I have a table for storing the postman coverage area. It has two fields

postmanid
covering_pincode

What i am going to implement is, when a user enters a pincode in the textbox, the list of the postman covering that pincodes are displayed.

My doubt is, how can i enter the values in the table

1. Multiple pincodes stored in single row like  
postmanid->1, covering_pincode-> 626123, 626124, 626432, 654564

OR

2.Storing each pincode by each seperate fields like 

postmanid->1, covering_pincode->626123,
postmanid->1, covering_pincode->626124,
postmanid->1, covering_pincode->626432, 
postmanid->1, covering_pincode->654564

Please help which one is best for searching the table by pincode
