Passenger data

Data protection laws by country

Most countries now have a general data protection law. UNCTAD counts 137 of 194 countries with such legislation 1. These laws set rules for how passport, biometric and passenger data is collected and kept. Border and police work often sits under separate rules or exemptions. The EU GDPR, for example, does not cover criminal law enforcement by competent authorities 3. Some countries have a law on the books but no working regulator yet 2.

How many countries have a data protection law

UNCTAD tracks data protection laws around the world. Its tracker says 137 out of 194 countries have put legislation in place. It gives regional shares of 61 percent for Africa and 57 percent for Asia. Among least developed countries the share is 48 percent 1.

A law on paper is only part of the picture. A regulator needs staff, funds and legal powers to act. The table below notes where a law exists but its regulator has not been set up, as of 19 October 2026 2.

Country table

The table draws on the DLA Piper Data Protection Laws of the World country pages, checked on 19 October 2026, and on national government and press sources where DLA Piper has no page 2. It covers the general law and the main regulator. The last column notes a rule that bears on border or travel data where we found one. Laws change often. Check the national regulator before relying on any entry.

Where a law exists but no regulator is active

Several countries have passed a law and not yet set up the body that enforces it. People there may hold rights on paper with no body to enforce them 2.

  • United Arab Emirates: the 2021 federal law names a Data Office. DLA Piper reports it had not been set up when it last updated its page 2.
  • DR Congo: the 2023 Digital Code calls for a Data Protection Authority created by decree of the Prime Minister. No such decree had been adopted when DLA Piper last updated its page 2.
  • India: the 2023 Act creates a Data Protection Board. The government was still setting it up after a notification of 13 November 2025 2.
  • Bangladesh: the 2025 ordinance is in force on paper. The national authority meant to oversee data was described as proposed in November 2025 11.
  • The Gambia and Sierra Leone: neither had a data protection law confirmed in force as of the latest sources we found 12,13.

What these laws mean for border and travel data

Border systems handle some of the most sensitive data a state holds. This includes passport details, fingerprints, face images and travel history. General data protection laws often apply to airlines, airports and private contractors. Rules for border police and immigration staff can differ 2,3.

The EU has border-specific laws on top of the GDPR. The PNR Directive requires airlines to send passenger name record data to national Passenger Information Units for flights between the EU and non-EU countries. States may add flights inside the EU. The Directive sets a five-year retention period, with data masked after six months. It bans processing of data that reveals race, ethnic origin and other sensitive traits 4.

The EU Entry/Exit System registers non-EU short-stay visitors at the external borders of 29 countries. It records names, travel document data, fingerprints and face images, and replaces passport stamps. Operations began on 12 October 2025 and the system was fully running on 10 April 2026 7. The EES Regulation says data on travellers who kept to their permitted stay is kept for three years. Data on overstayers is kept for five years 6.

In the United States, Customs and Border Protection uses face comparison at entry and exit. CBP says US citizens may ask for a manual check instead. It keeps their photos no more than 12 hours. Non-citizens in scope are enrolled in the DHS biometric system called IDENT 9.

Law enforcement and national security exemptions

Almost every data protection law carves out police and security work in some way. The GDPR does not apply to processing by competent authorities for the prevention, investigation, detection or prosecution of crime, or for threats to public security 3. A separate EU law, the Law Enforcement Directive (EU) 2016/680, covers that work. The UK copied it into Part 3 of its Data Protection Act 2018 2.

Brazil's LGPD excludes public safety, national security, defence and criminal investigation. A specific law is meant to cover these areas 2. India's 2023 Act lets the central government exempt notified state bodies in the interest of sovereignty, security of the state and public order. Core duties are lifted where data is processed to prevent, detect or prosecute offences 10.

Courts have tested these exemptions. In the UK, the3million and the Open Rights Group challenged the immigration exemption in the 2018 Act. The Court of Appeal found it unlawful in 2021. The Government amended it. The High Court found the new version unlawful in March 2023 and the Court of Appeal upheld that ruling on 18 December 2023 8.

In the EU, the Court of Justice ruled on the PNR Directive on 21 June 2022 in case C-817/19. It upheld the Directive but read it narrowly. It said blanket five-year retention for all passengers is not allowed. After six months, data may be kept only where there is objective evidence of a risk. It barred self-learning AI systems that change risk criteria without human review 5.

Who supervises EU border databases

The EU runs shared border databases such as the Schengen Information System, the Visa Information System, Eurodac and the Entry/Exit System. A Coordinated Supervision Committee within the European Data Protection Board oversees these systems. Its members are the national data protection authorities and the European Data Protection Supervisor 15.

Each national authority checks how its own state uses the data. The EDPS checks EU institutions and bodies and works with national authorities 6.

How to check the rules in your country

Start with the national data protection regulator, if one exists. Its website should list the law, guidance and decisions. For a cross-country view, the UNCTAD tracker and the DLA Piper guide are useful starting points 1,2. For border data, look for rules on passenger records, biometrics and immigration in addition to the general law. Look for court rulings on exemptions too 5,8.

Common questions

Does the GDPR apply to border police?

Not to their crime and public security work. The GDPR excludes processing by competent authorities for criminal law enforcement and public security 3. The Law Enforcement Directive covers that work 2.

Does the United States have a national data protection law?

No. DLA Piper describes US privacy law as a patchwork of federal sector laws and state laws, with no single national authority 2.

How long does the EU keep air passenger records?

The PNR Directive sets five years, with data masked after six months 4. The EU Court of Justice ruled in 2022 that keeping all passengers' data beyond six months needs objective evidence of risk 5.

What happens if a country has a law but no regulator?

People keep the rights the law gives them, but there is no body to take complaints or enforce the rules. DR Congo and the UAE are examples noted by DLA Piper 2.

Can I refuse a face scan at a US airport?

CBP says US citizens can ask for alternative processing, which usually means an officer checks documents by hand 9.
