Tax ID Guide - Format & Restrictions

This article will consolidate relevant Tax ID information for e-commerce merchants. 

What is a Tax ID?

A Tax ID in shipping is a general term used to describe a combination of numbers that identify specific citizens in countries requiring identification for customs screening purposes. There may be variations in phrasing depending on the destination country. Some Asian countries refer to the number as a TIN (China, Taiwan, South Korea). In Brazil, on the other hand, the tax ID is referred to as a CPF number.

Couriers may require a customer's Tax ID to be provided upon shipment creation to ensure smooth customs clearance when shipping to certain countries. Failure to provide a Tax ID for certain countries may lead to issues at customs resulting in return or abandonment. 

Why is a Tax ID Important?

  • Decreases transit time: By providing all information necessary for import, you will speed up the clearance process at customs. 
  • Reduce returns: Many shipments return due to a missing tax ID and an unresponsive recipient. Adding a tax ID increases the chances of successful delivery.
