How do postal deliveries work in Gibraltar?

Question

Accepted Answer

Post in Gibraltar is handled by the Royal Gibraltar Post Office, a separate postal administration from the UK's Royal Mail. It delivers letters to homes, rents PO boxes and issues its own stamps; UK stamps are not valid in Gibraltar, and mail between Gibraltar and the UK is treated as international post.
The Royal Gibraltar Post Office
The main post office is at 104 Main Street. Useful numbers:
Customer care: 200 75714
General counters: 200 75624
PO Boxes Unit, Irish Town: 200 72492
Mail Operations Centre and Parcel Post, Unit E, Admiral Rooke Road: 200 78364
Its website, post.gi, offers a postage calculator, track and trace, customs declaration forms, pillar box locations and PO box applications.
Home delivery
Letters are delivered to your letterbox. Gibraltar uses a single postcode, GX11 1AA, for all addresses, so the flat number, building name and street must be written clearly for mail to arrive reliably.
No parity with Royal Mail
Gibraltar is not part of the UK domestic postal network. Mail from the UK is handed over to the Royal Gibraltar Post Office, so UK domestic delivery promises and prices do not apply, and delivery times are longer than within the UK. Gibraltar stamps must be used for anything posted in Gibraltar.
Parcels
Parcels that need a signature or carry charges are held at the Parcel Post unit and you will receive a notification card. Charges can be paid online, and home delivery of held parcels is available for a fee. Since the UK-EU treaty took provisional effect on 15 July 2026, goods arriving from outside the EU, including from the UK, are subject to the new customs procedures and transaction tax, so check post.gi for the current charges.
Other services
The Post Office also provides registered and express mail, poste restante and private PO boxes for rent.
