I started the previous thread about experiencing delays when shipping stuff from Canada to the USA. In the current situation it turns out that US customs rejected or had some sort of problem with the EIN number of the recipient (in this case, the Dorn VA medical center in Columbia SC). So we're trying to work with the recipient to put the correct EIN number in the hands of US customs. This isin't the first time we had to scramble to get an EIN number that US customs didn't have a problem with. Does anyone know just what is it about any given EIN number that US Customs has issues with? The digits don't add up? What I'd really like to know is -> in the future, is there some way we can "test" the recipient's EIN tax number to see if it's acceptible to US customs *before* we ship the item?
