How to handle this specific duplicate title issue

[Boxes]

Part of my website is a directory of companies. Some of the companies have mane locations in the same city.

For these listings titles and url's are like this:

1. Company ABC - Miami, FL

http://www.website.com/florida/miami/company-abc-10001

2. Company ABC - Miami, FL

http://www.website.com/florida/miami/company-abc-10002

What is the best way to fix this problem?

Thank you

Casey, thanks for the answer and this is very good idea....

but

all listings already have  full street address and phone number.

So since company name is similar, it's still appears as duplicate content. Apparently 2 extra lines of address and phone do not do the work.

Perhaps you can add more information on the companies location? You could include the Street of the location, side of town (north, east, west, south), Phone Number of the location. If each location has a specific branch name, include that also.
