Sending Airmail from UK to Gibraltar: Step-by-Step Guide

Mailing to Gibraltar from the UK is straightforward but has specific requirements. Follow these steps for reliable delivery.

Step 1: Verify Address Format

Gibraltar addresses use UK-style formatting but with "GIBRALTAR" as the country line:

Recipient Name
Street Address / Building Name
Town Area (e.g., "Gibraltar")
GIBRALTAR
Postcode: GX11 1AA (format: GX11 1AA)

No "UK" or "Spain" in address. Postcodes all start with GX11.

Step 3: Choose Service & Buy Postage

Buy online (Royal Mail website/Click & Drop—cheaper), at Post Office, or via franking machine. Print label on A4 or use integrated labels.

Step 4: Prepare Envelope
