# Upgrade A2P Campaign from Sole Proprietor to Business

If you’d like to upgrade your A2P campaign from a Sole Proprietor brand to a Business brand, we can assist you with the process. A Business brand allows you to register and use multiple phone numbers for sending messages, unlike a Sole Proprietor brand, which is limited to one number.

**Please keep the following in mind before proceeding:**

1.  **Business registration:** Your business must have been registered for at least **15 days**. Submitting before this period may result in a failed registration.
    

2.  **Downtime:** There may be some downtime during the transition because we’ll need to resubmit your A2P campaign and delete the currently approved Sole Proprietor brand.
    
3.  **Resubmission fee:** An additional $24 charge will apply for the A2P resubmission.  
    

# How to Get an EIN

There is **no fee to apply for an EIN**.

You can apply for an EIN through the official IRS website:  
[IRS – Employer Identification Number](https://www.irs.gov/businesses/employer-identification-number?utm_source=chatgpt.com)

Once you receive your EIN, please allow approximately **15 days** for your business information to update across verification systems.

Please send us your **EIN, business name, and business address**. These details should match the information on your **SS-4 document from the IRS**.

Support Team will then submit your A2P registration as a **Business**. Once your A2P registration is verified, you’ll receive a notification from us, and you can start purchasing **multiple phone numbers** for your account.

If you’re okay with these requirements and would like to proceed, please let us know. Thank you!
