Paraguayan addresses are written in Spanish and lean on the city and department, with a postal code that is often left off. When a code is used, the traditional form is four digits, though many senders still skip it. Here is the correct structure, a real example, and the mistakes that cause failed deliveries.
A Paraguayan label is recipient, optional company, the street with its number, then the postal code and city on one line, then the country. Add the department for addresses outside Asunción, and write the address in Spanish.

Mariscal López 1234 street name first, then the number, Spanish style1536 Asunción four-digit code first, then the city; the code is optionalPARAGUAY required for inbound international shipmentsPostal codes are not deeply embedded in Paraguayan addressing. Correo Paraguayo maintains a code scheme, and Asunción falls in the low 1xxx range, but many customers and couriers route entirely on the city and department. Treat the code as helpful rather than decisive, and never let a missing code block an otherwise complete address.
The country-specific rules that generic autocomplete and single-line address fields tend to get wrong.
Postal codes are not consistently used in Paraguay, and many valid addresses arrive without one. A checkout that makes the code mandatory will reject legitimate orders, so treat it as optional and route on the city and department.
Asunción is the capital district and stands on its own, but everywhere else the department (such as Central, Alto Paraná, or Itapúa) is what separates same-named towns. Omitting it leaves the destination ambiguous.
The traditional Paraguayan postal code is four digits, such as 1536. Correo Paraguayo has published a longer numeric code, so a validator should accept the short form without demanding the expanded one.
Write the street name, then the number: Avda. Mariscal López 1234. Abbreviations like Avda. and c/ (casi, for a nearby cross street) are common, and a number-first order reads as an unknown address.
Each of these passes a basic "is this field filled in" check but fails at the carrier, turning into a redelivery, a return, or an address correction fee.
