It was only a 3 month job but it was a job at a store and I am now trying to get hired at another store and I want them to see that I have store experience...I'm lost because the number to the store is now disconnected since it was a temp store...so can I just put the store down without a number?

Uh you just put the company name, your main title and the months and yr you worked there. Well then you can explain that in the interview. Put the store name and in the interview say that the store is no longer in business.

put name of store, dates and your position. yes no number is needed
