## Overview

The Address entity stores shipping and billing addresses for customers, orders, and payments. It supports address validation, geocoding, and delivery instructions to ensure accurate order fulfillment.

### Entity Properties

<EntityPropertiesTable />

## Relationships

- **Customer:** An address can belong to one `Customer` (identified by `customerId`).
- **Order:** An address can be used by multiple `Order` entities for shipping.
- **Payment:** An address can be used by multiple `Payment` entities for billing.

## Address Types

- **Billing:** Used for payment processing and invoicing
- **Shipping:** Used for order delivery
- **Both:** Can be used for both billing and shipping

## Examples

- **Address #1:** John Doe's home address - default shipping and billing address.
- **Address #2:** Corporate office address - billing only, validated with high confidence.
- **Address #3:** Gift recipient address - shipping only, with special delivery instructions.

## Business Rules

- Each customer can have only one default address per type
- Addresses must be validated before being marked as default
- International addresses require country-specific validation
- Geocoordinates are automatically populated when available
- Address changes should create new versions for audit trail
- PO Box addresses may have shipping restrictions
- Address validation improves delivery success rates
