# COLOMBIA DIAN

| -------------------- | ------------------------------------------------------------------------------- |
| **Country / Region** | Colombia                                                                        |
| **Document Types**   | Invoice (Factura Electrónica), Credit Note (Nota de Crédito), Documento Soporte |
| **Format**           | XML (UBL 2.1)                                                                   |
| **Standard**         | DIAN 2.1 (Dirección de Impuestos y Aduanas Nacionales)                          |
| **Locale**           | `es_CO`                                                                         |

The Colombian electronic invoicing standard is regulated by the **DIAN** (Dirección de Impuestos y Aduanas Nacionales). It is based on UBL 2.1 with DIAN-specific extensions (`sts:DianExtensions`). DocBits detects Colombia DIAN documents via the DIAN namespace and routes by `CustomizationID`:

| CustomizationID | Document Type                                      |
| --------------- | -------------------------------------------------- |
| 10              | Factura Electrónica de Venta (FACTURA ELECTRONICA) |
| 20              | Nota de Crédito (Credit Note)                      |
| 91              | Nota de Crédito por devolución                     |
| 92              | Nota de Débito                                     |
| DS              | Documento Soporte (DOCUMENTO SOPORTE)              |

The DIAN identifier (**NIT** — Número de Identificación Tributaria) uses `schemeID="31"` in the UBL `CompanyID` element.

## Classification Rules

DocBits detects Colombia DIAN documents by the DIAN namespace string:

| Electronic Document Type     | Pattern                                                                                    |
| ---------------------------- | ------------------------------------------------------------------------------------------ |
| COLOMBIA FACTURA ELECTRONICA | `http://www.dian.gov.co/contratos/facturaelectronica/v1/Structures` + `DianExtensions`     |
| COLOMBIA DOCUMENTO SOPORTE   | `http://www.dian.gov.co/contratos/facturaelectronica/v1/Structures` + `CustomizationID=DS` |

The root element is `<Invoice>` (UBL 2.1) for invoices, `<CreditNote>` for credit notes. All documents include a `<sts:DianExtensions>` block with DIAN authorization data (`InvoiceAuthorization`, `CUFE`/`CUDE` UUID, QR code).

## Querying This Documentation
If you need additional information that is not directly available in this page, you can query the documentation dynamically by asking a question.

Perform an HTTP GET request on the current page URL with the `ask` query parameter, and the optional `goal` query parameter:

```
GET https://docs.docbits.com/administration-and-setup/settings/global-settings/document-types/edi/supported-electronic-documents/colombia-dian.md?ask=<question>&goal=<endgoal>
```

`ask` is the immediate question: it should be specific, self-contained, and written in natural language.
`goal` is optional and describes the broader end goal you are ultimately trying to accomplish on behalf of the user. GitBook uses it to tailor the answer towards what is most useful for that goal.

The response will contain a direct answer to the question and relevant excerpts and sources from the documentation.

Use this mechanism when the answer is not explicitly present in the current page, you need clarification or additional context, or you want to retrieve related documentation sections.
