# Confluent Resource Names (CRNs) on Confluent Cloud Confluent Resource Names (CRNs) provide a uniform way to uniquely identify resources such as a Kafka cluster, topic, or consumer group, and are used in audit logs. Each CRN is a uniform resource identifier (URI) that uniquely identifies the associated Confluent resource and is prefixed with `crn://`. In the CRN: ```text crn://confluent.cloud/organization=fc5ba16d-661d-474c-85df-c2a1ed26032c/environment=env-pqr45/cloud-cluster=lkc-a1b2c/kafka=lkc-a1b2c ``` Interpret the content as follows: - An authorization event occurred in Kafka cluster `kafka=lkc-a1b2c`. - The Kafka cluster is in the environment `environment=env-pqr45`. - The environment is in the organization `organization=fc5ba16d-661d-474c-85df-c2a1ed26032c`. ## CRN examples The following CRNs identify some of the most commonly-used Confluent Cloud resources. Cluster Resource CRN : This CRN identifies the Kafka cluster.
Example:
```text crn://confluent.cloud/organization=9bb441c4-edef-46ac-8a41-c49e44a3fd9a/environment=env-456xy/cloud-cluster=lkc-123abc/kafka=lkc-123abc ``` Topic CRN : This CRN identifies Confluent Cloud topics.
Example:
```text crn://confluent.cloud/organization=9bb441c4-edef-46ac-8a41-c49e44a3fd9a/environment=env-456xy/cloud-cluster=lkc-123abc/kafka=lkc-123abc/topic=my_kafka_topic ``` Service Account CRN : This CRN identifies Confluent Cloud service accounts.
Example:
```text crn://confluent.cloud/organization=9bb441c4-edef-46ac-8a41-c49e44a3fd9a/service-account=sa-abc1234 ``` Schema Registry CRN : This CRN identifies a Confluent Cloud Schema Registry.
Example:
```text crn://confluent.cloud/organization=9bb441c4-edef-46ac-8a41-c49e44a3fd9a/environment=env-456xy/schema-registry=lsrc-789qw ``` ## Related content * [Confluent Resource Names (CRNs) in Confluent Cloud APIs](https://docs.confluent.io/cloud/current/api.html/#confluent-resource-names-crns) * [Confluent Resource Names](/platform/current/security/audit-logs/audit-logs-concepts.html#confluent-resource-name-crn)
