 Here’s the list of [supported countries](https://smartystreets.com/docs/cloud/international-street-api#countries). You can pass the name, ISO-3, ISO-2, or ISO-N code (like `France`, `FRA`, `FR`, or `250`).
 
-**Note:** You’ll also need to use a fork of Geocoder until [this PR](https://github.com/alexreisner/geocoder/pull/1367) is merged.

 For Active Record, use:
 
 ```ruby
 class User < ApplicationRecord
-  validates_address country: "France"
+  validates_address country: "France", ...
 end
 ```
 
 Or use a proc to make it dynamic
 
 ```ruby
 class User < ApplicationRecord
-  validates_address country: -> { country }
+  validates_address country: -> { country }, ...
 end
 ```
 
-## Data Privacy
+## Internationalization (i18n)
 
-We recommend encrypting the street information for user addresses. Check out [this article](https://ankane.org/sensitive-data-rails) for more details.
+You can customize error messages with the [i18n](https://github.com/ruby-i18n/i18n) gem. In Rails, add to the appropriate `config/locales` file:
 
+```yml
+en:
+  mainstreet:
+    errors:
+      messages:
+        unconfirmed: Address can't be confirmed
+        apt_unconfirmed: Apartment or suite can't be confirmed
+        apt_missing: Apartment or suite is missing
+```
+
+## Data Protection
+
+We recommend encrypting street information and postal code (at the very least) for user addresses. [Lockbox](https://github.com/ankane/lockbox) is great for this. Check out [this article](https://ankane.org/sensitive-data-rails) for more details.

 ```ruby
 class User < ApplicationRecord
-  attr_encrypted :street, key: ...
+  encrypts :street, :postal_code
 end
 ```
