In Spain, a valid address must match the country’s postal formatting rules. Verify that the postal code (Código postal) follows the 99999 format; it appears after street; the street name comes before the house number. The standard Spanish address structure is: Street name + house number, postal code, municipality, province.

Spain uses the postal code format 99999. Locally, postal codes are referred to as “Código postal.” The postal code structure is 5-digit: first 2 = province (alphabetical), last 3 = postal distribution units. Example address: C. Sebastián Trujillo 29, 41005 Sevilla. Postal codes are administered by Correos.

A properly formatted Spanish address follows this structure: Street name + house number, postal code, municipality, province. In Spain, the street name precedes the house number, and the postal code is placed after street. Example: C. Sebastián Trujillo 29, 41005 Sevilla.

Address validation checks format and completeness — whether an address is properly structured and meets postal standards. Address verification goes further by confirming the address exists and is linked to a real recipient. For example, validating a Spanish address means checking that the postal code (Código postal) follows the 99999 format and appears after street. Verifying it means confirming that a real recipient lives or operates at that specific address. Most businesses benefit from both: validation broadly for data quality, and verification for higher-risk situations like compliance or fraud prevention.

Bulk validating addresses in Spain means checking large volumes of records against the 99999 postal code format and 73,291 possible localities. API-based services process addresses one at a time, which introduces per-call costs, rate limits, and latency at scale. A self-hosted reference database lets you validate Spanish addresses locally with no API calls, no per-record fees, and no dependency on third-party uptime. GeoPostcodes provides 10,818 postal codes for Spain, available as a downloadable dataset for direct integration into your validation pipeline.

Spain has 10,818 postal codes (Código postal), covering 73,291 localities across 8,681 administrative regions. Postal codes follow the 99999 format. They are administered by Correos. GeoPostcodes maintains this dataset with regular updates as postal codes are added, merged, or retired.

Postal codes in Spain are not static — Correos periodically adds, merges, and retires codes as populations shift and administrative boundaries are redrawn. With 10,818 active postal codes across 73,291 localities, even small changes can affect address validation accuracy. Businesses that rely on Spanish address data should use a regularly updated reference database rather than a one-time export to avoid mismatches over time.
