+
+The `metro_code` data in our GeoIP products and services is a no-longer-maintained code. Because Google does not use or publish these codes any longer, the `metro_code` field has now been deprecated in our GeoIP products and services.
+
+**What should I do?**
+
+The field will not be removed from our databases and existing values will continue to be populated, so you can continue using it if you find it valuable.
