User:Sputink/sandbox/List of postal codes in Tanzania

Postal codes in Tanzania were initiated by the Tanzania Communications Regulatory Authority (TCRA) on 22nd June 2012. Tanzanian Postcodes consist of 5 numbers, the first two being the code for the region and the last three pinpointing the ward within the region.

Due to practical reasons the postal codes are not divided equally by region however they are distributed by the population density of each region. Most regions only have one two digit prefix, however Dar-es-salaam is the only region with four (11xxx,12xxx,14xxx,15xxx)
