As part of the new Companies House verification requirements, verification of directors and PSCs must include validating the cryptographic features of the identity document. This is able to be done in Firmcheck with our new Cryptographic ID check.
‼️ Cryptographic checks can only be used to validate passports, both domestic and international. A full list of supported countries is available here.
Collect Passport Details
Either issue an Advanced ID Check to your client, or
Upload their passport under Proof of Identity.
This step captures the key passport fields required: passport number, full name, and date of birth.
Request the Check
Click Cryptographic ID Check.
Enter the client’s unique email address.
Client Email Instructions
The client will receive an email with instructions to download the Firmcheck app.
The check must be completed on their mobile phone.
If they open the email on a desktop, they should simply forward the email to their phone, the link will still work.
Completing the Check
In the app, the client follows on-screen prompts.
They will be asked to hold their passport against the back of their phone so the chip can be read.
The app will guide them if adjustments are needed.
Once the process is complete, the result will be returned to Firmcheck as a green tick, confirming the passport has been successfully verified.
Cryptographic checks are included on compliance plan subscriptions, and £4 per check on ID checker plans.
