Shipping label customizations allow merchants to change the values printed on their return shipping labels. These custom values ensure that warehouse teams have the necessary information available on labels to look up and process returns quickly.

This article explains how shipping label customizations work, how to set them up, and customization options for different carriers.

Note: This feature is available on all Loop plans for admins who are using Ship by Loop and EasyPost for shipping label generation. If generating return shipping labels through a different shipping provider, please contact support@loopreturns.com.

Custom values, such as Return ID or Order ID, are usually added to shipping labels to help with processing returns sent back to the warehouse. This gives operations teams the necessary information to look up and process returns quickly. For example, Return IDs (or RMA) on the label can be included on the shipping label or manifested as a barcode that the warehouse team can scan.

1. In the Loop admin, go to Settings > Shipping.

2. Under Shipping Services, click Manage Integration next to Ship by Loop or EasyPost.

   

3. Under Available Carriers, find the carrier that needs label customizations and click Edit carrier.
   

   

4. In the Label Customization section, edit the fields for that carrier.

   Important: If the Label Customization section does not show in the Loop admin, please reach out to the merchant's Merchant Success Manager or support@loopreturns.com.
   
   

   

5. Under each field, choose the value from the dropdown and, if needed, attach a prefix or suffix to the value. Please review the chart in the next section for these value definitions.

   Note: The customizable fields available will vary by carrier. Please refer to the Label Customization Options by Carrier section below for more information about specific carriers.
   
   

   

6. If selecting the Custom Text value, enter the custom text into the new field that appears.
   

   

7. Depending on the carrier, there may also be the option to show the value as a barcode on the label.
   
   

   

8. After making the appropriate changes, click Save at the top of the screen before exiting.
   
   

   

Note: Hazardous material (HazMat) values, definitions, and examples are accessible in Loop's separate HazMat article.

The fields available for customizations on labels will vary by carrier. Please review which custom fields are supported by each carrier below.

USPS's bulleted fields below support all values in the Value definitions chart. Their default values are:

• Print Custom 1 default: Order Name

• Print Custom 2 default: Return Outcomes

• Print Custom 3 default: None

• Invoice Number default: Order Name

USPS also has a HazMat field supporting:

• Default: Blank

• Many other values listed in Loop's HazMat article

Please review the USPS HazMat article for more information on HazMat shipping labels.

Note: USPS on EasyPost does not support rendering barcodes on the label.

FedEx's bulleted fields below support all values in the Value definitions chart. Their default values are:

• REF default: Order Name

• RMA default: None

• PO default: None

• Invoice Number default: Order Name

FedEx supports rendering a barcode for the RMA field, but no other fields.

Important: In order for the RMA to render as a barcode for FedEx labels, Loop must enable backend settings to mark the label as a Return Label. This may affect label rates for FedEx as well as other carriers. It is best to check with the carrier's account reps before Loop enables this to ensure that rates will not increase drastically if labels are marked as Return Labels. Please contact the merchant's Onboarding Specialist or support@loopreturns.com for additional questions.
