Learn More About ISO3 Country Code
Overview
When tracking an international shipment shipped by a postal service (Airmail / Registered Mail / EMS) in AfterShip, you could specify the destination country and track at both Origin and Destination country. Postal services usually refer to the government owned carrier for each country - USPS for the States, Australia Post for Australia for example. You can specify the destination country when using CSV upload or API in AfterShip.
How it works
By including the destination country, AfterShip can detect and display tracking data from both the origin and destination postal carriers—improving the accuracy and coverage of international shipment updates.
Ways to specify destination country
1. CSV Upload
When uploading shipments via CSV, include the destination_country field and input the appropriate ISO Alpha-2 country code (e.g., US for United States, AU for Australia).
2. API Integration
Use the destination_country_iso3 parameter when creating or updating tracking entries via the AfterShip API. This ensures AfterShip attempts to track the shipment through both postal services.
Key takeaways
- Specify the destination country for international postal shipments to receive tracking updates from both origin and destination carriers.
- You can add the destination country via CSV upload or API integration.
- This is particularly useful for shipments handled by government postal services like USPS or Australia Post.
