Do suppliers require a tax ID?
A Sales Tax ID (also called a Resale Certificate) is a number issued by your state or local government that allows you to charge and collect sales tax from buyers in your region—even if you’re selling online.
At first, it might sound complicated, but it’s just part of the process of setting up a legitimate eCommerce business. While most suppliers don’t require a Sales Tax ID to work with you, having one can unlock additional benefits, such as access to exclusive wholesale pricing.

If you are serious about establishing an eCommerce business, in most US states, you'll need a Sales Tax ID.
If you live outside of the US and the supplier requires a Sales Tax ID, you can provide the supplier with the closest equivalent to a Sales Tax ID for your country.
For example, if you live in the UK or the EU, you will need to be a VAT registered trader so in place of a Sales Tax ID use your VAT ID. In Australia and New Zealand, you can use your GST number.
Alternatively, the wholesaler may want to see your business license/registration details. Below are guides to help you register your business:
