Documents Required for Children Entering Mexico
We therefore highly recommend that children carry a passport regardless of age or requirements and that you carry authorizations letters, custody papers and any other document you feel may be requested by officials.
Mexican law requires any non-Mexican citizen under the age of 18 carry notarized written permission from a parent or guardian not traveling with the child to or from Mexico. This includes children traveling with only one parent. This permission must include the name of the parent, the name of the child, the name of anyone traveling with the child, and the notarized signature(s) of the absent parent(s).
The US State Department recommends the permission include travel dates, destinations and a brief summary of the circumstances surrounding the travel. The child must be carrying the original letter – not a facsimile or scanned copy – as well as proof of the parent/child relationship (usually a birth certificate or court document) – and an original custody decree, if applicable. Travelers should contact the Mexican Embassy or closest Mexican Consulate for current information.
A similar letter allowing the person bringing the child into Mexico to make medical decisions for the child in the event of a medical emergency is also a good idea.
Exceptions to this rule:
Sample Letter of Authorization for Travel

I (parent’s name), authorize my child/children, (child/children’s name) to travel to (destination) on (date of travel) aboard Airline/Flight # (flight information) with (accompanying adults), returning on (date of return).

Passport
By far a passport is the best document to carry for identification into Mexico. We highly recommend a passport for children – regardless to whether it is required – when traveling with kids.
Via Air
Children must now produce a passport when entering Mexico by air.
Via Land or Sea
Canadians or Americans 16 and older are required to carry a passport or a passport card.
Children up to the age of 15 may present proof of citizenship alone; birth certificate, a consular report of birth abroad, a naturalization certificate, or a Canadian citizenship card.
