# Identifiers
|
|
All objects in the Kubernetes REST API are identified by a Name and a UID.
|
|
|
|
## Names
|
|
Names are user-provided. Only one object of a given kind can have a given name at a time. But if you delete an object, you can make a new object with the same name. Names are the used to refer to an object in a resource URL, such as `/api/v1beta3/pods/some.name`. Names may be up to maximum length of 253 characters and consist of lower case alphanumeric characters, `-`, and `.`. See the [identifiers design doc](design/identifiers.md) for the precise syntax rules for names.

## UIDs

UID are generated by Kubernetes. Every object created over the whole lifetime of a Kubernetes cluster has a distinct UID.
