Message

Possible causes and recommended actions

Three-factor identity verification

101

Authentication passed

The call was successful.

201

Authentication failed. The name and ID number do not match.

The user's information may be incorrect or fraudulent. Ask the user to confirm the information and retry the operation.

202

Authentication failed. Possible match.

The person's appearance may have changed significantly, or the photo quality is poor. Provide an option for manual review or ask the user to upload a new photo.

203

Authentication failed. No photo in the database.

This may be caused by an issue with the authoritative data source. Provide an option for manual review.

204

Authentication failed. Not the same person.

The person in the photo may not be the same individual, or the photo quality is low. Handle this case as needed. If the person is the same, ask them to retry the operation.

205

Authentication failed. Failed to create a model from the image for comparison.

The quality of the portrait photo may be too low, which prevents the face detection or feature extraction algorithm from creating a model. Ask the user to take a new photo. Ensure that the photo is a front-facing view with even lighting and a clear face.

206

Authentication failed. Incorrect image format.

The uploaded image file format is not supported. Convert the image to a common format such as JPG or PNG and upload it again.

207

Authentication failed. The uploaded image is too small. Upload a new image.

The resolution or file size of the uploaded image is below the minimum system requirement. Upload a higher resolution image and ensure that the face area has sufficient pixel detail.

208

Authentication failed. The quality of the uploaded portrait photo is poor. Upload a new photo.

The overall quality is substandard. This may be due to issues such as blur, high noise, excessive compression, or facial occlusion. Upload a clear, front-facing, and unobstructed portrait photo.

301

No record found. The ID number is not in the database.

The ID number does not exist in the authoritative data source. Ask the user to confirm that the ID number is correct. If the issue persists after confirmation, it may be an issue with the coverage of the authoritative data source. Provide an option for manual review.

302

No record found. Cannot be verified.

This may be due to a timeout from the authoritative source's API, temporary unavailability of the data source, or an abnormal status of the identity information in the authoritative source. Ask the user to retry later. If the issue persists, guide the user to manual review.
