Tanzania Address Format
Tanzanian addresses go from smallest unit to largest. Because street delivery is rare outside city centres, most mail uses a P.O. Box line; the town name followed by the 5-digit postcode appears on the last line before the country. The national addressing standard also defines a street format (house number + street or ward, then postcode + locality), but it is not yet widely used.
