EIN for Mexican Entrepreneurs
Apply for a US EIN from Mexico without an SSN. ein.so handles the IRS fax filing for Mexican cross-border sellers, importers, and e-commerce businesses. $49 Standard. $97 Express.
Mexican entrepreneurs can get a US EIN by faxing IRS Form SS-4 with their Mexican passport number. No SSN, ITIN, or US visa is required. Mexico and the US share the world's busiest border and billions of dollars in daily trade. Whether you are expanding cross-border commerce or launching on Amazon.com, ein.so handles the EIN application for $49 (Standard) or $97 (Express).
The Scale of US-Mexico Trade
Mexico has a population of 130 million, a GDP of $1.3 trillion, and bilateral trade with the US exceeding $800 billion annually -- making Mexico the United States' largest trading partner as of 2023. Over 1 million US companies import from or export to Mexico. The MXN/USD exchange rate trades near 17. USMCA trade benefits, geographic proximity, and time zone alignment create natural advantages for Mexican entrepreneurs. A US EIN is the foundation for formalizing these cross-border business activities.

Application Process
How Do Mexican Citizens Apply for a US EIN?
Mexican applicants receive their EIN in 4-7 business days via fax, with a 97% first-submission success rate through ein.so. Mexico shares time zones with the US (CST/MST/PST overlap), making phone calls feasible but still unreliable due to 1-2 hour hold times. Here is the process:
Step-by-Step EIN Filing From Mexico
Form a US LLC
Gather Your Documents
Apply Through ein.so
Receive Your EIN
Why Fax Is More Reliable Than Phone
Mexico's time zone alignment with the US is an advantage for phone applications, but IRS hold times remain long and unreliable. ein.so provides a guaranteed, hassle-free process. See our SS-4 form guide for details.
| Document | What to Prepare | Notes |
|---|---|---|
| Mexican Passport (Pasaporte) | Valid, unexpired passport | Passport number in foreign ID field; not CURP, INE, or RFC |
| US LLC Documents | Articles of Organization, entity name, state | Wyoming, Delaware, or New Mexico most common |
| Mexican Address | Calle, numero, colonia, CP, ciudad, estado | ein.so reformats Mexican addresses for IRS acceptance |
| Registered Agent | US registered agent name and address | Provides US business address for IRS |
| Business Activity | Brief description of US business | E.g., "cross-border trade," "e-commerce," "real estate" |
Comparison
RFC vs EIN: What Mexican Entrepreneurs Need to Know
Mexico's RFC is issued by SAT and is required for all Mexican tax obligations, while the US EIN is issued by the IRS for US federal tax purposes. Mexican entrepreneurs operating cross-border need both. Here is how they compare:
RFC vs EIN: Key Differences
| Feature | Mexican RFC | US EIN |
|---|---|---|
| Issuing Authority | SAT (Mexico) | IRS (United States) |
| Purpose | Mexican tax identification | US federal tax identification |
| Format | 13 characters (individuals) or 12 (companies) | 9 digits (XX-XXXXXXX) |
| US Banking | Not accepted | Required for US bank accounts |
| Amazon.com | Not sufficient for US seller registration | Completes tax interview |
You need both your RFC (for Mexican obligations) and your EIN (for US obligations) if you operate cross-border. They are complementary, not interchangeable. Learn more about getting an EIN without an SSN.
Banking
How Do Mexican Entrepreneurs Manage MXN and USD Banking?
MXN/USD fluctuated between 16.5 and 18.5 over the past 12 months. Mexican banks like BBVA Mexico and Banorte offer USD-denominated accounts domestically, and a US bank account via your EIN adds a second USD tier with full ACH capability. Here is how Mexican entrepreneurs structure their finances:
Dual-Currency Banking for Cross-Border Sellers
US Bank Account
Mexican USD Account
Wise Transfers
Cross-Border Payment Processing
Border-city entrepreneurs in Tijuana, Ciudad Juarez, Nogales, and other border cities have the added advantage of being able to visit US banks in person. But even from Mexico City, Monterrey, or Guadalajara, you can open a US bank account remotely with your EIN. Learn more about EIN for banking. Apply for your EIN now.
Tax Considerations
What Tax Obligations Do Mexican EIN Holders Need to Consider?
Mexico's corporate tax rate is 30% flat, compared to the US federal rate of 21%. The Mexico-US tax treaty prevents double taxation, and Mexico offers a RESICO regime with rates as low as 1% for qualifying small businesses earning under MXN 3.5 million. Key considerations:
SAT and IRS Dual Filing Requirements
US Tax Filing
Mexico-US Tax Treaty
SAT Obligations
ein.so handles the EIN application. Tax compliance is best managed with a Mexican contador (accountant) who understands cross-border US-Mexico obligations. Your EIN is the starting point for US compliance. Visit EIN for non-residents for more.

Can I call the IRS from Mexico to get an EIN?
Yes, Mexicans can call the IRS at 267-941-1099. Mexico shares similar time zones with the US, making phone calls feasible. However, hold times often exceed 60 minutes, and you may need multiple attempts. The fax method through ein.so is faster and more reliable for $49.
What is the difference between an RFC and a US EIN?
Your RFC (Registro Federal de Contribuyentes) is issued by the SAT (Servicio de Administracion Tributaria) for Mexican tax purposes. A US EIN is issued by the IRS for US tax purposes. They serve different countries. Your RFC cannot be used for US banking, tax filing, or marketplace registration.
Does USMCA affect my need for a US EIN?
USMCA (United States-Mexico-Canada Agreement) facilitates trade between the three countries but does not eliminate the need for a US EIN. If you sell into the US market, have a US entity, or have US tax obligations, you need an EIN regardless of USMCA benefits.
Can I sell on Amazon.com from Mexico with a US EIN?
Yes. Many Mexican sellers expand from Amazon.com.mx to Amazon.com. Your US EIN completes the Amazon tax interview, letting you register as a US-based seller through your LLC. This gives you access to Amazon's US marketplace, FBA warehouses, and the much larger US customer base.
How do I manage MXN and USD with my US EIN?
Open a US bank account using your EIN to hold USD. Use Wise or your Mexican bank's international transfer service to move funds between your US and Mexican accounts. Many Mexican entrepreneurs hold USD earnings and convert to MXN when exchange rates are favorable.
