I am trying to call the Aduana office in Mexico from the US.
The numbers listed on their website are:

01 (55) 58 02 15 63, 01 (55) 58 02 20 01 o 01 800 22 38 262

I am not gettin through and I figure I am not dialing everthing right. Can anyone help me figure out what numbers I need to add to these numbers to be able to call from the States?

Thanks,
Scott
