Error bad character content for element 'avs_zipcode'

I'm having a problem with the validation of the zip code.

If my zip code is longer than 9 character, I received "Error bad character content for element 'avs_zipcode' but the document say that there is a maximum of 30-character alphanumeric. (https://developer.moneris.com/Documentation/NA/E-Commerce%20Solutions/API/Purchase)

The zip code I use is: 1234567890, without any space. I know it's not a valid one, but I though the transaction would pass, but the validation of the zip code would fail, butthat not what happen.

The error occur when I do an ResPurchaseCC with the .net api

The order id of the transaction with that error is SMD43609_157454

 

Thank you
