What documents do i need to travel to and from mexico?

So i'm going to Rocky Point with my friends family in 12 days for 3-4 days. I realized that i wouldn't be able to get a passport (or passcard) in time. I'm going to get state id card and bring my birth certificate, do i need any other documents?
I'm a minor btw

No need for anything else. Passports for travel by land or sea to Mexico is not required until 2009.

You will also need a notarized slip from your parents giving you permission to leave the country.

While a passport is not required yet, it soon will be.

When I went a couple of months ago, I used a drivers license and birth certificate.

I was given a hard time from the official at the border while entering Mexico. I almost thought they were not going to let me in. Eventually they did, but insisted I have a passport next time. I had no problems leaving Mexico though.

Now if you are a minor, you will also need permission signed by your parents. I would contact the Mexican Embassy to be absolutely sure what you will need to have, to avoid any problems.
