What is EIN?
An EIN (Employer Identification Number) is the IRS's ID number for a business — like a Social Security number for your company. You need one to hire employees, open a business bank account, or file certain tax returns. It's free from the IRS and takes minutes online; never pay a third party for one.
In practice
A new LLC applies for an EIN on irs.gov, gets it instantly, and uses it to open a business checking account the same week.

Do I need an EIN as a freelancer?
Not necessarily — sole proprietors can use their SSN. But an EIN lets you keep your SSN off W-9s and is required if you hire anyone.
How do I get an EIN?
Apply free on irs.gov — it takes minutes and the number is issued immediately. Never pay a third-party service for this.
Is my EIN sensitive information?
Less sensitive than an SSN, but still treat it carefully — it appears on W-9s and tax filings. Share it with clients and banks, not the public.
