# Get similar person

Available in VPC

This API retrieves people whose faces resemble a specified person, sorted by similarity. The search results can be used as candidates for [Merge person](/docs/en/mi-merge-persons).

              Note

              

You cannot search for similar people for those without thumbnails, as their facial feature information is unavailable. To find similar people based on a new image rather than registered images, use [Compare person](/docs/en/mi-recommend-persons-by-thumbnail).
