Why do we have the same visitor id for multiple sessions (web-traffic from different countries)?

The Adobe Visitor Id is not unique if its a combination of post_visid_high and post_visid_low then it should be unique. Can you give me an example explaining the generation of visitor id using combination of post_visid_high and post_visid_low, I see in the data the visitor id is alpha numeric ,Is there a conversion?

Also , If a person gets assigned a Adobe Visitor Id  and comes back (after few days) to visit the same page/website will he/she be assigned the same Adobe visitor Id (assuming they didn't delete the cookies). I am having issues where we cannot identify customers ,because the post_evar value is not always captured in DatawareHouse. What could be the possible reason's for an post evar value to be not captured which makes the customer unidentifiable ?

Hi ankits28281247​. Thank you for  taking time to answer this question. Appreciate all your help.

Sorry my mistake I was making up dummy data for example purposes but all the fields for the Adobe visitor Id are basically the same ,for instance  = 1f5aacf448ed89563oo555605eccc8d3 . I wasn't part of the setup years ago, but now we are trying to make sense of the existing and future data for our analytic needs.  I think the way it is setup is out of box variable is being passed to an evar is my conclusion.I might be wrong. My end goal is to identify unique visitor, which is impossible with all the discrepancies with the Adobe ID. Could you shed some light on the tracking server. I am not sure what that means.
