Steps
Confirm the principal place of business is in the US or a US territory and gather the responsible party's SSN or ITIN
Go to the IRS 'Apply for an Employer Identification Number (EIN) Online' page and launch the EIN Assistant interview
Complete the application in a single session, since it cannot be saved and times out after 15 minutes of inactivity
Submit the completed interview to receive the EIN immediately once the application validates
Download and retain the confirmation notice before closing the browser, since it cannot be regenerated from the online tool later
Known gotchas
Only one EIN can be issued per responsible party per calendar day through this tool
The tool is only available during specific windows in US Eastern Time on a weekday/weekend schedule that IRS.gov can change, so re-verify current hours rather than assuming a fixed schedule
There is no API for this; it is a browser-based interactive session, so automation must drive the web form rather than call a REST endpoint
