• Opening a business bank account at local institutions like Citizens Bank of Las Cruces
• Applying for city or county business licenses and permits
• Establishing business credit for expansion and investment

Without an EIN, many business transactions in Doña Ana County simply aren’t possible. Let’s explore how to get an EIN number efficiently, with a focus on local nuances.
