But your application server can strip out spaces and dashes before you send the number to the gateway. Right?

  Of course - We do it. Wondering if anyone uses a payment gateway which prohibits this..

    how could they possibly even know you've already stripped out non-numeric characters?

      Audit. Our code is audited and certified by a security firm contracted by our merchant service provider (read bank). They don't have any such anti-transformation provision, but I'm curious to know if any payment gateway does.
