Unfortunately, you cannot get a copy of the IRS EIN confirmation letter online.

Sole proprietorships and single-member LLCs may use Social Security numbers as their business' tax ID number. The terms “corporate number” and “EIN” can be used interchangeably.

Unfortunately, looking up your EIN on IRS.gov isn't an option, as there's no EIN lookup tool. Still, that doesn't mean you're entirely out of luck. You can find it on the official IRS notice you received when it was issued, call the IRS directly or locate your EIN on business documents.

Find a previously filed tax return for your existing entity (if you have filed a return) for which you have your lost or misplaced EIN. Your previously filed return should be notated with your EIN. Ask the IRS to search for your EIN by calling the Business & Specialty Tax Line at 800-829-4933.

An Employer Identification Number (EIN) is a nine-digit number that IRS assigns in the following format: XX-X. It is used to identify the tax accounts of em- ployers and certain others who have no employees. However, for employee plans, an alpha (for example, P) or the plan number (e.g., 003) may follow the EIN.
