DNP (Sisbén IV and RUI)

The Departamento Nacional de Planeación (DNP) runs Sisbén IV, the survey that classifies Colombian households from A1 (extreme poverty) to D21 for social programmes, and the Registro Universal de Ingresos (RUI), the income-based classification that succeeds it. Both sit on the Registro Social de Hogares, the DNP’s register of more than 55 million people. Send a document and get both classifications, or find the Sisbén office that serves a municipality. POST /co/dnp/social-classification/v1 Returns a person’s Sisbén IV group and RUI classification.

Field	Type	Notes
`document_type`	enum	Colombian document type (`CC`, `TI`, `CE`, `RC`, `PA`, `PEP`, `PPT`). Default `CC`.
`document_number`	string	Required. 3-30 chars.

Field	Notes
`found`	`true` when the person has a Sisbén IV group, a RUI classification, or both. `false` is a normal `200`, not a `404`; `sisben` and `rui` are then `null`.
`sisben`	`{ group, category, label, municipality, department }`, or `null`. `group` runs from `A1` to `D21`; `label` is the register’s own wording, e.g. `Vulnerable`; `municipality` and `department` are where the person was surveyed.
`rui`	`{ classification, category, income_group, full_name, sex, age, municipality, department }`, or `null` when the person has no RUI classification.

category is the letter both classifications share:

`category`	Meaning
`A`	Extreme poverty
`B`	Moderate poverty
`C`	Vulnerable
`D`	Neither poor nor vulnerable

The RUI (Registro Universal de Ingresos) classifies people by estimated income and succeeds Sisbén IV as the targeting instrument for social programmes from the second half of 2026 (Decreto 875 de 2024). A person can have one without the other, so read both.
