Recently moved to Zaragoza and discovered that the postal code system here is quite different from other European countries. Today I’ve compiled some practical information about postal codes in the Aragon region, particularly Zaragoza city, hoping to help newcomers.
Basic Structure of Zaragoza Postal Codes
Spanish postal codes consist of 5 digits, with Zaragoza city codes mainly ranging from 50001 to 50018. The first two digits 50 represent Zaragoza province, while the last three digits correspond to specific delivery areas. Central areas typically use codes like 50001, 50003, 50004, while outer new districts may use codes such as 50012, 50018.
Common Area Postal Code Reference
Here’s a compilation of postal codes for several main residential areas in Zaragoza Aragon to help you quickly find what you need when living in Zaragoza:
| Area Name | Postal Code | Main Landmarks |
|---|
| Historic City Center | 50001 | Basilica of Our Lady of the Pillar |
| University District | 50009 | University of Zaragoza |
| Delicias District | 50012 | Train Station Area |
| Actur District | 50018 | Northern Residential Area |
| San José District | 50008 | Commercial Shopping Area |
Practical Usage Tips
Postal codes are extremely important when shopping online or handling banking matters. I once made a single-digit error when ordering from Amazon, and the package was delivered to a completely different district, taking nearly a week to finally receive it. I recommend that when filling out addresses, besides the postal code, clearly write the street name and building number, so even if there’s a minor error in the postal code, the postal carrier can still locate the correct address based on the detailed Zaragoza population information.
Another reminder: other cities in the Aragon region also have postal codes starting with different prefixes - Teruel starts with 44, and Huesca starts with 22. If you need to send something to other places within the region, don’t confuse the province codes.
Postal Code Lookup Tips
The most convenient lookup method is to use the Spanish postal service Correos’ official postal code lookup tool - simply enter the street name to find the corresponding code precisely. Google Maps can also display postal code information; click on a specific location on the map and the detailed information will show the code. Personally, I frequently use a mobile app called Código Postal, which works offline and is quite practical.
