WHO Digital Documentation of COVID-19 Certificates (DDCC)
1.0.1 - release
This page is part of the WHO Digital Documentation of COVID-19 Certificates (DDCC) (v1.0.1: releases Draft) based on FHIR (HL7® FHIR® Standard) R4. This is the current published version. For a full list of available versions, see the Directory of published versions
Functional requirements are documented in the Digital Documentation of COVID-19 Certificates (DDCC): Vaccination Status (DDCC:VS) and the DDCC: Test Result (DDCC:TR) - Technical Specifications and Implementation Guidance.
The high-level functional requirements are written as guidance requirements only to be used as a starting point for Member States or other interested parties that need to develop their own specifications for a digital solution for DDCC to take and adapt.
The following includes functional requirements for DDCC:VS and DDCC:TR, along with mappings to use cases, as well as related requirements.
The DDCC guidance uses specific terminology in requirements. The definitions are based on the definitions published by the Internet Engineering Task Force (IETF) https://www.ietf.org/rfc/rfc2119.txt.
MAY is used to describe technical features and functions that are optional, and it is the implementer’s decision on whether to include that feature or function based on the implementation context.
SHALL is used to describe technical features and functions that are mandatory for this specification.
SHOULD is used to describe technical features and functions that are recommended, but they are not mandatory. It is the implementer’s decision on whether to include that feature or function based on the implementation context. However, the implementer is highly recommended to review the reasons for not following the recommendations before deviating from the technical specifications outlined.
As the Test Result guidance does not include the Continuity of Care scenario, there are fewer related requirements for the DDCC:VS Continuity of Care scenario.

|---|---|---|---|---|---|---|
| DDCCVS.FXNREQ.037 | Paper cards and the validation markings they bear SHOULD be designed to combat fraud and misuse.

| DDCCVS.FXNREQ.047 | A PHA servicing a validation request MAY respond with basic details of the vaccination card holder (name, date of birth, sex, etc.), in accordance with PHA policies, so the Verifier can confirm that the vaccination card corresponds to the DDCC:VS Holder who has presented himself or herself for validation. | x | x | DDCCTR.FXNREQ.031 | ||
| DDCCVS.FXNREQ.048 | A PHA SHALL maintain a PKI to underpin the signing and verification process. Lists of valid public keys and revocation lists will be held in such a system and be linked to the DDCC:VS Generation Service to associate public keys with HCIDs. | x | x | DDCCTR.FXNREQ.032 | ||
| DDCCVS.FXNREQ.049 | A PHA MAY log the requests it receives for verification (even if rendered anonymous), so that it has a searchable history for the purposes of audit and fighting fraud, provided that such logging respects data protection principles. | x | x | DDCCTR.FXNREQ.033 | ||

| DDCCVS.FXNREQ.053 | A PHA SHOULD be able to validate that the requestor making a verification request is an authorized agent, but MAY also allow anonymous verification requests. | x | x | DDCCTR.FXNREQ.037 | ||
| DDCCVS.FXNREQ.054 | The certificate authority (or authorities) in each country SHALL maintain records of the DSCs issued for the purpose of signing vaccination certificates and expose any service(s) that allow a public key to be looked up and checked against its records to check for validity. | x | x | DDCCTR.FXNREQ.038 | ||
| DDCCVS.FXNREQ.055 | Any communication between a Verifier and a DDCC:VS Registry Service or other data service managed by a PHA SHALL be secured to prevent interference with the data in transit and at rest. | x | x | DDCCTR.FXNREQ.039 | ||
| DDCCVS.FXNREQ.056 | SMS-based verification of alphanumeric HCIDs MAY be provided by a PHA as a means of sending a verification request or receiving a response with a status code. | x | DDCCTR.FXNREQ.040 | |||
| DDCCVS.FXNREQ.057 | If a verification request is made in country A for a certificate that was issued by country B or a supranational entity, then country A’s PHA SHOULD have a means of transferring the request/ querying the data held by that authority. | x | DDCCTR.FXNREQ.041 | |||
| DDCCVS.FXNREQ.058 | A Member State SHOULD put in place bilateral or multilateral agreements with other countries or with a supranational entity or regional body for access to those entities’ vaccination certificate data and digital signatures. | x | DDCCTR.FXNREQ.042 | |||
| DDCCVS.FXNREQ.059 | Communications between one country’s and another’s PHA or a supranational DDCC:VS Registry Service SHALL be secure and prevent interference with the data in transit and at rest. | x | DDCCTR.FXNREQ.044 | |||
| DDCCVS.FXNREQ.060 | It SHALL be the ultimate responsibility of the country where verification is taking place to decide whether a vaccination claim is valid or not. | x | DDCCTR.FXNREQ.045 | |||

Processes for specimen collection, data collection, sample analysis and the generation of test reports (if required) will be defined by Member States, are outside the scope of the DDCC:TR guidance, and are preconditions for generating a test result certificate. Member States will need to define how a certificate will be generated, issued and adapted to their own contexts and levels of digital maturity, in compliance with their legal and policy frameworks. Due to these preconditions and differences, mappings to use cases are not included for DDCC:TR certificate generation.
