DPI could be the oldest computer company in Iran, established in 1957. DPI was an official branch and representative of IBM in Iran before the Islamic revolution of 1978/79, and was creatively called ``Iran Business Machines". Following a cut in commercial ties between the US and Iran in 1980, it became an independent entity, and was renamed DPI (Data Processing of Iran) in 1984.
DPI has maintained different levels of connection with IBM during the past two decades. The size of DPI alone is comparable to combined sizes of several other Iranian hardware and software companies. DPI provides a wide range of services such as total solutions on a nationwide scale, sales and rentals of mainframes and minicomputers, customer support and engineering services for mainframes and minicomputers, design, manufacture, sales, and maintenance of PCs and other hardware and peripheral parts, feasibility studies, design and implementation of application softwares, data processing services, Internet and email services, general and specialized courses in many computer fields, B.A. degree courses in computer technology, consulting services, developing MIS applications, and design and manufacture and implementation of data communication hardware and services.
DPI has several branches in Iran:
Other cities under DPI's support umbrella from Tehran or other nearest cities are: Bandar Imam Khomeini, Bandar Abbas, Bandar Mahshar, Karaj, Orumieh, Ardabil, Ghom, Haft-Tapeh, and Sar-Cheshmeh.
DPI has two major departments: Application Development, and MIS Development. DPI has 40 years of experience of ongoing activities on the informatics technology scene and offers professional services to organizations, companies, institutes, universities, and the banking network throughout the country. DPI also offers a wide range of system development as homepages and web sites, including texts, graphics, sound, animations and films, database access methods, and client/server approaches.
DPI claims that it is a pioneer in the software technology of the country, applying proficiency and experience of more than one hundred professional programmers and experts working with the application software engineering division. However more than a few newcomers always blame DPI for its slowness, use of old mainframes and having a bureaucratic and outdated system.
Several government organizations, banks and industrial companies currently are DPI customers. To name a few: Ministry of Commerce, Ministry of Health and Medical Education, Ministry of Roads and Transportation, Ministry of Industries, Iran Statistical Center, The Presidential Office, Ministry of Energy, Ministry of Oil, Bank Tejarat, Bank Sepah, Bank Saderat Iran, Agricultural Bank, Bank Melli Iran, Kerman Regional Electricity Corporation, Tehran Regional Electricity Corporation, Iran Insurance Company and TCI.
