What keeps thousands of online sellers from legally selling in Mexico? It's often the RFC, a tax ID needed by Mexico’s tax authority (SAT). More than 80% of e-commerce businesses aiming at Mexican customers need this ID to follow local laws. Yet, many foreign sellers ignore it until they face fines or blocked transactions.
The RFC is like a business passport for Mexico. It's different from the CURP, which is a national ID for citizens. This tax number shows you're allowed to sell goods or services in Mexico. Without it, platforms like 1688Order won't let you make payments, and SAT audits could stop your business. But, getting your RFC approved is easier than you think—if you know the right steps.
Key Takeaways
- An RFC is mandatory for foreign sellers on Mexican e-commerce platforms.
- SAT requires this tax ID to track business transactions and ensure compliance.
- Unlike CURP IDs, RFCs apply specifically to financial and tax activities.
- Over 4 in 5 online sellers face penalties without proper RFC registration.
- Approved RFCs unlock benefits like smoother cross-border payments and tax deductions.
Understanding the RFC in Mexico
If you're doing business or handling money in Mexico, the RFC number is key. It's like a special ID for taxes. But why is it so important, and who needs it?
What Does RFC Stand For?
The Registro Federal de Contribuyentes (RFC) means Federal Taxpayer Registry. It's like a mix of a Social Security Number and Employer ID in the US. Your RFC has 13 characters, with letters from your name and birth/incorporation date.
Identifier | Purpose | Format |
---|
RFC | Tax operations | 13 characters |
CURP | Civil identification | 18 characters |
Why Is RFC Important?
Without an RFC, you'll face many problems. The SAT needs it for:
- Opening business bank accounts
- Issuing valid tax invoices
- Claiming capital gains exemptions
Not having it can freeze transactions and cost up to $3,500 USD. Even online stores outside Mexico need an RFC for Mexican payments.
Who Needs an RFC?
It's not just for Mexicans. You'll need an RFC if you:
- Hold temporary or permanent residency
- Own property in Mexico
- Sell goods/services through Mexican platforms
Digital nomads and remote workers must also get one. Any income from Mexico needs tax reporting with your RFC. The SAT now watches cross-border deals closely, making registration essential.
The Process of Obtaining Your RFC
Getting your RFC in Mexico is easier than you think. With the right steps and SAT's rules, it's smooth. We'll cover the basics, from getting your documents ready to avoiding mistakes.

Required Documents
First, make sure you have these four important things:
Document | Description | Important Notes |
---|
Printed CURP | Unique Population Registry Code | Retrieve via SAT’s online portal |
Residency Card | Valid immigration document | Non-expired, legible copy |
Passport | Primary ID for foreigners | Include photo and signature pages |
Virtual Queue Token | Appointment confirmation | Obtained through Fila Virtual system |
Steps to Apply for RFC
Here's how to apply in 8 easy steps:
1. Go to the SAT portal and choose “Inscripción en el RFC de Personas Físicas”
2. Get your virtual queue token
3. Upload scanned copies of your documents
4. Use official proof to check your tax address
5. Fill out the digital application form
6. Check everything for mistakes
7. Submit and save your confirmation code
8. Use RFC Mexico consulta tools to check your status
Common Mistakes to Avoid
Many applications fail because of simple mistakes. Here's what to watch out for:
Incomplete CURP: Always get it from the SAT's official tool, not third-party sites.
Address mismatches: Make sure your tax address matches government records.
Translation issues: For RFC Mexico en ingles, use translators approved by Mexican authorities.
Check your documents carefully. Blurred or cropped scans can cause instant rejection. If you need to resubmit, plan ahead.
RFC Mexico for Foreigners
Understanding Mexico's tax system as a foreigner is easier than you think. Whether you're a digital nomad, investor, or part-time resident, knowing about RFC Mexico is important. It helps you stay in line and find financial chances.
Can US Citizens Obtain an RFC?
Yes! US citizens can get an RFC in two ways: tax residency or the non-resident category. Tax residency means you've lived in Mexico for over 183 days. Non-residents apply when they work or earn income in Mexico without being a full resident.
The application process takes 3-6 months through VAT Ai. Corporate applications need business documents. Individual filers need proof of residency.
Unique Requirements for Foreign Applicants
Foreign applicants have three extra steps:
1. Apostilled Documents: Birth certificates, passports, and address proofs must be notarized and have the Hague Apostille stamp.
2. Fiscal Representative: Non-residents need a Mexican tax expert to talk to SAT (Mexico’s tax authority).
3. Dual-Language Submissions: Applications are in Spanish, but SAT accepts English documents with certified translations. This is a key fact many expats miss.
Key Benefits of Having an RFC
Getting an RFC in Mexico does more than follow the law. It helps you fit into the country's digital economy. It's good for freelancers, business owners, and those selling online. This tax ID connects you to both local and global markets.

Tax Compliance Made Effortless
Your RFC makes dealing with Mexico's tax office (SAT) easier. With it, you can:
- File monthly VAT returns online
- Make CFDI 4.0 invoices, which are now required
- Use your e.firma (digital signature) for transactions
This makes paperwork less and cuts down on audit worries. For instance, suppliers need valid CFDI invoices to pay you. Without an RFC, you can't use this easy system.
Access to Business Opportunities
An RFC is more than just for taxes. It opens doors to Mexico's huge $1.6 trillion market. Sites like 1688Order give RFC holders special deals for buying in bulk from China. Here's why it's important:
- Resell items for 6–7 times the cost (e.g., $15 wholesale → $100 retail)
- Follow rules for trading across borders
- Show you're serious to Mexican distributors and buyers
Even those from abroad can benefit. A U.S. seller on 1688Order saw their profits jump 40% each month. This was after getting an RFC, which let them ship directly to Mexican customers.
