Quick answer: No, US citizen children do not need a passport to travel to Puerto Rico. Puerto Rico is a US territory, so flying there from the mainland is a domestic flight. The TSA does not require children under 18 to show any ID at all when flying with a parent or adult companion within the United States.
Do kids need a passport for Puerto Rico?
If your child is a US citizen and you are taking a flight that begins and ends inside the United States or its territories, the answer is no. Puerto Rico, the US Virgin Islands, Guam, American Samoa, and the Northern Mariana Islands all count as domestic travel. Your child does not need a passport, a passport card, a REAL ID, or any government-issued ID to board a flight with you.
What ID does my child need at the airport?
Nothing official. TSA does not require any ID for travelers under 18 when they are accompanied by an adult companion. The adult’s REAL ID-compliant license or passport is all that is needed at the security checkpoint. Many parents do still bring a copy of the child’s birth certificate or an insurance card in their luggage in case they need to verify the child’s identity for medical reasons, but TSA itself will not ask for it.
What about unaccompanied minors?
Airlines, not TSA, set the ID rules for kids flying alone. Most major US airlines accept a birth certificate, school ID, or passport for unaccompanied minor service. Each airline has its own unaccompanied minor program with required forms, fees, and age limits, usually 5 to 14 years old. Contact your airline directly before booking a solo flight to Puerto Rico for your child.
Do kids need a passport for a cruise from San Juan?
It depends on the cruise. On a closed-loop cruise that starts and ends in San Juan and only visits other US ports or certain Caribbean stops, US citizen children typically only need a certified birth certificate plus a government-issued photo ID for kids 16 and over. Children 15 and under can usually board with just a birth certificate. On a cruise that starts in San Juan and ends in a different country, or that visits a non-approved port, every passenger including children must have a passport book.
Always check the documentation requirements with your specific cruise line, because some cruise lines require passports for all passengers regardless of itinerary, especially for emergency disembarkation in a foreign port.
Should I get my child a passport anyway?
A passport book or passport card for your child is optional for Puerto Rico travel but useful for several reasons. A passport card costs $15 less than a book for minors, gives you a backup ID if a birth certificate is lost or damaged, lets your family take a quick cruise to the Bahamas or Mexico without scrambling for documents, and works as ID at the ER or for medical paperwork while traveling. Child passport books cost about $135 and child passport cards cost about $65 as of early 2026, both valid for five years.
Both parents must apply in person for a child’s passport
This is the rule that catches families by surprise. For any passport applicant under 16, both parents or legal guardians must appear in person at the passport acceptance facility with the child, or the absent parent must submit a notarized DS-3053 statement of consent. Bring the child’s certified birth certificate, both parents’ photo IDs, the child’s passport photo, and the application fee. Routine processing takes 4 to 6 weeks and expedited takes 2 to 3 weeks.
