Registering for the BOI's Single Window System

Who Needs to Register?

All companies currently using the Single Window System for visa and work permit services must register for the new system. This registration includes a mandatory identity verification process to grant you access.

Key Dates

Registration Begins: August 1, 2025 Starting this date, the BOI will officially open registration for authorized individuals or their designated representatives from each company to access the new Single Window System.

How to Register

The registration process varies slightly based on the applicant's nationality:

• For Thai Nationals: You will verify your identity using the ThaID application. When you select this option, the system will redirect you to the ThaID app for verification. Once successful, your information will automatically populate the registration form. You can review and edit this information before submitting your registration request.
• For Foreign Nationals: You will verify your identity via email.

After Submitting Your Registration

Once your registration request is submitted, a BOI official will review and process it according to their procedures. Upon completion of the review, you will receive an email with instructions on how to set your password to access the system.

Important Notes:

• Initial Registration Limit: For the very first registration, only one person per company will be allowed to register.
• Company User Management: After this initial registration is complete, your company will be able to manage its own users within the system.
• Identity Verification for Representatives:
  • Thai authorized individuals or representatives must verify their identity through the ThaID application.
  • Foreign authorized individuals or representatives must verify their identity via email.

How to Log In

Once you are registered and password is set, you can log in to the system using two methods:

1. Using the National ID number/email and password.
2. Logging in with ThaID.
