Caution
To enhance the security of your application, we have upgraded to a new key system. Please apply for the new version immediately to ensure uninterrupted service and safeguard your application's integrity. Amap’s coding tables are periodically updated, so the data provided on this page should be used for offline reference only and should not be cached or relied upon in production environments. To maintain system compatibility, avoid hardcoding numerical identifiers directly into your programs. Instead, dynamically retrieve the latest adcode using online services such as geocoding or reverse geocoding APIs.
