Summary:
Starting January 2026, Teams Phone porting requires a one-time Know Your Customer (KYC) process via Teams Admin Center. Admins must submit business info and documents for validation before port-in requests. Existing numbers are unaffected. This applies globally and includes all tenants, with role-based access control via Entra ID.
Details:
[Introduction]
We're extending the Know Your Customer (KYC) requirements to the Teams Phone porting process in all markets. Teams administrators will need to submit general business information and supporting documents via Teams Admin Center before initiating a port-in request. This one-time process allows Microsoft to validate businesses and fulfill regulatory requirements, helping protect our phone services from misuse, such as spam calls and voice phishing (vishing).
If your organization has already completed the KYC onboarding (for example, when acquiring new telephone numbers), no further action is required. You will not need to complete the process again and can disregard this message. If you are unsure of the KYC status of your organization, please visit the Know Your Customer page in the Teams Admin Center to verify it and complete it if necessary.
[When this will happen:]
General Availability (Worldwide, GCC): We will begin rolling out early January 2026 and expect to complete by late January 2026.
