There are more than 6,200 post offices across the country, a combination of corporate offices and private franchises that are operated by retailers, such as drugstores. In terms of area serviced, Canada Post delivers to a larger area than the postal service of any other nation, including Russia (where service in Siberia is limited largely to communities along the railway). As of 2004, nearly 843,000 rural Canadian customers received residential mail delivery services.[7]
