An intercom is a security checkpoint with terrible audio. It wants three pieces of information, in a fixed order, and it wants them before it wants anything else.
Get the order right and the gate opens. Get it wrong and you get questions, which through a crackling speaker in your second language is exactly the situation you were hoping to avoid.
Who, where, why - in that order
-
Buenas, soy Andrey, vengo a ver a Ana del 302.Hi, I'm Andrey, here to see Ana in 302.
That single sentence contains all three: your name, the unit, the purpose. Nothing else is needed and nothing else helps.
The instinct most people have is to lead with the purpose - I’m here to see someone - which is the least useful of the three, because it prompts an immediate follow-up. Leading with your own name does something small and social: it makes you a person rather than a voice.
- quién Buenas, soy Andrey Hi, I'm Andrey Buenas alone is a full greeting at any hour. No need for buenos días.
- dónde Del 302 / vengo al 302 From 302 / I'm coming to 302 The number is the single most useful word in the sentence.
- por qué Vengo a ver a Ana I'm here to see Ana A name, not a relationship. Nobody needs to know how you know them.
- si hace falta ¿Le puede marcar, por favor? Could you call up, please? Offering the call ends almost every standoff.

The question that stumps everybody
¿De parte de quién?
It means who shall I say is calling. The answer is your own name.
Roughly half of foreign residents answer with the name of the person they came to see, because the sentence sounds like it is asking who you are looking for. It is not. De parte de means on behalf of or from - it is asking for the sender, and you are the sender.
-
De parte de Andrey.It's Andrey.
-
De parte de Andrey, del 302.It's Andrey, from 302.
Its companion question is ¿lo esperan? or ¿la esperan? - are they expecting you. Answer honestly and offer the fix in the same breath:
-
Sí, ya sabe que vengo.Yes, they know I'm coming.
-
No, pero ¿le puede marcar, por favor?No, but could you call up, please?
¿De parte de quién? → your name.
¿Lo esperan? → sí / no, pero ¿le puede marcar?
Abajo does not mean downstairs
Estoy abajo is used at buildings with no stairs, houses with one floor, and gates on flat streets. It is not really describing vertical position - it means at street level, outside, at the entrance.
That is why it works everywhere and why it is the single most-sent arrival message in the country.
| Se dice | Cuándo |
|---|---|
| Estoy abajo | You’ve arrived. Works anywhere |
| Ya llegué | Same, slightly less specific about where |
| Estoy en el portón | At the big street gate specifically |
| Estoy afuera | Outside, for a house or a bar |
| Ya estoy aquí, tómate tu tiempo | Arrived, no rush - the kind version |
| Toqué el timbre | I rang the bell, in case it doesn’t work |
That last one matters more than it should. Intercoms in Mexico City fail constantly, so toqué el timbre pero creo que no sirve is a completely routine message.

Who you are actually talking to
Four different roles, four different registers. Using the right word signals that you live here.
| La persona | Qué hace |
|---|---|
| Portero / portera | Looks after the building day to day, minds the entrance |
| Conserje | Much the same, slightly more formal word |
| Vigilante | Security specifically, often a contracted service |
| Administrador | The building’s manager - a legal role, rarely at the door |
| Vecino | A neighbor who happened to answer the intercom |
The portero is the one you will deal with most, and the role has more texture to it than the word suggests - it is part caretaker, part gatekeeper, part institutional memory of the building.1 The administrador is worth understanding properly, because it is not a job title someone invented. Under Mexico City’s condominium law, buildings run under a registered régimen with an administrador and an internal set of rules, and PROSOC - the city’s Procuraduría Social - is the authority that registers those rules, handles condominium complaints and runs the arbitration.23
Which brings us to a right almost no foreign resident knows they have.
The Mexico City condominium law requires a discrimination-free environment and prohibits imposing discriminatory conditions on visitors, guests or employees - on grounds including ethnic or national origin, appearance, skin color, language, gender, age, disability, social condition, religion, migratory status and sexual orientation.
Complaints about how a building is run go to PROSOC, not to the guard.
In practice you will rarely need it, and it is not a sentence to deploy at a gate at eleven at night. But it is worth knowing that the internal rules are a registered document with an authority behind them, rather than whatever the person at the door decides today.4
Deliveries rewrote the gate
The most-spoken sentence at CDMX gates now is not a visitor’s. It is a courier’s.
Funciona
- Traigo un pedido para el 302. - unit first, always
- ¿Lo dejo en recepción? - usually yes, and faster for everyone
- ¿Me firma de recibido? - what you'll be asked downstairs
- Me lo dejaron en la caseta. - where your parcel actually is
Genera preguntas
- Vengo a entregar algo. - to whom?
- Es para una persona del edificio. - which one?
- Ahorita subo. - many buildings will not allow it
- Reading out the full address you already typed into the app
If a parcel has gone missing, ¿no me dejaron un paquete en la caseta? solves it about eighty percent of the time. The guard post is where things live.
- ¿De parte de quién?Who shall I say is calling?
- De parte de Andrey, vengo a ver a Ana del 302It's Andrey, here to see Ana in 302
- ¿Lo espera?Is she expecting you?
- Sí, ya sabe que vengo. Si quiere, márqueleYes, she knows. Call up if you like
Offering the phone call is the move. It hands the decision to the resident, which is what the guard wanted anyway.

The short version
Estoy abajo, ¿me abres? for friends. For everyone else, three things in one breath:
-
Buenas, soy Andrey, vengo a ver a Ana del 302. ¿Le puede marcar, por favor?Hi, I'm Andrey, here to see Ana in 302. Could you call up, please?
Name, unit, purpose, and an offer to let someone else confirm it. That sentence has never failed at a gate, which is more than can be said for most intercoms.
