This is example of URL http:// xyzcom/City/cabs-in-jodhpur--89.aspx
on my website all the URL have same kind of Extension ( --00.ASPX ),
If these extensions have some value in searches same like zip codes then it has no harms otherwise if it is crap like eCommerce store SKU So you need to remove it
no it's not a Zip code its just a number which help us to find the cities with that numbers.
So you should remove this
