Gibraltar Address Format
Gibraltar follows British addressing conventions: recipient, street with house number or building name, then the locality (usually just 'Gibraltar') and postcode. Because the whole territory shares the single postcode GX11 1AA, it may be written on its own line or omitted on local mail. Overseas territories: write 'GIBRALTAR' in capitals as the destination line on international mail.
