What API contains
ICAO says API is generated during check-in. It identifies a passenger through data such as full name, date of birth, sex, nationality and travel-document details. Most of this information comes from the machine-readable zone of a passport 1.
The EU list in Regulation (EU) 2025/12 includes the passenger's names, date of birth, sex, nationality, document type and number, issuing country, document expiry date and PNR locator. Where available, it can include seat and checked-baggage details. The flight portion includes the flight number, departure and arrival airports, and local departure and arrival times 4.
How PNR is different
PNR is made during booking and kept in the airline's reservation system. ICAO says it can contain a name, itinerary and ticket indicator, and may hold contact, payment, seat, baggage and service information. The amount differs between airlines and bookings 1.
API is a defined identity and flight dataset. PNR can show how a journey was booked and changed. Regulation (EU) 2025/13 joins API with other PNR data for the prevention, detection, investigation and prosecution of terrorist offences and serious crime 5.
Why governments receive it before travel
The UN Security Council adopted Resolution 2396 on 21 December 2017. Paragraph 11 requires UN member states to develop API systems and use the data to stop the travel of foreign terrorist fighters. Paragraph 12 requires states to develop the ability to collect, process and analyse PNR data, with respect for human rights and fundamental freedoms 2.
ICAO's Annex 9 Standard 9.7 says each state must establish an API system. Standard 9.8 requires a legal basis and consistency with international API standards. The ICAO passenger-data guidance says advance transmission lets border agencies run targeted controls before the traveller arrives 1,3.
What the EU rules say
Regulation (EU) 2025/12 covers API for external border checks. It requires air carriers to collect API for passengers on flights into the EU and send it through an EU router to competent border authorities. The regulation limits the dataset to the passenger and flight fields set out in Article 4 4.
Regulation (EU) 2025/13 covers API and PNR for terrorist offences and serious crime. It applies to extra-EU flights and to selected intra-EU flights. Both regulations entered into force on 28 January 2025. Most operational duties depend on the EU router becoming operational and later application dates in the regulations 5,6.
What this means for a traveller
- Your airline may scan the machine-readable part of your passport or ask for the same details during online check-in 1,4.
- A carrier may have to send a manifest before departure and receive a response from a border authority 1.
- API does not replace a visa, travel authorisation or arrival card. Those are separate entry requirements 1.
- Data rules differ by country. Check the privacy notice for the government system that receives your information.
Common questions
Is API the same as an arrival card?
No. API is normally sent by the carrier from check-in and flight records. An arrival card is a separate declaration made by the traveller 1.
Is API the same as PNR?
No. API mainly identifies the traveller and flight. PNR is the airline booking record and may contain itinerary, contact, payment, seat and baggage information 1,5.
Can API include my passport number?
Yes. ICAO and the EU rules list travel-document data, including the document number and issuing country 1,4.
Why is API sent before arrival?
It gives border authorities time to check passengers before the flight arrives and, in some systems, before boarding 1,2.
What is the international legal basis?
ICAO Annex 9 contains the aviation standard. UN Security Council Resolution 2396 requires member states to develop API and PNR capabilities for the stated security purposes 2,3.
