Capturing a slice of the US retail market is a common objective for many Australian businesses. Platforms like Shopify, supported by tech businesses like Facebook and Google, has made it easier than ever to enter overseas markets like the US.

Australian entrepreneurs can now live this dream. However, if you are selling in the US, you may need an Employer Identification Number (EIN) which is used to identify a business entity. Australian’s do not have an Social Security Number (SSN) which makes this process slightly more complicated.

Will I need an EIN?

If you are a selling through your own website using a platform like Shopify platform, the short answer is yes.

How to apply for an EIN

Australians are not able to apply online if their business isn’t incorporated in the United States. As stated by the IRS, “If you were incorporated outside of the United States or the U.S. territories, you cannot apply for an EIN online.”

As an Australian, you will have to fill out an IRS Form SS-4 – Application for Employer Identification Number providing an American business address and choose only ONE of the following methods:

  • Phone (immediately): Applications for EIN by phone can only be received by international applicants. As stated on the IRS instructions for form SS-4: “If you have NO legal residence, principal place of business, or principal office or agency in the U.S. or U.S. possessions, you may call 267-941-1099 (not a toll-free number), 6:00am – 11:00pm (ET), Monday-Friday, to obtain an EIN.”
  • Fax (4 business days): Send the IRS form to this fax number: (859) 669-5987.
  • Mail ( A few weeks): Mailing your SS-4 form will be the slowest method in receiving your EIN, however if you do decide to choose this method you can email the SS-4 for for an EIN to:
