but remain registered for site check-in unless the systems are connected.
• Time-Consuming Manual Administration: Operations teams may spend significant time collecting documents, checking Work Pass information, updating records and following up with contractors.

The key is to connect Work Pass verification directly to contractor resource management and workforce access control.

How Hubble Automates MOM Work Pass Verification and Contractor Workforce Management

Hubble connects contractor registration, daily MOM Work Pass verification and workforce access control in one integrated operations platform.

Rather than managing these processes separately, organisations can maintain a connected workflow from worker registration through to actual site check-in.

1. Manage Contractors and Subcontractors with Hubble Resource Management

Hubble centralises contractor resources, including companies, workers, equipment and supporting credentials.

Organisations can:

• Register and manage contractors, subcontractors and sub-subcontractors.
• Maintain centralised worker profiles and supporting documents.
• Track registered employers and contractor relationships.
• Manage worker enrolment across sites and facilities.
• Enable contractors to maintain their workforce information through digital self-service workflows.

This creates a structured resource base for organisations managing large, multi-tier contractor networks.

2. Automate Daily MOM Work Pass Verification

Hubble's MOM Work Pass Verification integration enables daily checks of registered workers' Work Pass information against MOM records.

Instead of relying solely on periodic manual checks, organisations can incorporate recurring verification into their workforce management processes.

This helps teams:

• Reduce manual Work Pass verification.
• Keep verification records up to date.
• Identify workers with invalid Work Passes.
• Strengthen ongoing oversight of contractor workforce credentials.

By connecting MOM verification to registered worker profiles, organisations can maintain more reliable workforce records without repeatedly checking documents across separate systems.

3. Connect Work Pass Verification to Workforce Access Control

Verifying Work Passes is only one part of the process. Organisations also need to control who can physically check in to their sites.

Hubble Workforce connects registered worker profiles to site access and attendance tracking, including integrated biometric turnstiles and mobile check-in workflows.

When Hubble Resource Management, MOM Work Pass Verification and Hubble Workforce are connected, workers with invalid Work Passes can be automatically blocked from checking in through configured turnstiles or mobile check-in.

This helps organisations enforce Work Pass validity checks at the point of site entry, rather than relying solely on administrative follow-up.

It also connects three critical questions in one workflow:

• Who is the worker? Their identity, employer and contractor registration.
• Is their Work Pass valid? Their latest verification status.
• Are they checking in to work? Their site access and attendance activity.

Work Pass Validity Is Only One Part of Contractor Workforce Compliance

A valid Work Pass does not necessarily mean a worker is authorised to perform every job assigned to them.

Organisations must also consider the worker's registered employer, occupation and applicable Work Pass conditions.

This distinction is particularly important in multi-tier subcontracting arrangements, where the company deploying a worker may not be the worker's registered employer.

While automated Work Pass verification helps confirm pass validity, employers and responsible parties must still ensure that workers are deployed in accordance with applicable regulations.

Strong contractor workforce governance requires accurate worker records, ongoing verification, clear contractor accountability and effective operational controls.

Frequently Asked Questions About MOM Work Pass Verification

How can I check if a MOM Work Pass is valid?

You can verify Work Pass validity using MOM's SGWorkPass app or its Check Work Pass and Application Status eService. These official services allow users to check whether a Work Pass is currently valid.

Can MOM Work Pass verification be automated?

Yes. Hubble's MOM Work Pass Verification integration supports daily checks of registered workers' Work Pass information against MOM records, reducing the need for repeated manual verification.

Can workers with invalid Work Passes be blocked from site entry?

Yes. When connected to Hubble Workforce and supported access-control systems, invalid Work Pass status can trigger check-in restrictions through configured biometric turnstiles or mobile check-in workflows.

How can organisations manage Work Pass verification across subcontractors?

Hubble Resource Management maintains centralised records of contractors, subcontractors, sub-subcontractors and their registered workers. Connecting these records to MOM verification and Hubble Workforce provides greater visibility over worker credentials and actual site attendance.

Does a valid Work Pass mean a worker is authorised to perform any job?

No. Workers must also comply with the conditions associated with their specific Work Pass, including applicable employer and occupational restrictions. Work Pass validity checks do not replace the need to verify lawful worker deployment.

Strengthen Contractor Workforce Compliance with Hubble

For organisations managing large contractor networks, workforce compliance should not depend on disconnected records, manual verification and periodic document checks.

By connecting Hubble Resource Management, MOM Work Pass Verification and Hubble Workforce, organisations can maintain visibility across contractor tiers, automate daily verification and prevent workers with invalid Work Passes from checking in through supported site access workflows.

Know your contractors. Verify their workers. Control who's checking in to your sites.
