ID and age: what they ask at the door and what will not work

The age is 18 — and the number is not written in the law

Se prohíbe el acceso o permanencia a las áreas de juegos con apuestas de los establecimientos, a las personas que: I. Sean menores de edad, excepto cuando en compañía de un adulto ingresen a espectáculos en vivo. En ningún caso los menores de edad podrán participar en el cruce de apuestas.

Regulation of the Federal Gaming and Raffles Act, article 5, section I

Notice what is missing: there is no figure in that text. The rule says «minors» and leaves the civil code to define one. So the accurate sentence is not «Mexican law sets the age at 18» but «the law bars minors, and in Mexico majority arrives at 18» — same door policy, and the version you can defend if someone argues.

The operators do print it. Codere heads its venue-site footer with «SÓLO PARA MAYORES DE 18 AÑOS» in capitals, and clause 1.2 of Palace's terms says betting in Mexico is «únicamente para MAYORES DE 18 AÑOS», citing the regulation, its permit and the house rulebook approved by the Interior Ministry.

Where the «21» in your search results comes from

In November 2014 the Chamber of Deputies and the Interior Ministry announced an agreement to overhaul the 1947 gaming act, and one of its points was raising the entry age to 21. The overhaul never passed. The legislative-history page for that law carries a single line under amendments — «sin reforma» — beneath a text published on 31 December 1947. Seventy-eight years, not one decree.

Twelve years on it still circulates, rewritten in the present tense by pages that never checked whether it became law. The English results are thin enough to explain why:

Drinking age is 18 as well, so there is no gap to plan around

This catches American visitors, because at home the two ages differ. In Mexico they do not: the Quintana Roo alcohol law, current text December 2025, forbids selling to anyone under 18 — the same line as the betting floor, so one document opens both doors. Article 5 adds a rule that matters in a city where the evening starts at a nightclub: remaining in a betting area while drunk is prohibited, and enforcing that is the venue's legal duty.

What they ask for at the door

The law names no document at all. It puts the duty on the room: article 29, section V Bis, in force since October 2013, requires the permit holder to «verify that the people entering the betting areas» do not fall under article 5. How it verifies is left to its own rulebook, which is why the answer changes from door to door.

Of the fourteen licensed rooms in the state, Palace Bingo is the only one that publishes its requirements. Word for word, from its Cancun page:

Indispensable mostrar original de identificación oficial vigente con firma y fotografía expedida por autoridad Federal, Estatal, Municipal y tarjeta de juego del cliente; para el caso de extranjeros pasaporte expedido en su país de origen.

Palace Bingo & Sport Bets Casino Cancún, published on its own site

Elsewhere there are only traces. A July 2024 review of Casino Macao shouts it in capitals — bring documents, they will demand them — because the room opens a client file and issues a card before you play. At Jubilee entry is free and the age is 18, but nothing is published about ID.

Three things we cannot confirm, and say so

• A US or Canadian driver's licence. Palace names one option for a foreigner, the passport, which reads as excluding a licence. That is our reading of a text, not observed practice.
• The FMM tourist form. An immigration document, not a photo-and-signature ID. No room publishes that it accepts one.
• A photocopy, or the forum rule «licence to get in, passport to get paid». The published wording demands an original; the forum rule is plausible but undocumented. Carry the passport.

The second check is at the cage, not at the door

Betting games are a «vulnerable activity» under Mexico's anti-money-laundering act, and that produces three thresholds the room does not choose. They are written in UMA, an official daily unit worth 117.31 pesos for 2026, so all three figures move every February.

The first threshold is about 38,000 pesos — a good night, not a jackpot — and it is the practical reason a visitor needs a passport: the cage cannot pay you without identifying you, and you have no Mexican voter card. Splitting the payout does not help: the law covers transactions «apparently linked to each other». What is withheld, and which receipts you are owed, is on tax on winnings.

Who else gets turned away, and the one exception for children

• Anyone drunk or on prohibited substances, anyone armed, and police or military personnel in uniform and on duty — a distinction the rule makes explicitly.
• Anyone disturbing order, and anyone caught cheating, at any time in the past.
• Anyone who does not comply with the venue's internal rulebook, approved in advance by the Interior Ministry. That clause underpins every house rule, including what you wear.

Section I also opens one narrow door: a minor may enter «accompanied by an adult» for live shows, and may under no circumstances bet. That is why Casino By Yak, on the second floor of Plaza Las Américas, also bills itself as an entertainment venue. Article 29 closes the circle: a prize is never handed to a minor, only to a parent or guardian on proof of the relationship.

Online: same age, different moment

On a licensed Mexican site the age is the same, but the paperwork arrives in the opposite order: nothing at registration, everything before the first withdrawal. What that means for a visitor with no Mexican bank account is on the online page; the money side of the same trip is on dollars or pesos.
