What is an EIN?

An Employer Identification Number (EIN) is a unique nine-digit tax identification number assigned by the IRS to business entities operating in the United States. It's essentially a Social Security number for your business. While not always legally required, it simplifies many business processes.

How to Apply for an EIN

  1. Determine Your Eligibility: Ensure your mobile developer business entity (LLC, S-Corp, etc.) is properly formed and recognized in Delaware. You must have a legitimate business purpose to obtain an EIN.
  2. Choose Your Application Method: You can apply for an EIN online through the IRS website, by mail (Form SS-4), or by fax. The online application is the fastest and most convenient method.
  3. Complete the EIN Application (Form SS-4): Accurately fill out Form SS-4, providing information about your mobile developer business, including its legal name, address, responsible party (owner, member, or officer), and the nature of your business activities.
  4. Submit Your Application: If applying online, submit the completed application through the IRS website. If applying by mail or fax, send Form SS-4 to the appropriate IRS address or fax number listed on the form.
  5. Receive Your EIN: If applying online, you'll typically receive your EIN immediately after submitting the application. If applying by mail or fax, it may take several weeks to receive your EIN.
  6. Verify Your EIN: After receiving your EIN, verify its accuracy by checking the IRS confirmation notice. Ensure all information matches your Delaware business formation documents.
