Overview
Every Twilio customer automatically gets an Organization when they sign up (auto-created since May 2024 for new signups; since June 2024 for existing paying customers). An Organization is the top-level container that groups accounts, users, and security policies. The creation has no effect on existing account functionality. Most developers never need to touch it — but as soon as you have multiple accounts, teams, or compliance requirements (SSO, HIPAA), Organization setup becomes essential.
Hierarchy: Organization > Accounts > Subaccounts
| Layer | What it is | When you need it |
|---|---|---|
| Organization | Centralized governance: users, accounts, domains, SSO | Multiple teams or accounts, SSO, HIPAA designation |
| Account | Application boundary: all Twilio products, resources, billing live here | Always — you need at least one |
| Subaccount | Isolated partition under an account: separate resources, consolidated billing | Multi-tenant apps, per-customer isolation |
