If you’ve ever tried to mail a postcard from the heart of the Zócalo or just tried to fill out a dropdown menu on a travel site, you’ve probably hit a wall. You’re looking for the "state" to put down for your location. You see "Mexico" as an option, but you also see "Mexico City." It’s confusing.
Honestly, the question of what state is mexico city mexico in is one of those things that sounds like it should have a one-word answer. But, like most things in this massive, beautiful, slightly chaotic metropolis, it’s a bit more complicated than that.
Let's get the short answer out of the way: Mexico City is not in a state. Wait, what?
Yeah, it's true. It is its own thing entirely. While Mexico has 31 states, Mexico City is the 32nd "federative entity." Think of it like Washington D.C. in the United States, but with way more tacos and a population that would make D.C. look like a sleepy village.
The Big Name Change: From DF to CDMX
For decades, if you asked anyone where they lived in the capital, they’d say "el DF" (pronounced el day-effay). This stood for Distrito Federal, or the Federal District. It was a territory managed directly by the federal government.
But in 2016, everything changed.
The government decided to give the city more autonomy. They basically said, "You’re grown up enough to make your own rules now." They officially ditched the "Federal District" title and rebranded as Ciudad de México, or CDMX.
- Old Name: Distrito Federal (DF)
- New Name: Ciudad de México (CDMX)
- The Vibe: Independent, but still the capital.
Even though it’s been years since the change, you’ll still hear locals calling themselves "chilangos" or saying they’re from "el DF." Habits die hard in a city this old.

The "State of Mexico" Confusion
Now, here is where it gets really trippy. There is a state actually called Mexico (Estado de México).
People often call it "Edoméx" for short. This state is huge, and it actually wraps around Mexico City on three sides like a giant horseshoe. Because the city has grown so much, the "Greater Mexico City" area actually spills over into the State of Mexico.
So, you could be standing on one side of a street in Mexico City (the entity) and walk across the street into the State of Mexico (the state).
How to tell the difference:
- Mexico City (CDMX): The actual capital. It has 16 boroughs called alcaldías (like Coyoacán or Cuauhtémoc).
- State of Mexico (Edoméx): The surrounding state. Its capital is Toluca, not Mexico City.
If you’re visiting as a tourist and staying in Reforma, Polanco, or Roma Norte, you are 100% in Mexico City, not in a state.
Why Does This Even Matter?
You might wonder why anyone cares about the legal status of a city. Well, for the people living there, it was a huge deal. Before the 2016 reforms, the city didn't have its own constitution. It didn't have the same level of control over its own police force or budget that a state would.

Now, CDMX has its own local congress and its own constitution. It’s basically a state in everything but name. The only reason it isn't officially called a "state" is because of a specific clause in the Mexican Constitution that says as long as it’s the seat of the federal government, it has to remain a federal entity.
Basically, it's the house where the President lives, so the President wants to keep a close eye on it.
Quick Facts for Your Next Trip
If you're planning a visit or just curious, here's the "too long; didn't read" version of the geography:
- Official Name: Ciudad de México (CDMX).
- Location: Nestled in the Valley of Mexico, high up at about 7,350 feet (2,240 meters).
- State Status: None. It is a "Federal Entity."
- Bordering States: Mostly the State of Mexico and a little bit of Morelos to the south.
Honestly, the locals don't spend much time worrying about whether they live in a "state" or an "entity." They're too busy navigating the traffic or finding the best al pastor in their neighborhood.
What to Do Next
If you're filling out a form and it asks for the "state" while you're in Mexico City, just look for CDMX, Ciudad de México, or sometimes Distrito Federal (if the website hasn't been updated since 2015).
If you are actually planning a trip, don't let the administrative jargon scare you off. Just remember that the city is massive. If you're looking at hotels, make sure they are actually in Mexico City and not way out in the State of Mexico suburbs like Naucalpan or Ecatepec, unless you're prepared for a very long commute.

Pro Tip: Download a map that clearly shows the 16 alcaldías. If your destination is within one of those, you're in the heart of the action.
Actionable Steps:
- Update your address book: If you have friends in the capital, start using "CDMX" instead of "DF."
- Check your transit: If you're taking a bus from the city to the pyramids of Teotihuacán, you’ll be crossing from Mexico City into the State of Mexico. Keep your ID handy!
- Verify your hotel location: Use a map to ensure your "Mexico City" stay isn't actually a two-hour drive away in the surrounding state.
