Correos de México, formally the Servicio Postal Mexicano, is the national postal service of Mexico. It operates the country's public postal network and provides correspondence, messaging and parcel services for individuals, businesses and public institutions. Its role is to connect communities across Mexico while providing accessible postal and delivery services through its network of postal facilities.
The carrier handles traditional letters and postcards as well as parcels and registered postal items. Its published service information also includes individual parcel services, international postal products and additional services for customers who need features such as registered handling or proof of receipt. Business customers can use services designed for larger mailing volumes and specialized parcel requirements.
For faster parcel and document delivery, Correos de México operates Mexpost, its express messaging and parcel service. Domestic Mexpost shipments can be deposited at postal offices that have a Mexpost counter, with different delivery options available according to the route and service selected.
Correos de México also accepts international postal and Mexpost shipments, but its own national operating network is in Mexico. Once an outbound international item leaves the Mexican postal network, transportation and final delivery may involve the postal operator or delivery network serving the destination country.
How to Track Correos de Mexico packages
To Track a Correos de Mexico package with 4Tracking, enter the shipment's tracking or guide number into the tracking field and start the search. 4Tracking can identify supported carriers automatically, or you can select Correos de Mexico manually when necessary. The package tracking results can display available events such as acceptance, transportation between postal facilities, arrival at a delivery office, assignment to a courier and final delivery.
Correos de México also provides its own official shipment Tracking system. The carrier's tracking page asks for the guide number and the applicable year before displaying recorded events. Official tracking records can include the date, time, processing location and status of each registered movement.
If you have just received a tracking number and no result is available yet, the package may not have received its first postal scan. Confirm that you entered the complete guide correctly and allow time for the shipment to be accepted and registered in the postal system.
Correos de Mexico tracking number formats
Tracking numbers can vary according to the postal product. For Mexpost, official Correos de México technical documentation specifies a 13-character guide consisting of a two-letter prefix, eight consecutive digits, one numeric check digit and a two-letter suffix. The documented Mexpost structure begins with a prefix whose first letter is E.
An official format example is EE000000001MX. In this structure, EE is the service prefix, 00000000 is the eight-digit consecutive number, 1 is the check digit and MX is the country suffix. Actual shipment numbers contain their own unique numeric sequence, so this example should only be used to understand the format.
Other registered postal products can use different prefixes even though they may also appear as 13-character postal identifiers. For this reason, do not change the letters or digits to make a number resemble a Mexpost guide. Enter the complete identifier exactly as it appears on the receipt, shipping label or confirmation supplied by the sender.
Correos de Mexico delivery times
Delivery time depends on the service selected and the origin and destination within Mexico. Official Correos de México guidance for domestic Mexpost lists three delivery options: next-day delivery, second-day delivery and a standard service of approximately 3 to 5 days.
For example, a shipment accepted under an eligible next-day Mexpost service is intended for delivery on the following day, while a shipment using the second-day option follows the corresponding two-day service. Standard domestic Mexpost is listed at 3 to 5 days. These are service-time categories published by Correos de México and should not be interpreted as a guarantee that every package sent anywhere in Mexico will arrive within the same period.
Actual delivery can depend on the specific route, postal processing schedule, address accuracy, unsuccessful delivery attempts and other operational conditions. For ordinary postal products and services other than Mexpost, use the estimate associated with the product purchased rather than applying Mexpost delivery times to every Correos de México package.
Why Correos de Mexico Tracking may stop updating
A gap between Tracking events can occur while a parcel is traveling between postal facilities or waiting for its next processing scan. The absence of a new event for a short period does not by itself confirm that the shipment has been lost.
Official Correos de México tracking events may show statuses such as receipt at a post office, transit toward the destination, arrival at another postal facility, assignment to a delivery courier, an unsuccessful delivery visit or delivery. Monitoring these events can help determine whether the package is still moving or has reached the local delivery stage.
If an expected delivery date has passed and there have been no meaningful updates, verify the number through both 4Tracking and the official Correos de México Tracking service. The sender's postal receipt can also be useful because it identifies the service used and provides the guide needed when requesting assistance.
How to contact Correos de Mexico about shipment issues
Correos de México publishes contacto@correosdemexico.gob.mx as its official email address for questions and information. When contacting the carrier about a package, include the complete tracking number, the sender and recipient details when appropriate, the date of mailing and a description of the problem.
The postal service also has a formal shipment-claim procedure. Official guidance states that claims apply to Registered and Mexpost shipments and may be used when a shipment has exceeded its delivery time or has arrived damaged. Claims can be presented at postal offices, and Correos de México also provides an online process for eligible cases.
Keep the original postal receipt and shipment documents until the issue is resolved. These records can be important when Correos de México needs to investigate the route of a registered item, verify the service purchased or process a formal claim.
Frequently asked questions about Correos de Mexico package tracking issues
Why is my Correos de Mexico tracking number not working?
The package may not yet have received its first scan, the guide may have been entered incorrectly or you may be using an order reference instead of the postal tracking number. Copy the complete guide from the postal receipt or shipping confirmation and try Tracking again after the shipment has been accepted.
Can I Track a Correos de Mexico package with 4Tracking?
Yes. Enter your Correos de Mexico tracking number on 4Tracking to follow the available package tracking events. If the carrier is not detected automatically, select Correos de Mexico manually before starting the search.
What does a Mexpost tracking number look like?
Official technical documentation describes a 13-character Mexpost guide containing two letters, eight consecutive digits, one check digit and a two-letter suffix. A documented example is EE000000001MX. Other Correos de México postal products can use different prefixes, so always use the exact guide printed on your shipment documents.
How long does Mexpost delivery take within Mexico?
Correos de México publishes domestic Mexpost service options for next-day delivery, second-day delivery and standard delivery of approximately 3 to 5 days. Availability and actual transit time depend on the service and route used for the shipment.
Why has my Correos de Mexico package stopped moving?
The parcel may be traveling between facilities or waiting for another processing event. Continue checking Tracking for a new scan. If the expected delivery period has passed without progress, contact Correos de México with the guide number and mailing details.
What should I do if nobody was available to receive my package?
