Qualified Electronic Signature (QES) Verification
Effortless and compliant customer onboarding for the entire Europe.
Sumsub's QES Verification is a Qualified Electronic Signature-based remote onboarding and document signing solution that meets the highest identification standards in the European region. It is recognized as a compliant method for customer verification under the national AML/CDD requirements in all 30 member states of the European Economic Area (EEA). Moreover, the solution facilitates instant high-value and high-risk document signing with the legal power of a handwritten signature that is formally accepted on an international level.
Since QES Verification is consistent with the electronic trust service requirements established under the eIDAS framework which has been incorporated into national AML/CDD law by EEA countries, businesses are not required to individually comply with jurisdiction-specific identification standards, including those of BaFin in Germany, ANSSI in France, SEPBLAC in Spain, or ADR in Romania.
The solution works by combining Sumsub's certified Identity Verification modules together with the Document Signing service enabled by a Qualified Trust Service Provider (QTSP). To complete the onboarding journey using a QES, the customer simply needs to verify their identity and seamlessly sign the relevant documents using a One-time Password.
Overall, QES Verification is an excellent choice for user verification and electronic document signing that not only helps organizations achieve regulatory compliance on a pan-European basis, but also enables a fast and effortless experience for their end customers.
Note
Under the requirements of the German Money Laundering Act (GwG § 12 (1) 3.), when a person's identity is verified by means of a qualified electronic signature, the obliged entity is also required to ensure that a transaction is executed directly from a payment account, which is held in the name of the verified individual.
In order to help regulated organizations in Germany achieve compliance with this requirement, Sumsub has simultaneously enabled the Penny Drop Verification solution, which enables combining Identity Verification, Payment Initiation, and Qualified Signing in a single user journey.

Supported jurisdictions
Sumsub's QES Verification solution supports all jurisdictions that have incorporated the eIDAS framework (Regulation (EU) No 910/2014) and, specifically, the regulatory guidelines concerning Qualified Electronic Signatures as part of their national AML/CTF laws for customer identification and document signing. That includes all 30 member states of the European Economic Area (EEA) as well as the United Kingdom and Ukraine.
Note
Countries in the European region, such as Georgia, Serbia, Switzerland, and Turkey, have separate approval processes for Qualified Trust Service Providers under their national laws that should be executed in order to offer Qualified Signing locally. For the time being, Qualified Electronic Signatures issued under the eIDAS technical standards and legal framework are not recognized on a formal basis in these jurisdictions.
Supported identity documents
Sumsub's QES Verification supports all official identity documents that are recognized for remote customer verification under the eIDAS framework and ETSI technical standards. Depending on the jurisdiction, these may include National Identity Cards, Passports, Driving Licenses, and Residence Permits. Overall, the solution offers around 98% adult population coverage in each applicable country. Explore our Coverage Sheet for a full breakdown of the supported identity documents.
Note
While a number of countries have not incorporated the eIDAS regulatory guidelines into their AML/CTF laws and do not recognize Qualified Electronic Signatures as defined under the framework, the ETSI technical standards still accept the identity documents of those countries for customer verification and Qualified Signature issuing purposes. As a result, the provided list of supported identity documents covers a much broader scope than the list of supported jurisdictions.
Supported languages
The QES Verification solution currently supports the following languages:
- English
- German
- French
- Italian
- Spanish
- Dutch
- Polish
Note

- Contact your Customer Success Manager if you wish to include an additional language to the onboarding flow. The expected delivery time is ~1 month.
Compliance overview
Sumsub’s Qualified Electronic Signature ensures several crucial elements, which gives it the same legal power of a handwritten signature:
- Integrity — no modifications to the document or its content can be made once the signature has been issued;
- Authenticity — the signature is based on a qualified certificate, which serves as a proof of the signer’s identity;
- Non-repudiation — the signer cannot deny having completed the signing process himself.
For these reasons, QES Verification adheres to the highest identification standards under the eIDAS framework (Regulation (EU) No 910/2014), which outlines the use of electronic identification and trust services and is considered equivalent to in-person customer onboarding. As a result, the solution is recognized as a compliant identification method by national AML/CTF regulatory requirements in all 30 member states of the European Economic Area (EEA) as well as United Kingdom and Ukraine.

Is the customer allowed to leave the QES Verification session while their identity data is being processed and resume it later?
Yes, once the the end-user's identification status changes, Sumsub will immediately send the client an API webhook informing them about it. In turn, this will allow them to send an in-app or email notification to the end user, letting them know that their data has been processed and they can continue with the final steps of the QES Verification.

There are no limits to the number of documents that can be uploaded for signing in a single session. However, the maximum size of the total uploads is 30MB.

What is the average time of the document signing step of the QES Verification?
Document signing with a Qualified Signature is expected to take an average of 5 seconds. The required time additionally depends on these factors:
- Number of documents uploaded for signing;
- Size of the uploaded documents;
- Number of signatures required in each document;
- Latency of the SMS OTP code delivery.
Does Sumsub charge additionally depending on the number of signed documents or signatures per document?
No, the number of signed documents or required signatures per document does not affect the solution billing.
Does Sumsub charge its clients per initiated or per successfully completed signing sessions?
The charges apply per each initiated signing session, but only after the customer successfully passes the Identity Verification part of the process. Moreover, if the customer leaves the signing session before completing it, the same session, which is valid for 60 minutes, can be re-used, avoiding additional charges.
