The addresses we hold

This page shows every mailing address we hold for Sonyone, starting with the one a cancellation letter should go to in Ciudad de México, 01210, and how to address the envelope so it arrives without a query.

Where the letter goesMailing address

SonyoneProlongación Paseo de la Reforma 60001210 Ciudad de MéxicoMexico

The Mexico address on file for Sonyone. Postal code 01210.

How to address the envelope

  1. Copy it exactly onto the envelope

    Address the envelope to Prolongación Paseo de la Reforma 600, 01210 Ciudad de México, Mexico. Everything on those lines matters for the sorting machines, so nothing is abbreviated by hand.

  2. Add your return address

    Print your return address in the top-left corner. Without it, an undeliverable letter is simply lost instead of returned to you.

  3. Send it certified

    Ask at the counter for the certified service with a return receipt: the fee is on top of the postage, the receipt is postmarked, and the article number traces the delivery.

  4. Keep the proof together

    Your copy of the letter, the mailing receipt and the tracking record belong together in one file.
