# PhysicalResourceIdContextKeyValuePair
<a name="API_PhysicalResourceIdContextKeyValuePair"></a>

Context information that enables CloudFormation to uniquely identify a resource. CloudFormation uses context key-value pairs in cases where a resource's logical and physical IDs aren't enough to uniquely identify that resource.
