# Change Address in the US and Exclude from NCOA

**LFS version**: requires v12.46 or later

**Context**

In the United States, organisations get notified through NCOA (National Change of Address) updates when a subscriber changes their address. However, not all address changes are valid, so it's important to identify and flag these addresses to prevent incorrect updates.

For customer service representatives, having the ability to exclude NCOA updates for address changes within the US is crucial for complying with national regulations.

When helping a customer change their address, if the address is in the US, there is an option to exclude NCOA updates.

The checkbox to exclude NCOA updates is always unchecked by default.

**Considerations**

Since this feature is optional, it has been developed as a separate flow component that can be added to the delivery address screen when needed.

To ensure that the toggle is visible only when updating a delivery address or both billing and delivery addresses, and hidden for updates to the billing address only, utilise the Component Visibility setting in the flow builder:

When submitting an address update, the 'exclude\_ncoa' boolean flag is included in the address attribute of the request payload:
