5. Proof of Address Behavior

Sumsub treats address verification as one PROOF_OF_RESIDENCE step. For this level, there are two possible paths.

Path A

Identity Document Satisfies PoA

When the linked PoA preset allows it, certain identity documents can satisfy proof of address without a separate upload. This is common for identity documents that show a printed residential address, such as some driver’s licenses.

Integration Rule

  1. Upload the identity document first.
  2. Call GET /resources/applicants/{applicantId}/requiredIdDocsStatus.
  3. If PROOF_OF_RESIDENCE is already satisfied, skip the dedicated PoA upload.
Path B

Dedicated PoA Document Upload

If PROOF_OF_RESIDENCE remains unsatisfied after identity upload, upload a separate document using API idDocType: UTILITY_BILL. 

{
  "idDocType": "UTILITY_BILL",
  "country": "DEU"
}

UTILITY_BILL is the API label for the dedicated PoA upload slot. It does not mean only electricity or water bills are accepted. The linked PoA preset determines which real-world document categories pass verification.
