jumping the border

[tone loc]

i just recently bought a engine and trans from canada and they just recieved my payment today. he calls me up so i can repeat my info and then he asks for my social securtiy #. He told me it was for customs so they know were the engine is going. So like a piece of shit i told him without thinking twice. Is this true that he needs my ss# and if its not what should i do to protect myself? Im only 15 so i dont think he will be able to use it yet but what happens in 3 years? thanks for the help and save the "you fucked up" comments. thanks
