# Metadata API Example

To create a custom address field on an object, use Metadata API.

**note:** Before you create a custom address field, review the [Custom Address Fields Requirements and Limitations](https://developer.salesforce.com/docs/platform/caf-dev/guide/caf-dev-limitations.md). To discuss the feature and ask questions, join the [Custom Address Fields Discussion](https://trailhead.salesforce.com/trailblazer-community/groups/0F94S000000H3KISA0) group on the Trailblazer Community.

This example creates a custom object of type Address on the Account object.

```xml
<?xml version="1.0" encoding="UTF-8"?>
<CustomObject xmlns="http://soap.sforce.com/2006/04/metadata">       
    <fields>
        <fullName>MailingAddress__c</fullName>
        <externalId>false</externalId>
        <label>Mailing Address</label>
        <required>false</required>
        <type>Address</type>
        <unique>false</unique>
   </fields>
 </CustomObject>
```
