Validate your business identity with PSTN operators using Know Your Customer

APPLIES TO: Image of a checkmark for yesMicrosoft Calling Plans

This article provides an overview of the Know Your Customer value and process, and a guide for setting it up in your Teams admin center.

Know Your Customer, also known as KYC is a Public Switched Telephone Network (PSTN) industry practice that allows PSTN operators to validate the identity of their customer before providing communication services. It's a way to identify your business so that PSTN operators can help prevent your business from carrying illegal traffic, receiving nuisance calls, and more. KYC is designed to help prevent fraud and ensure national security, and therefore it's a PSTN operator investment into your risk management strategy.

In some countries and regions, KYC is a prerequisite for allowing customers to acquire or port telephone numbers. National Regulatory Authorities in different countries and regions set the rules for the information needed from users or businesses to get, transfer, or activate phone numbers for calling and messaging services.

Microsoft supports the KYC process by storing your KYC information in your tenant.

Having your KYC information stored in Teams expedites PSTN service requests and increases request approvals for Microsoft Calling Plan services wherever Microsoft offers Calling Plans.

Setting up KYC in your Teams admin center

To get your business verified, submit your business KYC information via the Teams admin center. A summary of the steps follows.

  • In the Teams Admin Center, go to Voice > Service configuration > Know Your Customer and select Add KYC information.

Step 1: Verify email address and domain

The business contact responsible for verification must enter the company or corporate email address associated with the tenant domain being verified. A one-time verification code is sent to the provided email address, and the recipient must submit the code to confirm ownership.

FAQ

Who reviews the submitted documentation?

Microsoft securely reviews the submitted documentation as part of the regular vetting review process.

Our organization operates across multiple global site locations. Is it necessary to submit a separate KYC for each location?

KYC verification is required on a per-tenant basis. You only need to submit one KYC verification per tenant. If your organization operates multiple tenants, a separate KYC submission is required for each one.

Our organization operates under a single tenant but has multiple global site locations. Who and Which location is responsible for submitting the KYC documentation?

Anyone authorized representative from any of your company’s locations may submit the form. It is essential that the information entered in the 'Business Information' section exactly matches the details provided in the primary supporting documentation.

I am a business owner but do not have a paid domain. How can I complete the KYC process successfully?

If you do not currently have a paid business email address, we recommend obtaining one through your preferred domain provider. Alternatively, you can purchase a domain for your organization directly through the Microsoft 365 Admin Center.

I accidentally entered wrong information in the Business information section, can I still change it?

To update the information, you may need to cancel the request. Note that cancellation is permitted only once and will become available after the submission has been reviewed and its status changes to 'Action Required'

Why was my KYC request rejected?

There are several reasons why a KYC submission may be rejected, and these reasons can vary by scenarios. A rejection does not necessarily indicate ineligibility. Microsoft may request additional documentation if certain required details are missing. In such cases, you may submit one or more of the approved secondary proof documents listed above for further review. For specific guidance related to your case, contact Microsoft Support.

Common scenarios resulting in KYC rejection

Generic email address provided

The email account provided isn't eligible to proceed. You're required to use a company domain to complete the verification process.

To complete the verification process, cancel and restart the process and provide an email address associated with your company domain. Also upload any supporting documentation like a domain registration / domain invoice from registration or renewal that lists entity/contact and domain as it is stated on your account.

Mismatch between information and supporting documents

The supporting documents don't match the information you entered. If you have a different document with matching information, upload it.

If it isn't possible to provide more documentation, cancel and restart the process and update your information to match any legal documents you're able to provide.

Supporting documents older than 12 months

The documents shared are too old to be considered for KYC verification.

All submitted documents must have been issued within the past 12 months and must not expire for at least two more months from the date of submission.
