Mauritius had no postcodes until Mauritius Post rolled them out nationwide in 2014, so many customers still leave them off and rely on the locality alone. A Mauritian address is the recipient, the street, and the locality with its five-character code, then the country. Here is the correct structure, a real example, and the mistakes that cause failed deliveries.
A Mauritian label is recipient, optional company, the street, then the locality with its five-character postcode, then the country. Addresses are written in English, and there is no separate district line on the label.

So 42602 resolves to Lalmatie in the Flacq district. Because the code is recent, it is often omitted, which leaves the locality doing all the routing work.
The country-specific rules that generic autocomplete and single-line address fields tend to get wrong.
Mauritius Post introduced postcodes nationwide in 2014, so many residents still write addresses without them. When the code is missing, the locality becomes the only routing anchor, which makes an accurate town or village name essential.
Street names repeat across the island, and Royal Road runs through dozens of towns. Without a precise locality such as Lalmatie or Curepipe, a correct street name still leaves the destination ambiguous.
A Mauritian postcode is not arbitrary: the first digit is one of the nine districts, the next two are the council area, and the last two are the sub-locality. A code whose first digit does not match the district points to the wrong region.
Codes for the island of Rodrigues take a letter followed by four digits, and some localities use an extended form like 742CU001. A validator that expects only five digits will reject these valid codes.
Each of these passes a basic "is this field filled in" check but fails at the carrier, turning into a redelivery, a return, or an address correction fee.
