 This article provides examples for using general claims transformations of the Identity Experience Framework schema in Azure Active Directory B2C (Azure AD B2C). For more information, see [ClaimsTransformations](claimstransformations.md).
 
+## CopyClaim
+
+Copy value of a claim to another. Both claims must be from the same type.
+
+| Item | TransformationClaimType | Data Type | Notes |
+| ---- | ----------------------- | --------- | ----- |
+| InputClaim | inputClaim | string, int | The claim type which is to be copied. |
+| OutputClaim | outputClaim | string, int | The ClaimType that is produced after this ClaimsTransformation has been invoked. |
+
+Use this claims transformation to copy a value from a string or numeric claim, to another claim. The following example copies the externalEmail claim value to email claim.
+
+```XML
+<ClaimsTransformation Id="CopyEmailAddress" TransformationMethod="CopyClaim"> 
+  <InputClaims>
+    <InputClaim ClaimTypeReferenceId="externalEmail" TransformationClaimType="inputClaim"/>
+  </InputClaims>
+  <OutputClaims>
+    <OutputClaim ClaimTypeReferenceId="email" TransformationClaimType="outputClaim"/>
+  </OutputClaims>         
+</ClaimsTransformation>
+```
+
+### Example
+
+- Input claims:
+    - **inputClaim**: [email protected]
+- Output claims:
+    - **outputClaim**: [email protected] 
+
 ## DoesClaimExist
 
 Checks if the **inputClaim** exists or not and sets **outputClaim** to true or false accordingly.
