Please note, the following information may only be applicable if you order your checks via thirdfort.com.

What documents can I verify?

For UK residents you can use Thirdfort's Identity Document Verification check to verify the following ID documents:

Passport
Drivers License
National ID Card
Residence Permit

A full list of all internationally supported ID documents can be found here.

What kind of file should I upload?

To get the most from Thirdfort’s Identity Document Verification check we recommend that you upload a photo that you (or your client) has taken of the document. Ideally, the photo should be in JPEG or PNG format. This will ensure the highest quality image, and remove the risk of pixel distortion that can occur with some document scanners.

Please only submit images in colour. Black and white images can obscure security features, making it harder for us to provide a confident fraud assessment of your document.

How to take the best quality photograph

When taking a photo of your client’s document, please ensure that:

There is no blur or glare distorting the information on the document.
All four corners of the document are equally visible in the photo.
None of the features on the document are obscured, including the MRZ* and document number

*The two lines of code that can be found at the bottom of a passport and some other ID documents.

Good quality image

✅ All four corners of the image are visible

✅ All of the printed text is visible and clear

Poor quality image

❌ The text or security features are distorted by glare

❌ The document is cropped

Breakdown of results

Here is a breakdown of the most common flags on an Identity Document Verification check report. If you are still unsure about the reason for a flag after reading this, please raise a query with the Client Support team for them to investigate. You can reach them via the live chat in the corner of this page.

Flag Category & Sub-category	Reason for flag
Visual Authenticity	Checks the authenticity of the document in line with its security features and fonts.
Original Document Present	Flags when the original document is not present in the uploaded file. If a scanned image of a document has been submitted 'Original Document Present' will show as consider. This is expected.
Other	Secondary flag - This will be raised if any other flag occurs under ‘Visual Authenticity’.
Image Integrity	This result indicates that the image uploaded was not of sufficient quality to make a confident fraud assessment of the document.
Conclusive Document Quality	Documents can flag under this section when we have picked up on abnormal document features or obscured data points/security features that hinder our ability to make a confident fraud assessment. This section will flag if the file uploaded: Is a black and white scan Is distorted by liquid scanning* Is distorted by glare, blur or fingers in a photograph If the wet signature is not signed on a passport Is a fraudulent document
Data Comparison	Compares the name and D.O.B. on your client's document against the information submitted on our portal.
Data Consistency	Confirms the data on the MRZ is consistent with corresponding document data. Only performed on Passports and ID documents containing an MRZ.
Data Validation	Validates that the document information appears in the expected format. Typically expired ID documents will fail this check
Police Record	Indicates whether the document has been reported as lost, stolen or compromised on the Amber Hill UK police database.
Compromised Document	Cross-references the document with online sources to ensure the document image is not available on the internet.

Liquid scanning

Some scanners have a feature that aims to improve the clarity of the document they scan by 'smoothing' or distorting pixels. Unfortunately, this impedes the ability to make an accurate fraud assessment of the document. This can also happen if the camera is set to ‘Portrait mode’.
