A booklet listing the postal numbers may be obtained from any post office. Please, note that the names of the municipalities in Flanders must be written in Dutch, while those of Wallonia must be in French. For the Brussels agglomeration, addressing may be done either in Dutch or French. When looking up someone's telephone number, you must first find out in which village or city the person lives. There is a list of all Belgian municipalities in each volume of the telephone directory, with the corresponding volume number and principal town printed next to each entry.
Every zone has an area code.
From July 1st 2000, you have to dial the area code even when making phone calls within the area. For international phone calls prices vary according to the country. The column with 'Land van Bestemming' shows you all the countries of destination. Portulaca is selling WorldxChange phone cards that offer substantial reductions to these fares. The offices are open every working day from 9am until 5.15pm.
