What is a CP575?

The CP575 is the confirmation letter that you get from the IRS when you obtain an Employer Identification Number – EIN or “Tax ID #” for a business. To enroll with Medicare, you must provide a copy of this letter as proof of the legal name of the business. If you do not have the original CP575, then you can request a replacement letter 147C to verify your EIN. These two documents are generally the only documents that Medicare accepts as proof of your EIN. To request a replacement letter 147C you can call the IRS business center at 800.829.4933. The hours of operation are 7:00 a.m. – 7:00 p.m. EST, Monday – Friday.
