How to Address an International Letter to Spain

Spain uses a five-digit postal code system for mail delivery. The postal system, operated by Correos, covers urban, suburban, and rural areas across Spain, including major cities such as Madrid, Barcelona, Seville, and Valencia. Post Office Boxes (P.O. Box) are widely used, particularly in larger cities. This guide provides the correct formats for residential, business, rural, PO Box, and military addresses, along with special considerations for government offices, NGOs, and courier services.

Standard Address Format in Spain

The typical format for addressing a letter to Spain includes the following elements:

1. Recipient Name: The full name of the person or business receiving the letter.
2. Street Address or PO Box (Apartado de Correos): The recipient’s street address or Post Office Box number.
3. Postal Code and City/Town: The five-digit postal code, followed by the city or town name.
4. Province (Optional for Large Cities): For smaller towns, include the province name to help with sorting.
5. Country: Always include “SPAIN” in capital letters on the last line for international mail.

Detailed Format Breakdown

1. Recipient Name
   The recipient’s full name should be written on the first line. For business addresses, include the company name first, followed by the recipient’s name or department.

   Attn: María García

2. Street Address or PO Box (Apartado de Correos)
