should customer number be unique ?

[nickon2]

Hi,

I am using vm2 version 2.0.22d on a joomla 2.5.11 installation with php version 5.3.25.
I notest that since some registrations back (don't know from which vm version ) the customer number is the same as the previous one.
I was under the impression that this should be unique?
Anyone has more info about this ?

Kind Regards

Are you saying that update killed some customers?
