Geotargeted QR Codes: Location-Based Routing


Geotargeted dynamic QR codes redirect scanners to different destinations based on their geographic location, enabling localised content from a single printed code.


How Geotargeting Works


    

  1. User scans the QR code, sending a request to the redirect server
    2. 

  2. The server determines the user's location via IP geolocation
    3. 

  3. Based on location rules, the server redirects to the appropriate destination
    4. 



Use Cases


Multi-language content: A product QR code redirects to the product page in the scanner's local language.


Regional offers: A retail QR code shows location-specific promotions (e.g., different discount codes by city).


Local information: A tourism QR code routes to city-specific guides and recommendations.


Compliance: Different regions may require different terms of service, privacy policies, or regulatory disclosures.

IP Geolocation Accuracy


IP geolocation has inherent limitations:


    

  • Country level: 95-99% accurate
    • 

  • City level: 70-80% accurate
    • 

  • VPN/proxy users: Located at the VPN exit, not their actual location
    • 

  • Mobile networks: May show carrier headquarters instead of user location
    • 



For critical routing decisions, consider using browser-based geolocation (GPS) with user consent as a more accurate alternative.


Combining with Language Detection


Beyond location, the Accept-Language HTTP header reveals the user's preferred language. Combining IP geolocation with language preference provides more accurate localisation:


    

  • IP says France + Accept-Language says en → English content for English-speaking visitor in France
    • 

  • IP says France + Accept-Language says fr → French content for French speaker in France
    • 



Key Takeaways


    

  • One QR code can serve different content by geography using IP geolocation
    • 

  • Country-level routing is highly accurate; city-level is less reliable
    • 

  • Combine IP geolocation with Accept-Language headers for better localisation
    • 

  • Always configure a sensible default destination for unrecognised locations
    • 

  • VPN users may be routed incorrectly — consider browser geolocation for critical cases
