巴西联邦共和国，是拉丁美洲最大的国家，人口数居世界第五。领土位于中南美洲与大西洋之间，国土面积为世界第五大，仅次于俄罗斯、加拿大、中国与美国，与乌拉圭、阿根廷、巴拉圭、玻利维亚、秘鲁、哥伦比亚、委内瑞拉、圭亚那、苏里南、法属圭亚那接壤。巴西的国内生产总值位居南美洲第一，世界第十。由于历史上曾为葡萄牙的殖民地，巴西的官方语言为葡萄牙语，巴西的域名对开发美洲地区业务的企业还是有实用价值的。巴西域名注册

南美的巴西域名注册可以讲比较乐观但也有难，虽然多年来只注册了三个巴西域名但还算是成功的，巴西域名二级域名不下几十种,但最常用的还是.com.br等，注册要求比较宽松但还有要提供相应资料、成功率高。.br is the Internet country code top-level domain (ccTLD) for Brazil. It was administered by the Brazilian Internet Steering Committee until 2005 and now it's administered by Brazilian Network Information Center . A local contact is required for any registration. Registrations of domain names with Portuguese characters are also accepted. Except possible for universities, the second level domain is fixed and defines the category. For example, site.art.br is in the art category, and othersite.org.br is in the Non-governmental organization category. Institutions of third level education were allowed to use the second level domain and .edu.br, although some use .com.br. There are also some other few exceptions that were allowed to use the second level domain until the end of 2000. As of February 2007, most domain registrations ignore categories and register in the .com.br domain, which has over 90% of all registered domains.

.br is the most common Portuguese language Web site suffix
