Overview

Addresses store shipping and billing information for customers. Each address can be marked as default and associated with subscriptions for fulfillment.

How It Works

Create an address - Add a shipping or billing address for a customer
Set as default - Mark an address as the customer's default
Use for fulfillment - Associate addresses with subscriptions for shipping

Example: A customer adds their home address for magazine delivery. Later, they add a work address and set it as default for future subscriptions.

API Endpoints

Method	Endpoint	Description
`GET`	`/api/v1/core/addresses`	List all addresses
`POST`	`/api/v1/core/addresses`	Create an address

Important Behaviors

Soft delete: Addresses are soft-deleted, not permanently removed.
String cleansing: Address fields are automatically cleaned — patterns removed, whitespace trimmed, trailing commas stripped, empty values nullified.
Subscription update: When an address is updated, a background job can update the default shipping address on the customer's subscriptions.
AvaTax validation: If the AvaTax integration is enabled, address validation is available via a feature flag.
