+NotIdenticalTo
+===========
+
+.. versionadded:: 2.3
+    This constraint is new in version 2.3.
+
+Validates that a value is **not** identical to another value, defined in the
+options. To force that a value is identical, see
+:doc:`/reference/constraints/IdenticalTo`.
+
+.. caution::
+    
+    This constraint compares using ``!==``, so ``3`` and ``"3"`` are
+    considered not equal. Use :doc:`/reference/constraints/NotEqualTo` to compare
+    with ``!=``.

+Basic Usage
+-----------
+
+If you want to ensure that the ``age`` of a ``Person`` class is *not* equal to
+``15`` and *not* an integer, you could do the following:
+
+.. configuration-block::
+
+    .. code-block:: yaml
+
+        # src/SocialBundle/Resources/config/validation.yml
+        Acme\SocialBundle\Entity\Person:
+            properties:
+                age:
+                    - NotIdenticalTo:
+                        value: 15
+
+    .. code-block:: php-annotations
+
+        // src/Acme/SocialBundle/Entity/Person.php
+        namespace Acme\SocialBundle\Entity;
+
+        use Symfony\Component\Validator\Constraints as Assert;
+
+        class Person
+        {
+            /**
+             * @Assert\NotIdenticalTo(
+             *     value = 15
+             * )
+             */
+            protected $age;
+        }
+
+    .. code-block:: xml
+
+        <!-- src/Acme/SocialBundle/Resources/config/validation.xml -->
+        <class name="Acme\SocialBundle\Entity\Person">
+            <property name="age">
+                <constraint name="NotIdenticalTo">
+                    <option name="value">15</option>
+                </constraint>
+            </property>
+        </class>
+
+    .. code-block:: php
+
+        // src/Acme/SocialBundle/Entity/Person.php
+        namespace Acme\SocialBundle\Entity;
+
+        use Symfony\Component\Validator\Mapping\ClassMetadata;
+        use Symfony\Component\Validator\Constraints as Assert;
+
+        class Person
+        {
+            public static function loadValidatorMetadata(ClassMetadata $metadata)
+            {
+                $metadata->addPropertyConstraint('age', new Assert\NotIdenticalTo(array(
+                    'value' => 15,
+                )));
+            }
+        }
+
+Options
+-------
+
+.. include:: /reference/constraints/_comparison-value-option.rst.inc
+
