To fly, the type of ID needed depends on the kind of flight (domestic or international) and the country.

For Domestic Flights (e.g., within the US or Canada):

• Adults (18+) generally need a valid, government-issued photo ID that includes their full name and date of birth.
• In the US, starting May 7, 2025, a REAL ID-compliant driver's license, or another TSA-accepted form of ID, is required for domestic flights. A REAL ID is indicated by a star on the card.
• Other accepted IDs include U.S. passports, military IDs, permanent resident cards, border crossing cards, and certain tribal IDs.
• If you don't have your ID, it is sometimes possible to fly after completing an identity verification process with TSA, but this can take extra time and is not guaranteed.
• Children under 18 often do not require ID when flying domestically if accompanied by an adult with proper ID.

For International Flights:

• A valid passport from your country of citizenship is required.
• Visas may also be necessary depending on the destination.
• Some regions accept national identity cards (such as EU/EEA/Swiss ID cards) for travel within those areas.

Examples of Acceptable IDs for Domestic Flights:

• REAL ID-compliant driver's license or state ID
• U.S. passport or passport card
• DHS trusted traveler cards (e.g., Global Entry, NEXUS)
• Military ID
• Permanent resident card
• Canadian provincial driver's license or Indian and Northern Affairs Canada card

Important Notes:

• Expired IDs are usually not accepted.
• Temporary or digital copies of IDs are often not accepted.
• Plan to arrive at the airport early if you have issues with your ID.

This summary covers typical ID requirements for flying, particularly focusing on the US and Canada as examples. Requirements may vary by country and airline. Always check with your airline and local government before traveling.
