# Shipping Address Edits
#### What is Shipping Address Edits?
Shipping Address Edits allows customers to update their shipping address after placing an order while maintaining accuracy and deliverability. The system performs real-time verification using postal databases (USPS, Australia Post, Royal Mail, and more) and provides validation suggestions to prevent undeliverable orders.
**Key features:**
* Real-time address validation
* Country restriction options
* Automatic shipping cost recalculation
* PO Box controls
* Validation sensitivity settings
***
### Configuration
#### How to Access Settings
1. Navigate to **Order Editing** > **App Blocks**
2. Select **Shipping Address Edits**
***
### Step 1: Enable Address Editing
**Allow Customers to Edit Their Shipping Address**
* Toggle **ON** to enable address editing
* Customers can update shipping details during the editing period
**Allow Customers to Use PO Boxes for Shipping**
* Toggle **ON** to permit PO Box addresses
* Toggle **OFF** if your carrier doesn't deliver to PO Boxes
**Limit Shipping Edits to the Original Shipping Country (Optional)**
* Toggle **ON** to prevent country changes
* Example: Order placed with US address can only be changed to another US address
* **When to use:** If shipping costs and tax rates vary significantly by country
***
### Step 2: Set Address Validation Sensitivity
Choose how strict address validation should be:
#### **Option 1: All Suggestions**
**What it validates:**
* Typos in street names
* Missing apartment numbers
* Incorrect street suffixes (e.g., "Rd" instead of "Pl")
* Address formatting issues
**Customer experience:** More prompts and suggestions for minor issues
**Best for:** Merchants who want maximum address accuracy
#### **Option 2: Critical Only (Recommended)**
**What it validates:**
* Undeliverable addresses
* Invalid or unknown locations
* Critical errors that prevent delivery
**Customer experience:** Minimal friction, only alerts for serious issues
**Best for:** Most merchants—balances accuracy with customer experience
***
#### Step 3: Configure Advanced Features (Optional)
**Validate Addresses Using USPS CASS Formatting**
**What it does:** Converts addresses to USPS CASS format to ensure proper delivery and standardizes formatting across Google Maps, USPS, and Shopify
**When to enable:** US-based merchants who want maximum USPS compatibility
***
**Recalculate Shipping Costs When Address Changed**
**What it does:** If an address change increases shipping cost, customer must pay the difference before the change is applied
**When to enable:** When shipping costs vary by location (urban vs. rural, different states, etc.)
**Customer experience:** Customer sees new shipping cost, must confirm and pay difference to proceed
***
**Prioritize Apartment Number in Address Formatting**
**What it does:** Formats addresses to display apartment numbers first
**Example:**
* Standard: 100 Shopify Rd, Apt 2
* With this enabled: Apt 2, 100 Shopify Rd
**When to enable:** If your carrier or warehouse prefers apartment numbers first
***
### Address Validation Providers
Order Editing uses government and postal databases for validation:
* **United States:** USPS
* **Australia:** Australia Post
* **New Zealand:** Google Maps
* **United Kingdom:** Government data
* **Rest of World:** Government data
**Why this matters:** Ensures compatibility with Shopify's native address system and carrier requirements
***
### Customer Experience
#### Real-Time Address Validation
**What customers see:**
1. Customer changes shipping address during editing window
2. System validates address in real-time
3. **If issues detected:**
* Validation prompt appears immediately
* Suggested corrections shown
* Customer can accept suggestion or proceed with original entry
**Common validations:**
* Missing apartment numbers
* Incorrect postal codes
* Invalid addresses
* Typos in street names
***
#### Country Restriction (If Enabled)
**What customers see:**
If "Limit to Original Shipping Country" is enabled:
* Customer can only enter addresses in the same country as original order
* Attempting to change country shows error message
* Must contact support for international address changes
***
#### Shipping Cost Adjustments (If Enabled)
**What happens when address increases shipping cost:**
1. Customer enters new address
2. System calculates new shipping cost
3. **If cost increases:**
* Customer sees additional charge
* Must confirm and pay difference
* Payment processed before address updates
4. **If customer doesn't pay:**
* Original shipping address remains unchanged
* Order proceeds with original address
**Example:**
* Original address: Downtown LA (Standard shipping: $5)
* New address: Rural Montana (Standard shipping: $15)
* Customer must pay $10 difference to update address
*Make sure this setting*[ *Shipping Cost Recalculations*](/oe-help-book/onboard/getting-started-with-order-editing/start-finish-onboard-guide/settings-configuration/shipping-cost-recalculations.md) *is configured*
***
### Best Practices
**Enable real-time validation** to reduce shipping errors and fulfillment issues
**Use "Critical" mode** for improved accuracy with minimal customer friction
**Restrict international address changes** if shipping costs and tax rates vary significantly
**Enable automatic shipping cost recalculations** to prevent unexpected fees for your business
**Allow PO Boxes** unless your carrier specifically prohibits them
**Test address validation** with various address types (apartments, rural, PO Boxes) before going live
***
### Troubleshooting
**Validation not appearing:** Verify address validation is enabled and sensitivity is set
**Too many validation prompts:** Switch from "All Suggestions" to "Critical Only"
**Customer can't change country:** Check if "Limit to Original Country" is enabled
**Shipping costs not recalculating:** Verify "Recalculate Shipping Costs" is enabled and Shipping Cost Recalculations is ON in main Settings
**PO Box rejected:** Check if "Allow PO Boxes" setting is enabled
