Where to mail form 41

Form 41, also known as the "Application for Employer Identification Number (EIN)", is typically mailed to the following address:

Internal Revenue Service Attn: EIN Operation 1111 Constitution Ave NW Washington, DC 20224-0002

However, it's recommended to check the IRS website for the most up-to-date mailing address, as it may change over time. You can also apply for an EIN online through the IRS website, which is a faster and more convenient option.

Additionally, you can also fax the form to the IRS at (855) 641-6935 or submit it electronically through the IRS website.

It's important to note that you should keep a copy of the form and any supporting documents for your records.
