A postcode is made up of an area, district, sector and unit code. The area code is the first two letters of the postcode. It indicates the city or region of the location. The sector code is the third section of the postcode. It is a number that indicates what street the property is on. Let's look at some tools that can help you create a postcode area map or postcode sector map. Both can be helpful for business planning or improving marketing strategies.
