Postal Code 1820 – Gauteng,

Postal Code 1820 for Gauteng 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.

This database holds 3 building or address records linked to this code. Each entry below is a reference from the imported source dataset rather than a verified postal address, listed so the code can be placed in context.

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. Data source: rara SA Postal Codes (snapshot: South African Postal Codes (rara)). This is a reference snapshot, not a live government feed, so confirm the code with the sender, carrier or postal authority before relying on it.
