Who can apply for a code signing certificate ?

A code signing certificate can be issued for natural persons (e.g. individual developers, sole traders) and registered companies and organizations (e.g. Ltd., Inc., LLC, associations, etc.). However, only COMODO currently issued certificates for individual developers.

What is the difference between a Standard Code Signing Certificate and a Certificate with Extended Validation ?

Code Signing Certificates with Extended Validation (EV) are subject to a very strict validation process and must be stored on a hardware token. EV certificates can only be issued for companies that are registered in a commercial register. In addition to maximum security due a hardware token, EV certificates also immediately enable reputation with Microsoft Smartscreen. This is a great benefit especially for software startups that do not yet have high download rates.

Important steps for a smooth validation process

During configuration, the private key and the Certificate Signing Request (CSR) are automatically created. Currently, only the Firefox browser fully supports automated creation. Please use a current version of the Firefox browser throughout the whole configuration process !

Since a Code Signing Certificate confirms the identity of the signer, the Certificate Authority must be able to validate your data through a trusted 3rd party source. The Certificate Authority will check the following details:

  • – Name of person or legal entity
  • – Applicant’s address
  • – Telephone number of the applicant

Individual developers must submit their name and surname (e.g.: “John Smith”) and registered companies must apply in the name of their legal entity (exactly as registered with local authorities).

Fictitious trade names (such as “XY Software” for a non-registered business) will not be accepted !

Validation of the data must be performed using a trusted third-party source.
Currently only the Dun & Bradstreet Business Database (DUNS®) is accepted by the Certificate Authorities.

How does the validation process work ?

After submitting the application to the Certificate Authority, they compare your data with the DUNS® database.

Therefore it is important to keep your DUNS® record up to date and also publish a valid the telephone number:

 -> Request DUNS® number

In case you do not want to apply for a DUNS® number, vetting can also be done using legalized documents.

Instructions for the so-called face-to-face validation conducted by COMODO can be found here:
COMODO Face-to-Face Verification Instructions

All documents must be certified by a lawyer or notary public !

Once the applicant’s data has been verified by the Certificate Authority, the Certificate Authority will initiate the automated callback.
You will receive a link to request an automatic call to the official phone number. After entering the verification code, the certificate will be issued within a few minutes.

Note: Verification of the telephone number is a mandatory step. It is essential that a valid telephone number is published in the DUNS® database.
