[Base, Advanced, and Enterprise tiers only] A site ID is a unique string that identifies your installation of Teradata® VantageCloud Enterprise on Azure (DIY) to Teradata Services. A site ID is not required to use Teradata® VantageCloud Enterprise on Azure (DIY) but is required for Teradata Services. (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® VantageCloud Enterprise on Azure (DIY). You must obtain a site ID specific to your Azure deployment.
When you register for Teradata Services at https://www.teradata.com/Cloud/Azure/Do-it-Yourself/Support-Registration, 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.
