# Local delivery validation methods

# Local delivery validation methods

Choose how DingDoong checks whether a customer's address is eligible for local delivery. There are five methods — pick the one that matches how you actually deliver.

|| Available on all plans.



## Overview

Validation runs when a customer enters their address (or postal code) in the widget. If their location is eligible, they can pick a delivery date; if not, they're told delivery isn't available. You set the method in **General settings → Local delivery validation**, and can refine it per delivery zone.

|| Changing the validation method doesn't affect existing orders — it only changes how new customers are checked.



## Before you start

* Local delivery is enabled on at least one location — see [How to enable local delivery](#).



## The five validation methods

| Method | Best for | How it checks |
| ---- |
| **No validation** | Deliver everywhere; no address check | Customer just picks a date |
| **Postal/ZIP code** | Fixed list of neighborhoods | Matches the postal code the customer enters |
| **Radius (distance)** | "Within X miles/km of my store" | Measures distance from your location to the address |
| **State / City** | Deliver to certain states or cities | Matches the customer's state/city |
| **Country** | Deliver to certain countries | Matches the customer's country |



## How to choose a validation method

### Step 3: Configure the method

* **Postal code** — add eligible codes (exact or partial). See [Exact postal code matching](#) and [Partial postal code matching](#).
* **Radius** — set the maximum distance and unit (km or mi) from your location.
* **State/City or Country** — add the eligible states/cities or countries.

## How it looks on the storefront

With validation on, customers enter their address/postal code and see whether delivery is available before choosing a date. With **No validation**, they go straight to date selection.

## Common scenarios

### Bakery delivering within 10 miles

Use **Radius**, set 10 mi from your store.

### Florist serving a few postal codes

Use **Postal/ZIP code** with exact matching.

### Regional store shipping to select states

Use **State/City**.



## Tips & Best practices

|| Radius validation needs an accurate store address and (for the map) a Google Maps API key — see [Google Maps API](https://help.omegatheme.com/en/article/google-maps-api-uptdxe/).

| If you deliver to many postal codes, use [Partial postal code matching](#) instead of entering each code.



## Troubleshooting

### Valid addresses are rejected?

Your zone is too narrow or the method doesn't match your real area. Widen the radius / add the missing codes / switch methods.

### Radius isn't measuring correctly?

Confirm your location's address is exact and your Google Maps API key is valid.



## FAQ

### Can I use different methods per zone/location?

Yes — refine validation per delivery zone after picking the base method.

### How do I switch back to no checking?

Choose **No validation** and save.
