Stamps can be bought from post offices (generally open weekdays 9-5:30, Saturday 9-noon), from stamp machines outside post offices, and from newsagents' stores and newsstands. Mailboxes are known as post or letter boxes and are painted bright red; large tubular ones are set on the edge of sidewalks, whereas smaller boxes are set into post-office walls. Allow seven days for a letter to reach the United States. To contact the post office by phone, call the main office at 08457/740-740. Check the Yellow Pages for a complete list of branches, though you cannot reach individual offices by phone.
