What is my Tenant ID?
Enter any organisation's domain and resolve its Microsoft Entra ID (Azure AD) tenant. Runs entirely in your browser — nothing is sent to our servers.
◆ What is a tenant ID?
Every Microsoft 365 / Entra ID organisation has a unique tenant ID — a GUID like 72f988bf-…-2d7cd011db47. It identifies the directory behind sign-in, Conditional Access, guest invites, and app registrations.
◆ How this works
We query the tenant's public discovery document at login.microsoftonline.com/{domain}/v2.0/.well-known/openid-configuration and read the tenant GUID from its issuer. The same data Microsoft exposes to every sign-in.
◆ Is it private?
Yes. The lookup happens directly between your browser and Microsoft. evoICT never sees the domain you enter, and nothing is stored or logged on our side.
◆ When you'd need it
Setting up cross-tenant access, B2B guest sharing, Conditional Access scoping, PowerShell / Graph automation, or migration projects — all of which reference the tenant by its ID.
