# How do I add additional information to my customer’s billing/shipping address?

Sometimes, you might wish to add a few extra information to your customer’s billing/shipping address. It could be anything from VAT Number, a reference number, or a tracking ID.

You can use custom fields to enter these additional information and add them to your customer’s billing/shipping address by inserting the appropriate placeholders.

To do that,

*   Click on the **Gear** icon on the top-right corner.
*   Go to **Preferences** and click on **Contacts**
*   Add custom fields of your choice and click **Save**.
*   Now, head to the **Customer Billing Address format** or **Customer Shipping Address format** and click on the **Insert Placeholder** drop-down.
*   Choose the appropriate custom field label and custom field value.
*   Once done, click **Save** for the changes to take effect.
