description: Use PostGrid's China Premium Dataset to verify Chinese addresses down to building level (P4 coverage) via the useEnhancedChinaDataset query parameter.
---

Our International address verification `POST intl_addver/verifications` offers P3 coverage for Chinese addresses, which verifies down to street-level. The China Premium Dataset offers P4 coverage and provides enhanced verification down to building-level when `useEnhancedChinaDataset=true` is provided as a query parameter.

You can learn more about verification coverage and match level [here](/address-verification/international-address-verification-and-autocomplete#verification-match-level/index.md).
