Help and description of the process of ordering services → Verifying domain ownership for SSL certificate issuance

Date of publication: 20.06.2025

Depending on the chosen domain verification method, you will be provided with options to verify through a DNS record or by placing a file.

We will review both domain verification options.

If for any reason you need to change the verification method selected during the order, open a request in your personal account.

1. DNS Verification

The most common method for verifying domain ownership. To confirm domain ownership, after payment, you will receive a TXT record that needs to be added to your DNS editor. Select the domain for which you are issuing the SSL certificate and add the TXT record, for example:

@ TXT _globalsign-domain-verification=8gqZjMbN62iSTd-eMev8TjBXAHLLIDhd_Rl4AJ4HYT

@ - represents the domain itself
TXT - record type
_globalsign-domain-verification=8gqZjMbN62iSTd-eMev8TjBXAHLLIDhd_Rl4AJ4HYT - the value, which is always unique and is provided here as an example.

After adding the record, you can notify us in response to the received email.

2. File Verification

For file-based verification, you must have access to the web server to create the necessary paths in the root directory and place the file with specific content.

The file name and the full URL where it should be accessible will be sent to you via email after payment.

Example:

URL — the path where the created file should be located

http://domain.tld/.well-known/pki-validation/81F9E13M185BF2111DA717R341F153B7.txt

Create the necessary folders and the file in the root directory of your domain on the web server. For Linux, use the mkdir and touch commands.

File Content — the data that needs to be added to the file.

For Linux, copy and paste the content into the file using nano.

After adding the record, you can notify us in response to the received email.

If everything is done correctly, within 1 hour, you will receive an email with the certificate. You will then need to install it on the relevant services, such as a web server or mail server. After installation, do not forget to restart the services.
