Money transfers via MoneyGram system can be used as by bank customers, and by people who do not have bank accounts. Money transfers can be claimed within 45 days, but if for some reason, this period is exceeded, the processing operator would need additional time to call the main office of the company of MoneyGram for voice authorization. In the city of San Salvador representatives of MoneyGram and Citibank announced a new regional project, which will provide money transfer services in Costa Rica, El Salvador, Guatemala, Honduras and Nicaragua. MoneyGram hired compliance officers in many of their global offices to ensure compliance with regulations of specific countries or regions. In March 2012, the company MoneyGram merged with the network of U.S. payment centers ZipZap.
