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

SerbiaChecked 18 August 2026

Yes, with paperworkWork: HighEnforcement: Active

In one paragraph: Serbia copied Europe's privacy law almost word for word, so the duties feel familiar. Data can leave the country, and for most of Europe and a long list of other countries it can leave with no paperwork at all. The privacy regulator is busy — over a thousand inspections in 2025 — but it hands out warnings, not fines. The biggest fine any Serbian court imposed for a privacy breach in 2025 was about $950.
The catch: Two industries break the general picture. Online gambling operators must keep a copy of their whole player and transaction database physically inside Serbia. Banks, insurers and other financial firms cannot move any IT work abroad without telling the central bank 30 days ahead, proving the foreign country would let Serbian supervisors inspect on site, and risking a veto that forces them to cancel the contract.
Does this apply to me?: Yes. The law reaches a company anywhere in the world if it offers goods or services to people in Serbia, or watches what they do in Serbia. There is no size or revenue threshold to hide behind. If you are caught this way you must appoint a written representative living or based in Serbia, unless your processing is occasional and low risk or you are a public body.High confidence
Can the data leave the country?: Yes, with paperwork — and often with none at all. Serbia treats a very long list of countries as automatically safe: every member of the Council of Europe's data protection treaty, which covers all of Europe plus Argentina, Mexico, Morocco, Mauritius, Senegal, Tunisia, Uruguay, Cape Verde and others, and separately every country the European Union has approved. Sending data there needs no permission and no contract. Everywhere else you sign the Commissioner's standard contract or use approved group rules. Only one industry has a hard wall: online gambling. Banking has a gate rather than a wall.High confidence
What do I have to do to send it abroad?: First check the destination. If it is on the safe list, you need nothing — no contract, no filing, no approval. If it is not, you sign the standard contract the Serbian regulator published in January 2020, or you get approved group-wide rules. If you want to use your own wording instead of the standard contract, the regulator must approve it and has 60 days to answer. As a last resort there are narrow exceptions such as the person's explicit consent.High confidence
Who enforces this — and are they actually working?: The Commissioner for Information of Public Importance and Personal Data Protection, and it is genuinely working. In 2025 it finished 1,169 inspections, received 5,310 cases and issued 102 corrective orders. But it almost never fines. Of those 102 orders, 101 were warnings and one was a ban on processing. It asked the courts to punish only three organisations all year. Banks answer to the National Bank of Serbia instead, and it is fully active. A brand-new Office for Information Security exists on paper since October 2025 but we could find no sign it is running yet.High confidence
How long must I keep it, and when must I delete it?: There is no single national rule. The privacy law says keep data only as long as you need it, and each sector sets its own clock. Online gambling operators must keep every transaction for at least ten years. Phone and internet companies must keep who-called-whom records for exactly 12 months and then destroy them. Anyone selling a phone line must keep the customer's identity check for 12 months after the service ends. Financial firms must keep a live register of every outsourced service, including which countries the data sits in.High confidence
What happens when something goes wrong?: Count three clocks. Privacy breach: tell the Commissioner without delay and at the latest within 72 hours, and if you miss that you must explain why. Cyber incident: if you run an information system the state has classed as important, you have only 24 hours to report it. Then a third clock starts — updates every 24 hours for a serious incident, every three days for a middling one, and a final report within 15 days of the incident ending. Banks report cyber incidents to the central bank instead, promptly, with no fixed hour count.High confidence
What's the trap?: Five. (1) A child can consent for themselves at 15, not 13 or 16 — plan your age gates around 15. (2) A foreign court order or foreign tax authority demand for data is recognised in Serbia only if a treaty backs it, so handing data to an overseas authority on request can itself be unlawful. (3) Individuals, not just companies, can be prosecuted; the regulator has filed 49 criminal complaints since 2010. (4) Dozens of older Serbian laws still contradict the privacy law and were never fixed. (5) The government's official list of safe destination countries has not been touched since 2019 and still names a United States framework that died in 2020.High confidence
What's about to change?: One dated change and several unscheduled ones. From 1 January 2027 the ministry formally takes over supervising the new Office for Information Security, which should mean the office is actually up and running by then. A rewrite of the privacy law is being drafted by a special working group covering video surveillance, biometrics, genetic data and artificial intelligence, and a separate group is drafting an artificial intelligence law. Neither has been published as a bill, so neither is binding.High confidence
