# Exact Postal Code Matching

## Exact Postal Code Matching Method

Exact postal code matching method checks if the customer's location is eligible for local delivery by checking exactly the postal code/zip code that he put in the widget

{% hint style="success" %}
This approach should be used if your delivery area is limited to **a few postal/zip codes**. In case you deliver to a large number of eligible postal codes, our [Partial matching method](broken://pages/NOgnHzez1gv3IXa6Fz0G) may be a better option
{% endhint %}

## How Does The Exact Postal Code Matching Method Work?

You will need to **enter at least a valid exact postal code** to enable delivery zone

Your customers will need to enter their postal/zip codes in the widget to check if delivery is available

If the postal code exactly matches one of the postal codes/zip codes that you define in your delivery conditions setting, the customer will be able to proceed

If the postal code does not match any postal code/zip code that you set on your back end, the consumer will be unable to proceed further
