What is the Gibraltar postcode?

Short answer

Gibraltar's postcode is GX11 1AA. The whole territory shares this single postcode, so every address in Gibraltar uses it.

Detailed answer

Every address in Gibraltar uses the same postcode, GX11 1AA. There are no separate postcodes for different streets or districts. The Royal Gibraltar Post Office divides Gibraltar into internal delivery districts, but these are not used in addresses.

Gibraltar has its own postal service, the Royal Gibraltar Post Office. It is not part of Royal Mail, so post between the UK and Gibraltar travels as international mail.

The postcode exists mainly so that Gibraltar addresses are accepted by online forms and international retailers that require one. It is not needed for local mail within Gibraltar.

Filling in online forms

  • Enter GX11 1AA in the postcode field.
  • Choose Gibraltar as the country if it is offered.
  • If the form asks for a county, state or region, enter Gibraltar.
  • If a retailer only lists UK countries, check its international delivery terms before ordering. Gibraltar is a separate territory for customs purposes and some retailers do not deliver here.

Customs charges on parcels

Since 15 July 2026, when the UK/EU Treaty arrangements began to apply provisionally, Gibraltar's import duty has been replaced by a Transaction Tax on goods. The standard rate is 15% in 2026, with reduced and zero rates for some goods.

The thresholds and handling fees for personal parcels may differ from the rules that applied before the Treaty, so check with the Royal Gibraltar Post Office or HM Customs Gibraltar before ordering higher-value items.
