# Address Link Table Integration Guide

This framework enables consistent address resolution by linking equivalent records across systems into a single source of truth.

The linkage system supports both **batch processing** and **real-time lookup**, ensuring flexibility and scalability for various integration scenarios.

> **Initial Implementation:**\
> The first implementation of this framework is tailored for the **New Zealand (NZ) locale**, with support for additional locales planned in future releases.

#### **Key Capabilities**

* Consolidates address records from multiple sources into a unified link table.
* Supports batch processing for large-scale linkage.
* Performs consolidated lookups by retrieving and merging address records from multiple sources using the link table.
* Enables real-time linkage during address lookup if no match is found in the link table.
* Designed for extensibility across locales.

#### **Key Benefits**

* Consolidates results from multiple sources into a single, unified candidate list.
* Reduces duplication and improves match accuracy.
* Supports fallback to online linkage when no pre-existing link is found.
