# Troubleshooting invalid business type in Singapore

In Singapore, we verify your business type so we can collect the relevant information. If you are unable to proceed after providing the Unique Entity Number (UEN), there could be a few possible reasons:
### Invalid UEN
The UEN you entered cannot be found or is invalid in our system. Double-check the number for any typos or errors and try entering it again.
### Deregistered UEN
The UEN you provided is no longer valid, likely because the associated business has been deregistered. If your business is still actively operating, please ensure you're providing the latest and correct UEN.
If you've double-checked the UEN and business name and are still experiencing issues, please reach out to our support team for further assistance. We'll be happy to investigate the matter and help you successfully register your business in Singapore.
