# Test information
# Certificates for test users
If you already have a certificate for production BankID, you can log in to https://demo.bankid.com (opens new window) and issue test certificates as explained below. This is also possible using an existing valid test certificate.
- Prepare a name and "personnummer" (Swedish national identification number) for the test users you would like to create.
- The personnummer should be a valid combination of 12 digits. If you do not have a personnummer, you may construct one for testing via <www.personnummer.nu>. This must be a properly formatted national ID including a control digit.
If you do not have a BankID, you may order a code from https://demo.bankid.com/CreateCode.aspx and issue new test-users.
