There is no public source to use to find a company’s EIN. Your company is required to provide the EIN on your W2.
You should always enter your wage information from your W2 and not from your pay stub. This reduces the chances that you will need to amend your tax return because of incomplete or missing information.
The link below lists the companies partnered with Turbo Tax where you can download your W2 directly.

Your employer has until January 31 to mail your W2. You can call and ask what their EIN is, but they are not required to give that information out over the phone. Many companies view their EIN the same way individuals view their social security numbers and are reluctant to share that information.
The IRS recommends waiting until February 14 before taking any action if you have not received your W2. If it's after February 14 with no help or response from your employer, the IRS can assist you at 800-829-1040.
