+Iban
+====
+
+This constraint is used to ensure that a bank account number has the proper format of
+an `International Bank Account Number (IBAN)`_. IBAN is an internationally agreed means
+of identifying bank accounts across national borders with a reduced risk of propagating
+transcription errors.

+Basic Usage
+-----------
+
+To use the Iban validator, simply apply it to a property on an object that
+will contain an International Bank Account Number.
+
+.. configuration-block::
+
+    .. code-block:: yaml
+
+        # src/Acme/SubscriptionBundle/Resources/config/validation.yml
+        Acme\SubscriptionBundle\Entity\Transaction:
+            properties:
+                bankAccountNumber:
+                    - Iban:
+                        message: This is not a valid International Bank Account Number (IBAN).
+
+    .. code-block:: xml
+
+        <!-- src/Acme/SubscriptionBundle/Resources/config/validation.xml -->
+        <class name="Acme\SubscriptionBundle\Entity\Transaction">
+            <property name="bankAccountNumber">
+                <constraint name="Iban">
+                    <option name="message">This is not a valid International Bank Account Number (IBAN).</option>
+                </constraint>
+            </property>
+        </class>
+
+    .. code-block:: php-annotations
+
+        // src/Acme/SubscriptionBundle/Entity/Transaction.php
+        namespace Acme\SubscriptionBundle\Entity\Transaction;
+
+        use Symfony\Component\Validator\Constraints as Assert;
+
+        class Transaction

+            /**
+             * @Assert\Iban(message = "This is not a valid International Bank Account Number (IBAN).")
+             */
+            protected $bankAccountNumber;
+        }
+
+    .. code-block:: php
+
+        // src/Acme/SubscriptionBundle/Entity/Transaction.php
+        namespace Acme\SubscriptionBundle\Entity\Transaction;
+
+        use Symfony\Component\Validator\Mapping\ClassMetadata;
+        use Symfony\Component\Validator\Constraints as Assert;
+
+        class Transaction
+        {
+            protected $bankAccountNumber;
+
+            public static function loadValidatorMetadata(ClassMetadata $metadata)
+            {
+                $metadata->addPropertyConstraint('bankAccountNumber', new Assert\Iban(array(
+                    'message' => 'This is not a valid International Bank Account Number (IBAN).',
+                )));
