+# OCI Identity Domains – SMS Enrollment Reference Implementation
+
+## Overview
+
+This repository accompanies the Oracle Blog:
+
+**Verify Phone Numbers During User Registration Without Adding Friction to Sign-In**
+
+It demonstrates how to implement phone number verification during user registration using Oracle Cloud Infrastructure (OCI) Identity Domains and the public Identity Domains REST APIs.
+
+Rather than enforcing SMS during every authentication, this solution uses SMS solely to verify ownership of the mobile number during onboarding while allowing organizations to enforce Multi-Factor Authentication (MFA) later through Identity Domains Sign-On Policies.
