Verification of Digital Certificate and Transcript

Welcome to the SIM Digital Verification Platform. Graduates who have successfully completed the programme(s) awarded by the Singapore Institute of Management (SIM) may verify the authencity of your digital certificates and transcripts through the Opencerts verification tool.

OpenCerts verification tool

Upload or drag and drop the (.opencert) file into the verification window below.

  • If the file can be successfully opened in the viewer with no error message(s), it shows that the file is verified and is authentic. A successful validation on the SIM Verifier page is a valid confirmation that the digital academic certificate and transcript are authentic.
  • If the digital academic certificates and transcripts have been forged, tampered with, or are invalid, the verification will return a corresponding failure status.

About OpenCerts

  • OpenCerts, developed by GovTech Singapore, is an online platform based on the blockchain technology that offers an easy way to issue, check and verify academic qualifications.
  • Each digital certificate/transcript is assigned a cryptographic proof (a digital fingerprint).
  • This digital fingerprint is stored on the blockchain, a decentralised online ledger. This means that multiple copies are stored in different servers and records made on it cannot be altered or destroyed by a single person.
  • When your certificate/transcript is being verified by employers, the certificate/transcript data is checked against its code on the blockchain for validity and signs of tampering.
  • The verification results will show whether the digital academic certificate and/or transcript uploaded are authentic.

Benefits of OpenCerts

  1. Tamper-proof
    When a digital certificate and a digital transcript is issued by SIM, a unique hash is generated. Any modification to the content of the .opencert file will result in the file having a different hash. As a result, the verification will fail as the authenticity of the file has been tampered.
  2. Authenticity
    An untampered digital certificate/transcript will display the authencity of the certificate/transcript to the viewer. Graduates can easily share their .opencert file with potential employee or other universities and they can then authenticate the graduates’ credentials through the Verify Digital Certificate/Transcript service.
  3. Portability
    The (.opencert) file contains your digital certificate and digital transcript and can easily be retrieved from your email or stored on your computer or devices. This reduce the chance of losing or misplacing physical certificates/transcripts.


  • Graduates are individually responsible for maintaining access to the digital academic certificate and/or transcript issued to them.

  • You can rename the .opencert file but you must retain the file extension (.opencert). Any edits made to the content of the .opencert file will result in an authentication failure during the verification process.

  • The digital academic certificate and transcript will only expire if an expiry or revocation was put in place by the issuer and this will be displayed during verification. Otherwise, the digital academic certificate and transcript will remain valid and authenticated perpetually.

  • The handling of the digital academic certificate and transcript must comply with the data protection obligations of the PDPA Act.

Step 1: Create an account

  • When your institution issues a certificate and/or transcript to you for the first time, you will receive an email with instructions and a link to create your password.

  • Simply follow the instructions to complete the set up. Once your account has been created, you may log in and to view your certificate at any time.

Step 2: Access your dashboard and certificate

  • All certificates and/or transcripts tied to your account are accessible from the dashboard.

  • You can either export the certificate and/or transcript to .pdf or .opencert format. Do not double click on the opencerts file.

  • You can save the .opencert file on your computer, just like any other softcopy files which you have.

Step 3: Share your certificate

  • From the Documents page, click the Share To button to enable sharing and share the certificate with others. You can choose to obfuscate selected information before sharing your certificate.

  • You can share the file as an attachment via email, download the file, print the file, or share it on social media via a sharing link or QR code. You can also set an expiry for the link before sharing.

  • You can send the .opencert file to individual or organisations, and direct them to the current page to verify the authencity of your academic qualifications digitally.

  • Your certificate and transcript can also be exported as a PDF for sharing. Do note that the PDF file is not tamper-proof and cannot be verified on the verifier page.
