How to send a fax to Mexico

Why fax to Mexico?

If your recipient in Mexico asks for a fax, you can send signed forms, supporting documents or other paperwork from your phone or computer. Confirm that the recipient accepts your document by fax and check their current fax number before sending.

What you need

To send a fax to Mexico with unofax you need four things:

• Your document: PDF, Word, image, or any supported file. PDF gives the best results.
• The recipient's fax number: Mexico uses +52 followed by a ten-digit number. Mexico City (55), Guadalajara (33) and Monterrey (81) have two-digit area codes followed by eight digits; other cities have three-digit area codes followed by seven. Leave out the old 01, 044 and 045 prefixes.
• A payment method: credit card, debit card, Apple Pay, or Google Pay.
• Your email address: for delivery confirmation and proof of receipt.

No account, no subscription, no fax machine required.

Tips for faxing to Mexico

A few things to keep in mind when faxing to Mexico:

• Local time: Most of Mexico uses Central Standard Time (UTC−6) all year and no longer observes daylight saving time. Quintana Roo, Baja California and some northern border cities keep their own time, so check the recipient's city. Send during the recipient's business hours when possible.
• Supported numbers: Use the recipient's active landline fax number. Premium-rate numbers are blocked.
• Cover sheet: include the recipient, department, reference number and your contact details.
• Use PDF for best quality: official forms, scans, and signed documents fax more clearly when converted to a clean PDF before upload.
• Check acceptance: confirm the submission deadline and any required follow-up. Delivery confirmation means the receiving fax system acknowledged receipt, not that a person has reviewed or accepted the document.
