Hello @06419979,
Welcome to Microsoft Q&A forum.
You can directly sign in/activate Visual Studio by using the subscription that you purchased(normally, use the email address to which the subscription was assigned, to sign in VS).
After you sign in Visual Studio, Visual Studio will be activated.
You can check your subscription and related information here => https://my.visualstudio.com/.
BTW, here’s a helpful document: Sign into Visual Studio which provides more details.
You’re prompted to sign in to your account. Use the email address to which the subscription was assigned. (This address is normally the one where you received a notification that a subscription was assigned to you.)
Feel free to let us know if you have any further concerns:)
Best Regards,
Tianyu
