+title: Tagging and Labeling
+---
+
+Tags and labels are a way to organize and categorize your resources. In this guide, you'll learn how to annotate your
+Konnect entities managed by {{site.kgo_product_name}} with tags and labels (depending on particular entity's support for
+those).
+
+{% include md/kgo/konnect-entities-prerequisites.md disable_accordian=false version=page.version release=page.release %}
+
+## Labeling
+
+Labels are key-value pairs that you can attach to objects. As of now, the only Konnect entity that supports labeling is
+the [KonnectGatewayControlPlane](/gateway-operator/guides/konnect-entities/gatewaycontrolplane). You can add labels to
+the `KonnectGatewayControlPlane` object by specifying the `labels` field in the `spec` section.
+
+```yaml
+echo '
+kind: KonnectGatewayControlPlane
+apiVersion: konnect.konghq.com/v1alpha1
+metadata:
+  name: gateway-control-plane
+  namespace: default
+spec:
+  labels: # Arbitrary key-value pairs
+    environment: production
+    team: devops
+  name: gateway-control-plane
+  konnect:
+    authRef:
+      name: konnect-api-auth # Reference to the KonnectAPIAuthConfiguration object
+  ' | kubectl apply -f -
+```
+
+You can verify the Control Plane was reconciled successfully by checking its status.
+
+```shell
+kubectl get konnectgatewaycontrolplanes.konnect.konghq.com gateway-control-plane
+```
+
+The output should look similar to this:
+
+```console
+NAME                    PROGRAMMED   ID                                     ORGID
+gateway-control-plane   True         <konnect-control-plane-id>             <your-konnect-ord-id>
+```
+
+At this point, labels should be visible in the Gateway Manager UI.
+
+## Tagging
+
+Tags are values that you can attach to objects. All the Konnect entities that can be attached to a
+`KonnectGatewayControlPlane` object support tagging. You can add tags to those entities by specifying the `tags` field
+in their `spec` section.
+
+For example, to add tags to a `KongService` object, you can apply the following YAML manifest:
+
+```yaml
+echo '
+kind: KongService
+apiVersion: configuration.konghq.com/v1alpha1
+metadata:
+  name: service
+  namespace: default
+spec:
+  tags: # Arbitrary list of strings
+    - production
+    - devops
+  name: service
+  host: example.com
+  controlPlaneRef:
+    type: konnectNamespacedRef
+    konnectNamespacedRef:
+      name: gateway-control-plane
+  ' | kubectl apply -f -
+```
+
+You can verify the `KongService` was reconciled successfully by checking its `Programmed` condition.
+
+```shell
+kubectl get kongservice service -o=jsonpath='{.status.conditions}' | jq '.[] | select(.type == "Programmed")'
+```
+
+The output should look similar to this:
+
+```console
+{
+  "observedGeneration": 1,
+  "reason": "Programmed",
+  "status": "True",
+  "type": "Programmed"
+}
+```
+
+At this point, tags should be visible in the Gateway Manager UI.
