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

United KingdomChecked 18 August 2026

Yes, with paperworkWork: HighEnforcement: Active

In one paragraph: Data can leave the United Kingdom, but you need the right paperwork first. Sending it to Europe or to about fifteen other approved places needs nothing extra. Anywhere else needs a government-published contract and a risk check. No general law forces data to stay in Britain. The privacy regulator is busy and its fines are getting bigger.
The catch: The easy headline stops being true in three places. Telecoms operators must keep backup copies of key network information inside the United Kingdom. National Health Service patient records may only be sent to countries the United Kingdom has formally approved, which rules out the standard contract route. And government material classified SECRET or above cannot sit in public cloud at all. Everyone else can store data abroad with the right contract in place.
Does this apply to me?: Yes. British privacy law reaches a company anywhere in the world if it deliberately offers goods or services to people in the United Kingdom, or watches what they do online. There is no size or revenue floor to hide under. If you are caught and have no British office, you generally have to name a representative in the United Kingdom, unless you are a public body or your processing is rare and low risk.High confidence
Can the data leave the country?: Yes, with paperwork. The United Kingdom has no general law forcing data to stay in the country. Send it to the European Economic Area or another approved country and you need nothing extra; send it anywhere else and you need an approved contract plus a written risk assessment. Three industries are stricter: telecoms, the health service and classified government work. Banking, payments, insurance, securities, education, online gambling and mapping have no location rule that we could find.High confidence
What do I have to do to send it abroad?: The model is an approved-list one. If the destination is on the government's approved list you may send data with no extra paperwork. If it is not, you must sign the government's own contract template and run a risk assessment first. The list is well populated: the whole European Economic Area plus Andorra, Argentina, the Faroe Islands, Gibraltar, Guernsey, the Isle of Man, Israel, Jersey, New Zealand, South Korea, Switzerland and Uruguay, with partial cover for Canada, Japan and the United States.High confidence
Who enforces this — and are they actually working?: The Information Commissioner's Office, and it is very much working. It fined Capita fourteen million pounds (about $18 million) in October 2025, Reddit £14.47 million (about $18.5 million) in February 2026, and the owner of Imgur in the same month, and it issues smaller marketing fines almost monthly. Watch a quirk: a replacement body called the Information Commission legally exists but had no staff and did no work in its first financial year, so the old office is still the one that acts.High confidence
How long must I keep it, and when must I delete it?: There is no single deletion deadline. The rule is that you keep personal data only as long as you actually need it, and you must be able to explain the period you chose. Pulling the other way are minimum keeping periods: company and tax records for six years, telecoms connection records for up to twelve months if the government serves a notice, and telecoms security data for thirteen months. Where a minimum and a maximum clash, the legal duty to keep wins and you keep the data.High confidence
What happens when something goes wrong?: Count at least three clocks. Any organisation has 72 hours to tell the privacy regulator about a personal data breach, and must tell the affected people if the risk to them is high. Telecoms and internet providers also have 72 hours under the electronic communications rules — that used to be 24 hours and quietly changed on 20 August 2025. Operators of essential services such as water, energy and transport have their own 72-hour clock to their own regulator.High confidence
What's the trap?: Five. (1) A child can consent at 13 here, not 16 — but the children's design code covers everyone under 18, and the regulator fined Reddit £14.47 million (about $18.5 million) for weak age checks. (2) Telecoms firms must keep some backup data physically in Britain. (3) Health service data can only go to approved countries, so the standard contract does not help you. (4) Misusing personal data can be a crime, not just a fine. (5) The government can secretly order a company to weaken its security, and Apple is fighting one of those orders right now.Medium confidence
What's about to change?: Two things to watch in the next twelve months. A cyber security bill is going through Parliament and will widen incident reporting to data centres and managed service suppliers — it is not law yet, so do not plan as if it were. And the privacy regulator is due to be replaced by a new body called the Information Commission, but only once ministers lay the paperwork, which had not happened by mid-2026. The regulator is also writing a statutory code on artificial intelligence.High confidence
