How the Mexican Postal Service Works: A Practical Guide for Travelers and Expats

If you’re traveling, living, or spending part of the year in Mexico, you may eventually need to send or receive mail. The Mexican postal service—Correos de México—works a bit differently than what many Canadians and Americans are used to. Understanding how it operates can save you time, frustration, and lost packages.

This guide explains how the Mexican postal system works, what services are available, and when you may want to use alternatives.


What Is Correos de México?

Correos de México is Mexico’s national postal service. It has been operating in various forms since the 1500s and today maintains thousands of post offices across the country, from large cities to small towns.

While it provides many of the same services as Canada Post or USPS, expectations should be adjusted. Delivery times are generally longer, and some services are better suited for documents than packages.


Addressing Mail in Mexico

One of the biggest differences is how addresses work.

A typical Mexican address looks like this:

Name
Street Name and Number
Colonia (Neighborhood)
City, State
Postal Code (Código Postal)
Mexico

Key Address Components

  • Colonia is critical and functions like a neighborhood or district.
  • Postal codes are very specific and often cover only a few blocks.
  • Rural areas may not have home delivery at all.

If you’re mailing something to Mexico, always verify the correct colonia and postal code.


Home Delivery vs. Post Office Pickup

Unlike in Canada or the U.S., home mail delivery is not guaranteed everywhere.

  • In large cities: limited home delivery may exist
  • In small towns and rural areas: mail is often held at the post office
  • Many residents use “Lista de Correos” (General Delivery)

Lista de Correos (General Delivery)

Mail is addressed to the recipient care of the local post office. The recipient must:

  • Visit the post office in person
  • Present valid photo ID
  • Ask if mail has arrived under their name

This is common practice for travelers and seasonal residents.


Services Offered by Correos de México

Regular Mail

  • Letters and postcards
  • Very affordable
  • Slow but usually reliable for non-urgent items

Registered Mail (Correo Certificado)

  • Tracking within Mexico
  • Signature required
  • Recommended for important documents

Parcel Service

  • Available, but slow
  • Limited tracking
  • Not ideal for high-value items

International Mail

  • Can take several weeks (or longer)
  • Customs delays are common
  • Tracking may stop once the item enters Mexico

How Long Does Mail Take?

Delivery times vary widely.

Type of MailTypical Time
Local letters5–10 business days
Domestic mail1–3 weeks
International mail3–6+ weeks
Parcels4–8+ weeks

Holidays, customs inspections, and regional staffing all affect timing.


Tracking Mail in Mexico

Tracking exists but is limited.

  • Registered mail can be tracked online
  • Updates may be infrequent
  • International tracking often ends once the package clears customs

For important or time-sensitive shipments, Correos tracking can be unreliable.


Customs and Import Considerations

International mail entering Mexico goes through customs.

  • Packages may be opened for inspection
  • Duties and taxes may apply
  • Some items are restricted or prohibited
  • Clearance delays are common

If duties are owed, the recipient must usually pay them before release.


When to Use Private Courier Services

Many travelers and expats prefer private carriers such as:

  • DHL
  • FedEx
  • UPS
  • Estafeta

Advantages

  • Faster delivery
  • Reliable tracking
  • Door-to-door service
  • Better customer support

Disadvantages

  • Higher cost
  • Duties are almost always assessed

For important documents, electronics, or time-sensitive items, private couriers are usually the better choice.


Tips for Travelers, RVers, and Expats

  • Use digital billing and paperless statements whenever possible
  • Have important mail sent to a trusted contact in your home country
  • Use Lista de Correos if staying long-term in one area
  • Avoid sending valuables through standard mail
  • Be patient—mail in Mexico runs on a different timeline

Is the Mexican Postal Service Reliable?

Correos de México works best when:

  • You’re not in a hurry
  • You’re sending documents or letters
  • You understand local pickup procedures

For everyday correspondence, it’s functional and inexpensive. For anything urgent or valuable, alternatives are recommended.


Back in December my son asked if we hade an address here in the Baja that he could send a Christmas Greeting, bellow is a question I posed to my AI app to see if receiving a Christmas greeting was a possibility.


What would my postal code be here at our site Latitude 31.115778 Longitude -114.914499 and where would the closest post office be?

Here’s what I can tell you about the location you’re staying at latitude 31.115778, longitude –114.914499:

📍 Likely Postal Code

Your coordinates place you in northern Mexico, just across the border from Yuma, Arizona — likely in or near San Luis Río Colorado, Sonora. In that region of Baja California / Sonora, postal codes typically fall within the 83000–85994 range for Baja California and 83000–85994 for Sonora per the Mexican postal code system (the ranges vary by state) .

  • The official Correos de México postal code for the main San Luis Río Colorado postal area is likely around 83401 — this is the postal code used at the prominent local post office in town.

However, because rural addresses can be outside the official town’s coded area, your exact site might be assigned a slightly different 5-digit code depending on local colonia / settlement name. The best way to confirm is to check with the local post office (they can lookup the exact area for you).

📮 Closest Post Office

The nearest established Mexican postal service location is likely:

Correos de México / San Luis Río Colorado, Son.

  • 📍 Address: José María Morelos y Pavón, Cuauhtémoc, 83401 San Luis Río Colorado, Sonora, Mexico
  • 🕐 Typical Hours: Weekdays 08:00–16:30; Saturday 09:00–13:00 (may vary slightly)

This is the main Correos de México post office in San Luis Río Colorado, and it’s where most mail and parcels are processed for the region.


📬 Tips for Using This Postal Code and Office

  • When addressing mail to your site, use: [Your name] [Street address / lot description] San Luis Río Colorado, Son. C.P. 83401 MÉXICO (If you have a specific street/colonia name, include it before the city.)
  • If mail carriers don’t deliver right to your site, you can have parcels held “en Lista de Correos” (general delivery) at the post office — then pick them up with your ID.
  • For parcels from abroad, include your Mexican phone number and postal code 83401 to help with customs and delivery.

Final Thoughts

The Mexican postal service reflects Mexico itself—historic, widespread, and a bit slower paced. With the right expectations and a little planning, it can serve your needs just fine.

If you’re traveling through Mexico or living life on the road like we are, understanding how mail works is just one more step toward smoother adventures.

2025 in Review: Miles, Memories, and Finding Our Rhythm

By The Buchanan’s Rolling Down The Road
December 2025

Every year seems to move faster than the last, but 2025 felt like it moved at highway speed. From desert mornings at Boyce Thompson Arboretum to lake days in Ontario, new states on the map, mechanical challenges, and finally settling into winter life on a quiet Mexican beach — this year reminded us why we chose this life.


Winter & Spring in the Arizona Desert

We started the year camped and volunteering once again at Boyce Thompson Arboretum. The desert welcomed us back with cactus blossoms, hummingbirds at the feeders, and the ever-present coati wandering through the grounds. Miss Laurie spent plenty of time rock hounding, while we both enjoyed the familiar rhythm of volunteer life.

January through March were filled with great company and simple adventures:

  • Kayaking the Lower Salt River with Ray & Karen, watching wild horses along the banks
  • Off-roading Box Canyon with Al & Carmen, followed by unforgettable Mexican food
  • Visits with friends in Show Low, Tucson, and Gilbert

Of course, no season is complete without a mechanical lesson. A leaking freshwater tank on Thunder turned into a full replacement, along with a new SeeLevel tank monitoring system.


Saying Goodbye & Heading East

April marked our final month at the Arboretum. A volunteer thank-you dinner, final walks among blooming cactus, and a special highlight — watching my grandson Andrew play baseball during a Phoenix tournament — made the goodbye meaningful and bittersweet.

On April 28, we turned Thunder east and began our spring migration back to Ontario.

The journey was a familiar patchwork of:

  • Walmart and Cracker Barrel overnights
  • Welcome centers and Harvest Hosts
  • Visits with friends and family along the way

We crossed back into Canada on May 8, settling into short stays until our summer site became available.


Summer at Sunni Bank RV Park

By mid-May, we arrived at Sunni Bank RV Park in Ontario, where summer truly began. Reconnecting with longtime friends Bob & Irena turned into a season full of laughter, food, and friendly competition.

Highlights included:

  • Kayaking the Grand River
  • Cornhole and washer board tournaments
  • Campfires and sunset conversations
  • An ongoing (very serious) search for the best Lake Erie perch

Spring rains left Thunder sunk deep enough to break patio stones, and our open site — great for solar and Starlink — came with the challenge of nearby roosters. Still, once settled, it felt like home.


Summer Curveballs & Small Victories

Summer also brought its share of challenges:

  • A leaking washer/dryer valve
  • A burned-out solar charge controller
  • Leveling system switch failures
  • Weak chassis batteries

Thanks to persistence, ingenuity, and Bob “knowing a guy,” everything was repaired. We also restored our Clam screen porch — a favorite spot for afternoon naps — and fully embraced cornhole as our new obsession.

Birthdays were celebrated, briskets were smoked, and long, slow summer days reminded us how important community is on the road.


Fall Travels & New States

October arrived quickly, and with it, packing up and climbing Thunder out of the spring ruts — literally. From there, we headed west on a new northern route, adding four new states to our travel map:

Nebraska • Wyoming • Colorado • Utah

Highlights included:

  • A charming $10/night city campground in Beaver Crossing, Nebraska
  • Climbing I-70 through the Rocky Mountains (with a bag of chips exploding from elevation)
  • Six nights boondocking near Goblin Valley State Park
  • Exploring Lake Powell and quiet desert mesas

Each mile reminded us why we still love long travel days.


Vegas, the Border & an Unexpected Breakdown

We paused in Las Vegas, splitting time between our time-share and keeping Thunder comfortable at the Elks Lodge — a perfect solution for us and Mister Sam.

Mid-November, we headed south toward Mexico. The border crossing at Mexicali was smooth… until one mile later, when a torque rod failed. With no good options, we strapped it up and carefully drove 185 kilometers south to San Felipe.

Sometimes the only option is forward.


Wintering in Mexico

We’re now settled at El Dorado Ranch Resort in San Felipe, Mexico, where life has slowed to a gentler pace.

Our days include:

  • Quiet mornings on an empty sand beach
  • Pool time, hot tubs, and water volleyball
  • Pickleball lessons for Miss Laurie
  • Cornhole games and fresh shrimp on the grill

While we’re still finding our social rhythm here, everyone has been welcoming and kind. Christmas was spent mostly on the beach — different, but just right for this season of life.


Looking Back at 2025

As the year comes to a close, we’re reminded that this lifestyle isn’t about perfect plans. It’s about adaptability, community, and finding joy in the in-between moments — even when something breaks, a route changes, or time moves faster than expected.

2025 gave us new states, old friends, challenges overcome, and a deeper appreciation for the road ahead.

And somehow, it still feels like we’re just getting started.
