An Account ID helps in easy identification of your account. The Account ID is created during activation, and by default, the administrator e-mail ID provided during activation is the Account ID.
You can add multiple licenses to an account using the same Account ID during activation. You can use the Account ID to perform licensing operations, use Tally Software Services, like Synchronisation, and so on.
You can log in to the Control Center and alter the Account ID, if required.
