Ask HN: Can a foreign company have an US Tax ID?

Yes. I am not a tax professional, but my understanding is that business entities operating in the US are required to have a business tax ID number, called an Employer Identification Number (EIN).

You may find better and more detailed answers at these links to the US Internal Revenue Service (IRS)...

Yes. You need to incorporate in US and file for an Federal Employee ID Number.
