Mexico Address Format: How to Write It Correctly
How to write a Mexican address: street and number order, exterior and interior numbers, the colonia, postal code and state, with a formatted example.
Updated 14 October 2026 · 2 min read
A Mexican address usually goes in this order: recipient, street name and number, colonia, postal code and municipality or city, then state. Unlike many English-speaking countries, the street name comes before the number, and the neighbourhood is a required element.
The line order
- Recipient. Person or company name.
- Street and number. Street type and name, then the exterior number, and an interior number if needed.
- Colonia. Often abbreviated Col.
- Postal code, municipality or city. The five-digit código postal, then the place name.
- State. Written in full or abbreviated.
- Country. Only for international mail.
Street, number and unit
The street type is usually written before the name: Calle, Avenida (Av.), Boulevard (Blvd.), Calzada, Privada, Cerrada. The number follows the name. Exterior number is abbreviated Núm. Ext. or No. Ext., and the interior (apartment, office or house in a courtyard) is Núm. Int. or just Int. Some addresses add the street intersection, using the phrase entre calle A y calle B, to help the courier.
Colonia and other names
The colonia identifies the neighbourhood and is a normal piece of the address. Some places also use the words fraccionamiento (a housing development), unidad habitacional or residencial. Write the name as it appears on official documents, since similar names exist in the same city.
Language
Addresses are in Spanish. Keep accents and the letter ñ where they belong. When an address is part of an international shipment, the country is written on the last line, but the rest stays in Spanish so local carriers can read it.

The values are placeholders, not a real address.
Adding an exact location
Where a street has no number or the entrance is not obvious, add a landmark or reference line, and optionally a UPCS code in the form MX-XXXX-XXXX (a placeholder). The code points to a 3 m by 3 m cell and does not replace the postal code or the colonia. For more, see the Mexico overview, the postal code format and delivery challenges.
Frequently asked questions
What is a colonia in a Mexican address?
A colonia is a neighbourhood. It is a standard part of the address and is usually written after the street line, before the postal code and city.
What does S/N mean?
S/N stands for sin número, meaning without a number. It appears when a property has no street number.
