A system for contact information discovery and discovery-based label updation comprising:

• a non-transitory storage device having embodied therein one or more routines operable to facilitate contact discoveryand discovery-based label updation;
• and
• one or more processors coupled to the non-transitory storage device and operable to execute the one or more routines, wherein the one or more routines include:
