The Sistema de Seguimiento de Solicitudes allows you to create and track two types of transparency requests: DAI (Derecho de Acceso a la Información) and ARCO (Acceso, Rectificación, Cancelación y Oposición). This guide walks you through the complete process.

​
Understanding Request Types

​
DAI (Derecho de Acceso a la Información)

Requests for access to public information:
  • Response deadline: 10 business days
  • With extension: 20 business days
  • Used for general information requests

​
ARCO (Datos Personales)

Requests related to personal data rights:
  • Response deadline: 20 business days
  • With extension: 40 business days
  • Includes: Access, Rectification, Cancellation, Opposition
  • Requires specifying which ARCO right is being exercised

​

  • Folio: Request reference number (e.g., “00001/2026”)
  • Nombre: Name of the person making the request
  • Tipo de Solicitud: Select “DAI” or “ARCO”

5

  • Electrónico PNT: Through the national transparency platform
  • Correo: Via email
  • Otro: Other method
  • No aplica: Not applicable
6

Save the Request

Click Guardar to create the request. The system will automatically:
  • Calculate the response deadline (10 or 20 business days)
  • Skip weekends and holidays (días inhábiles)
  • Set initial status to “En proceso”

​
Understanding Request Stages

Requests progress through three main stages, visually represented in the interface:

Etapa Inicial

Initial intake and processing of the request

Etapa de Seguimiento

Follow-up, prevention periods, and extensions

Etapa Final

Final response and request closure

​
Managing Request Details

Once created, you can access detailed request information from the Índice de Expedientes page.

​
Editable Fields

When viewing request details (Detalles de Expediente), you can update:

​
Status Management

  • Estatus: Change between “En proceso” and “Terminada”
  • Fecha de Respuesta: Record when the response was provided

​
Prevention (Prevención)

If additional information is needed from the requester:
  1. Set Prevención to “Si”
  2. System calculates Fecha Límite para Prevención (10 business days)
  3. If requester provides information: Set Subsana Prevención to “Si”
  4. If “Si”: Request timer restarts from subsanation date

​
Extension (Ampliación)

For complex requests requiring more time:
  1. Set Ampliación to “Si”
  2. System automatically doubles the response deadline:
    • DAI: 10 → 20 business days
    • ARCO: 20 → 40 business days
  3. Response deadline updates automatically

​
Automatic Deadline Calculation

The system intelligently calculates deadlines by:
Excluding Saturdays and Sundays
Skipping official holidays (días festivos)
Accounting for custom non-working days
Updating automatically when request type or extension changes

​
Example: Creating a DAI Request

Here’s a practical example: 
Folio: 00123/2026
Nombre: María González López
Tipo de Solicitud: DAI
Fecha de Inicio: 2026-03-10 (Monday)

System automatically calculates:
→ Fecha Límite de Respuesta: 2026-03-24 (10 business days later)

If Ampliación = "Si":
→ New Fecha Límite: 2026-04-07 (20 business days total)

​
Request Status Options

The system tracks requests through these status values:
StatusMeaningWhen to Use
INICIOInitialRequest just created
PROCESOIn processActively being worked on
EN PREVENCIÓNIn preventionAwaiting additional info from requester
EN AMPLIACIÓNExtendedExtension period granted
TERMINADACompletedResponse provided
DESECHADADismissedRequest dismissed (no subsanation)
CANCELADACancelledRequest cancelled
Use filters in the Historial de Solicitudes page to quickly find requests by status, date, or folio number.

​
Best Practices

Use a consistent folio format (e.g., sequential numbers with year) to make requests easy to track and reference.
Always fill in the requester’s name and preferred response method to ensure proper communication.
Update request status regularly to maintain accurate records and avoid missed deadlines.
When setting prevention, document what information was requested and when it was received.
