# Tags

> Add custom tags to locations for flexible grouping

Tags let you add custom labels to locations. Use them in constraints and routing rules to target specific groups of locations.

## How tags work

Tags are free-form labels you create based on your business needs. Unlike types (which are predefined), tags are completely flexible.

**Example tags:**

* Geographic: `east-coast`, `west-coast`, `paris-region`, `uk`
* Capabilities: `heavy-items`, `fragile`, `hazmat`, `engraving`
* Business: `flagship`, `franchise`, `b2b`, `outlet`
* Operations: `high-volume`, `express`, `overflow`

  </Step>

  <Step title="Add tags">
    Type a tag name and press Enter. Repeat for each tag you want to add.
  </Step>

  <Step title="Remove tags">
    Click the **×** next to a tag to remove it.
  </Step>
</Steps>

## Using tags in rules

Once added, you can target locations by tag in your constraints and routing rules.

**Example filters:**

* `Location tag` → `flagship` — rule applies only to flagship locations
* `Location tag` → `east-coast` — rule applies only to east coast locations

<Tip>
  A location can have multiple tags. Rules will match if the location has the specified tag.
