# How to Find Your LLC Registration Number and Business Tax ID
To create a professional account on Paxum, you will need to provide specific information regarding your LLC, including the "Registration Number" and "Business Tax ID." Here’s how you can find this information:
## Finding Your Registration Number
The registration number for your LLC can typically be found at the top of your formation document. This document is usually provided when you initially register your business with the state. If you cannot locate it, consider checking any official correspondence you received during the formation process.
## Understanding Your Business Tax ID
Your Business Tax ID is commonly referred to as your Employer Identification Number (EIN). This number is assigned by the Internal Revenue Service (IRS) and is used for tax purposes. You can find your EIN on the EIN confirmation letter that you received from the IRS when you applied for it. If you do not have this letter, you may also find your EIN on your business tax returns or other official documents related to your business.
## Summary
- **Registration Number**: Located at the top of your LLC formation document.
- **Business Tax ID (EIN)**: Found on your EIN confirmation letter from the IRS or on your business tax returns.
If you have further questions or need assistance, consider reaching out to your business formation service or the IRS for more detailed guidance.
