What are the postcodes for South Georgia & South Sandwich Islands?South Georgia uses SIQQ 1ZZ. South Sandwich Islands have no permanent population and thus no postcode; mail must be routed via British Antarctic research stations.

How long does mail take to arrive?Typically 2-6 months. Mail routes via UK → Falkland Islands → Antarctic supply ships (only 3-4 voyages/year), heavily impacted by weather.

Can I send packages?Only small letters/postcards (<500g) are accepted. Prohibited items include perishables, medicines, batteries. Prior permission from authorities is mandatory.

How to format the address?Example: Name / [Recipient Unit, e.g., Research Station] / South Georgia Island / SIQQ 1ZZ / British Antarctic Territory (must be in English).

Is mail loss common?Very high risk! Due to extreme logistics. Use tracked services (e.g., DHL) for critical items and purchase postal insurance.
