The aim of the research is an estimation of the function of postal mails demand and awareness of response by the postal service customers against mails' price hikes. During the period under study, statistics and information related to mails issued annually at the national level were examined, collected and then using the statistical methods as well as regressions, the functions in question were estimated. In this research, the documentary method was applied to identify and collect statistical data and then through direct reference to the records of the statistics of the post companies, telecommunication company, department of management and planning, as well as the central banks, data needed were collected. Using the regression models, the estimated function of the linear demand was carried out by way of minimal normal squares (ols) and minimal non linear squares (nls). Findings revealed that the postal service demand is positively and directly related with the population. Results, also, suggested that the postal service demand is a function of the national income and is found to be directly and positively correlated with it. Given the demographic natural growth and increased demand for the postal services as a result of the population growth, facilities should too, increase.
