Postal Code 5609 – King William'S Town,

Postal Code 5609 for King William'S Town is part of the South Africa postal code system, which uses a numeric code of 4 digits (e.g. 0083). Addresses here are organised as Province → Municipality / Locality → Suburb.

No building-level records are held for this code in the imported dataset, so only the code and its location details are shown. The absence of records does not mean the postal code is unused.

Couriers, e-commerce checkout forms and address autocomplete tools all rely on the postal code to route mail and to check that a stated address matches the code. Because a postal code identifies a delivery area rather than a single building, two addresses that share the same code can still be some distance apart.

Always write South Africa Postal Code in full when completing a form, including any leading zero. Enter a 4-digit South African postal code.
