Im 15. can i travel to mexico without a passport?

No. Even babies need a passport.

By air? No, everyone needs a passport.

By land, you'll need picture ID and proof of citizenship (birth certificate).

Nope. Every individual needs to have a passport, regardless of age.

From the US, yes - But you need an official id from the DMV (government-issued photo ID) similar to a drivers license and a birth certificate. The rules are changing though - Soon you will need a passport to travel to Canada Mexico and the Caribbean.

You need official ID to reenter, not leave.

NO the Law requires all US Citizens that leave the country to have passports

15 AND GOING ALONE?????

PLEASE TAKE MOM OR DAD WITH YOU OR OLDER BRO. MEXICO IS NO LONGER A SAFE ZONE PLUS REGARDLESS, YOU CAN'T CROSS NOW DAYS ALONE NO MATTER WHAT. BY EXPIERENCE* I CAN NOW SAY THAT!!!!!!!!!!

A PASSPORT IS THE BEST. BUT IF YOU HAVE A STATE I.D. AND A COPY OF YOUR BIRTH CERTIFICATE, YOU'RE FINE BEING ACCOMPANIED BY THE ADULT. YOU MIGHT HAVE A WAIT DEPENDING ON THE AGENT. IF HE'S COOL,,, WELCOME BACK TO THE USA. IF HE IS NOT SOOO COOL, THEY WILL TAKE YOU TO THE SECONDARY ROOM it is ok. AND THEY WILL JUST CONFIRM YOU ARE YOU AND NOT SOMEONE USING YOUR I.D.
BEST OF LUCK.

From Canada direct flight to Mexico no passport. If you stop in the crazy USA you will need a passport.
