# ID field

This is a specific field for generating an ID.

#### ID strategy

Go to the [advanced options tab](/meta-fields/the-meta-fields-manager/advanced-options-fields-settings.md) and select between:

* UUID v1 (default)
* UUID v4
* UUID v7
* ULID
* Auto-increment
* Random int

#### Generate the ID

The ID will be made automatically in the editor based on the strategy that was picked.

If you need to regenerate it, just click on the link button below:

#### Bulk generation

If you have at least one ID field associated with a custom post type, navigate to the post type list.

You'll find a new option for bulk actions:

And then select the posts to generate IDs.
