MexicoChecked 18 August 2026

Depends on your industryWork: MediumEnforcement: Waking up

In one paragraph: Mexico's general privacy law does not care where you store data. There is no approved-country list, no standard contract to sign and no permission to ask for. You need the right wording in your privacy notice and, usually, the person's consent. The rules that actually pin data to Mexico live in banking, money-laundering and tax law, not in the privacy law.
The catch: The relaxed headline stops the moment you are a bank, a stockbroker, a crowdfunding platform, an insurer or a phone company. Banks need written permission from the banking regulator before any processing happens abroad. Separately, anti-money-laundering law and tax law require many ordinary businesses to keep their records at a Mexican address for ten and five years. Those rules bind companies that have never read a privacy law.
Does this apply to me?: Probably yes, but Mexico is unusually vague about it. The privacy law says only that it applies across Mexican territory. It does not spell out when it reaches a company based abroad. The old rulebook did say the law caught a foreign company that used equipment or systems located in Mexico, and let that company appoint a local representative instead of opening an office. That old rulebook belonged to a law that was scrapped in March 2025, so its status today is genuinely unclear. There is no revenue or headcount threshold to fall below.Medium confidence
Can the data leave the country?: Under the general privacy law, yes, and with very little paperwork. Mexico has no list of approved countries and no list of banned ones. Sending data to a company abroad is treated exactly like sending it to a company down the road: say so in your privacy notice, get the person's consent unless one of seven exceptions applies, and pass the privacy notice on to whoever receives the data. Handing data to your own supplier who only follows your instructions is not even counted as a transfer. Five sectors override this, and in three of them the override is severe.High confidence
What do I have to do to send it abroad?: Nothing needs approval and no list exists in either direction. The model is simply unrestricted: any destination is allowed. What you need is a privacy notice that names the transfer and carries a clause where the person accepts or refuses it, plus that person's consent unless one of seven legal exceptions covers you. Because there is no list to populate, the government cannot make this stricter by adding a country. It would take a new law or a new regulation.High confidence
Who enforces this — and are they actually working?: Mexico abolished its independent privacy regulator. The National Institute for Transparency, Access to Information and Data Protection was wound up in March 2025 and its staff, files and cases were moved into a government ministry, the Anti-Corruption and Good Government Ministry. So the referee is now part of the government rather than independent of it. The ministry is staffed, but the law says the detailed procedure for complaints, inspections and fines will be set out in a regulation, and that regulation still has not been published. Financial regulators, by contrast, are visibly active and update their rulebooks almost monthly.Medium confidence
How long must I keep it, and when must I delete it?: There is no single retention period. The privacy law says delete data once it is no longer needed, after a blocking period equal to the time limit for suing over the relationship. One hard ceiling is written into the law: information about someone breaking a contract must be erased six years after the default. The floors are longer and come from other laws. Tax records must be kept five years and their supporting documents must be available at your Mexican tax address. Anti-money-laundering records must be kept ten years at an address you register with the Finance Ministry. Phone companies keep call and location records for two years. Where a floor and a ceiling clash, the floor wins, because the privacy law lets you keep data to meet a legal duty.High confidence
What happens when something goes wrong?: There are at least three clocks and they do not agree. Under the general privacy law you must tell the affected people immediately if a breach significantly harms their money or their reputation, and there is no duty to tell the regulator at all. Banks face a much tighter set: tell the banking regulator immediately, tell affected customers within forty-eight hours, file a full report within five working days, and send a remediation plan within fifteen working days of the incident ending. Phone companies must hand requested records to the authorities within twenty-four hours and keep a team available every hour of every day. Mexico has no general cyber-incident reporting law that catches everyone.High confidence
What's the trap?: Five things catch people out. Every private business in Mexico is now legally required to ask customers for their national population ID number. Anti-money-laundering rules force many ordinary businesses to keep ten years of records at a Mexican address, which quietly rules out a pure foreign cloud setup. Mishandling data can put a person in prison, not just cost a company money. Banks must get written permission before any processing happens abroad, and that includes routine cloud hosting. And the rulebook the privacy law keeps pointing at does not exist.High confidence
What's about to change?: The biggest thing coming is a regulation that is already overdue. The privacy law repeatedly says a rulebook will set the deadlines for complaints, inspections and fines, and the government missed its own June 2025 deadline to publish it. When it lands it could change how enforcement works overnight, with no consultation. Health law was changed in January 2026 to put telehealth on a statutory footing, and the biometric national ID is still being rolled out. The dangerous powers are the ones the government already holds rather than any bill in parliament.Medium confidence

ArgentinaChecked 18 August 2026

Yes, with paperworkWork: MediumEnforcement: Active

In one paragraph: Argentina lets personal data leave the country, but only on paper terms it sets. You either send it to a country the regulator has approved, or you sign the regulator's own model contract with the receiver. No industry has to keep data inside Argentina. Fines are tiny in dollars, but the regulator can order a database shut down, and some misuse is a crime.
The catch: There is no data-residency wall in Argentina, but four sector rules still catch people out. Banks and payment firms must run their technology and security management from inside Argentina, must tell the banking supervisor before they outsource, and must report a cyber incident within one hour. Government bodies must have a working backup data centre by late 2026. And nobody may publish a map showing Argentine territory without the national mapping agency's prior approval.
Does this apply to me?: The main privacy law is Ley 25.326, passed in 2000. It covers personal data held in any file or database in Argentina, public or private. There is no size threshold, no revenue threshold, and no duty to appoint a local representative. The law does not clearly say it reaches a foreign company with no presence in Argentina, and in practice the regulator has acted against local subsidiaries of global firms rather than against foreign entities directly.High confidence
Can the data leave the country?: Yes, with paperwork. The rule is that personal data may not go to a country that does not protect it well enough. The regulator publishes a list of countries it accepts, and for everywhere else you sign its model contract with the receiver. We looked for industries that must keep data inside Argentina - banking, payments, insurance, securities, health, telecoms, government cloud and mapping - and found none as of 18 August 2026.High confidence
What do I have to do to send it abroad?: The model is an approved-destinations list, and it is populated today with about a dozen places, including the whole European Union. If your destination is not on it, use the regulator's published model contract - two versions, one for handing data to another company that decides how to use it and one for a supplier processing it for you. Using the published wording needs no permission. If you change the wording, you must file the contract with the regulator within 30 days of signing.High confidence
Who enforces this — and are they actually working?: The Agency for Access to Public Information, known by its Spanish initials AAIP, enforces both privacy and freedom of information. It is real and working: it has a named head, it publishes a register of final penalties that was updated on 3 July 2026, it opened a public investigation into debt-collection calls in April 2026, and it chaired an international data-protection committee in July 2026. Its 244 final penalties are mostly small, and more than half are for calling people on the do-not-call list.High confidence
How long must I keep it, and when must I delete it?: Argentina has strong floors and one hard ceiling. Anti-money-laundering rules make banks, insurers, crypto firms, accountants and estate agents keep transaction records and customer files for at least ten years. Clinical records must be kept ten years from the last entry. Banks must keep audit and accounting support data six years and produce it immediately on demand. The ceiling: credit-reporting data may only show the last five years, dropping to two years once the debt is paid.High confidence
What happens when something goes wrong?: There is no general duty to report a data breach in Argentina, checked on 18 August 2026 - the privacy law has no deadline and the regulator's security rules are recommendations, not commands. Finance is the exception and the clock is brutal: banks and registered payment firms must tell the banking supervisor within one hour of an incident happening or being spotted, keep sending updates, and file a closing report within five days.High confidence
What's the trap?: Five things bite people. Answer times are very short: ten days for an access request and five working days to correct or delete. The maximum fine is one hundred thousand pesos, about seventy US dollars, so the real risk is a shutdown order or a criminal case, not the fine. Databases still have to be registered. Publishing a map of Argentina needs government approval first. And a bank cannot run its technology and security management from abroad.High confidence
What's about to change?: Nothing is scheduled to replace the privacy law. A reform bill went to Congress in 2023 and never became law; the regulator is still campaigning for a new one. The dated thing to watch is government cybersecurity: public bodies have about 180 days from 13 May 2026 to have contingency plans and a working alternative data centre, which lands around November 2026, and a new national cybersecurity centre started issuing rules in 2026.Medium confidence
