[Base, Advanced, and Enterprise tiers only] A site ID is a unique string that identifies your installation of Teradata Software for Azure to Teradata Customer Support. A site ID is not required to use Teradata Software for Azure but is required for Teradata Customer Support. (The Developer tier includes only Community support and does not use site IDs.)
Existing Teradata customers with a site ID for a Teradata system on a different platform cannot use that site ID for Teradata Software for Azure. You must obtain a site ID specific to your Azure deployment.
When you register for Teradata Customer Support at https://www.teradata.com/Products/Cloud/Do-it-yourself/Azure, specify a site ID, starting with AZRTDB and followed by 9 alphanumeric characters. Within two business days after completing registration, you will receive email containing your Master Customer Record, user ID, password, and confirmed site ID.
