How to get the I-140 Case number?

[jmishra]

1) How to get the 13 digit I-140 Case number which can be used to check status on IVR of VSC?
2) What is the difference between RD and ND? And where to get them from?

Thanks for your help,

The EAC number is stamped on the back of your cancelled check.
