Post Codes and the Postal System in Mexico

Information on sending and receiving letters and parcels, mail services, finding a Mexico postal/ZIP code and how to write addresses in Mexico...

A postal code or ZIP code in Mexico is called a código postal (C.P.). Mexican postal codes are made up of five digits. The first two digits identify the state, for example post codes beginning with 0 or 1 correspond to Mexico City. All other post codes are assigned in alphabetical order.

Writing Mexican Addresses

Mexican addresses are written as follows:

  • Name
    Street name and number
    Name of borough/district (colonia) or village
    County/municipality (municipio or delegación)
    Postal code (C.P.)
    City and state

For example:

  • Sr. Alvarez
    Calle Tamarindos 24
    Col. Polanco 
    Del. Miguel Hidalgo
    C.P. 11234
    México CDMX

Mexican Street Addresses

It should be noted that route finding in certain cities is not always easy as many addresses in a street are without a number (sin número). It is common in Mexico City to not only provide the street name and number (if it exists), but also to state between which perpendicular streets the address is located. This applies to taxis, store delivery services, and often needs to be put on official documents.

Mail and Postal Services

Post offices (correos) can be found throughout the towns and cities of Mexico and postal services are provided by Mexico's national postal service, Correos de México (in Spanish). The service can be unreliable and slow and to ensure that a package or important mail arrives in a timely manner, it may be worth using its MexPost service, although this may be more expensive.

Post Offices

Post offices are generally open Monday to Friday from 09:00 to mid-afternoon and on Saturday mornings. In large towns and cities they may remain open until 18:00 on a weekday. However, opening hours vary depending on the location.

  • Find a local post office - select the state (estado), county/municipality (municipio or delegación) and borough/district (colonia)

When sending parcels from a post office, items should not be sealed so that staff can check the contents as some items may not be sent though the post. If sending items abroad it may be necessary to fill out customs forms. All letters and packages are weighed to calculate the correct postal rate.

Information about prohibited items for import and export can be found in the Aduanas section of the Servicio de Administración Tributaria (SAT) website (in Spanish).
