How to Send a Fax to Mexico
Mexican notaries, government agencies, and the maquiladora manufacturing sector use fax for cross-border trade documentation, customs filings, and legal attestations. SAT (Servicio de Administracion Tributaria, the tax authority) communications often involve fax for correspondence and administrative notices. The maquiladora industry along the US-Mexico border relies on fax for rapid exchange of production orders and shipping documents between US buyers and Mexican manufacturers.
Dialing Instructions
International format: +52 followed by the 10-digit number (area code + local number, no trunk prefix needed from abroad). Mexico City area code is 55 (dial +52-55-XXXX-XXXX), Guadalajara is 33 (+52-33-XXXX-XXXX), and Monterrey is 81 (+52-81-XXXX-XXXX).
Delivery & Timing
Typically 1-2 minutes per page when sending to Mexico from North America. Transmission to Mexico City and Guadalajara is generally excellent given Mexico's modern telecommunications infrastructure.
Legal & Regulatory Information
Mexico's Ley de Firma Electronica Avanzada (Advanced Electronic Signature Law) establishes the legal framework for electronic communications with Mexican government entities, defining what constitutes a valid electronic signature for public sector transactions. Faxed documents with handwritten signatures remain valid for private sector contracts and many government filings.

Faxing to Mexico — FAQ
SAT primarily uses its digital portal (SAT ID and the Buzon Tributario) for official communications, but regional SAT offices still maintain fax lines for certain administrative correspondence, taxpayer inquiries, and follow-up on pending matters. Always confirm with the specific SAT office before faxing.
For border cities: Tijuana uses area code 664 (+52-664-XXX-XXXX), Juarez uses 656 (+52-656-XXX-XXXX), and Monterrey uses 81 (+52-81-XXXX-XXXX). Send FAX Mail supports faxing to all Mexican area codes at $12.99/month, well below eFax's $18.99/month rate.

Mexican fax numbers are always landlines. Fax machines connect over PSTN lines. All Mexican landline and mobile numbers are 10 digits (2-3 digit area code + 7-8 digit local number). From outside Mexico, always dial +52 followed by the full 10-digit number with no additional prefixes.
