Meaning
CDMX is the widely used abbreviation for Ciudad de México, the official name of Mexico City, and it appears throughout local government, transport, tourism, addresses, media and everyday urban shorthand.
How it is used
Mexico City's official tourism and government sites use CDMX throughout public-facing material, including transport maps, attraction listings, itineraries and addresses. The abbreviation is therefore both institutional and conversational, especially in writing, signage, social media and travel planning.
Examples
- “Llegamos a la CDMX por la tarde.”
- “Consulta el mapa de transporte de la CDMX antes de salir.”
Pronunciation
/se ðe eme ˈekis/ · seh-deh-eh-meh-EH-kees
Tone and register
Neutral and practical. It is especially common in written communication and branding, while speakers may simply say Ciudad de México, México or la ciudad depending on context.
Visitor guidance
Do not confuse CDMX with the Estado de México, which is a separate federal entity surrounding much of the capital. When a form or address requires the legal place name, use Ciudad de México unless the form specifically asks for an abbreviation.
Cultural context
CDMX became a compact visual identity for the capital and now appears across mobility, tourism, cultural programming, government websites and everyday digital communication. Its usefulness comes from distinguishing the capital clearly in contexts where México could mean either the country or the city.
