Is there any local telephone directory of Residents in Al khobar ? Can we access that on net ?
You can use 905 which is Directory Assistance but I believe that works only for names/companies registered with Saudi Telecom ... I don't believe they will be able to help you with people living in compounds as all calls go through the compound central number unless someone has their own private line.
If you need numbers on services and companies, "Eastern Province Today" is available at Jarir and is a small directory of useful numbers.
