numeric number removing possibility in lisitng

I see a numeric number like number ’27’ in this link http://eyellowpages.pk/directory/27/solution-house/ in my every listing. Is there any possibility to remove or replace this number with tags/category?

Thanks for creating such a useful plugin. Anxiously waiting for your kind reply.

Thanks,
Mansoor Chohan
