What Is the Postal Code of Colombia?
A Colombia postal code is a 6-digit numeric code that identifies specific geographic delivery areas across the country. The format follows XXYYZZ, where the first two digits represent the department, the next two indicate the postal zone (with "00" reserved for department capitals), and the final two pinpoint up to 100 postal districts within that zone. Since 2009, this system has enabled more precise mail routing and logistics nationwide.
How the Colombian Postal Code System Works
The 6-digit structure was standardized by DANE (Departamento Administrativo Nacional de Estadística) and operates through a hierarchical encoding method. Each component serves a distinct logistical purpose in Colombia's national mail infrastructure.
- First 2 digits (XX): Encode the department-one of Colombia's 32 administrative divisions plus Bogotá D.C.
- Next 2 digits (YY): Define postal zones (00-89), where "00" marks the department capital; codes 90-99 have special meanings
- Last 2 digits (ZZ): Identify up to 100 postal districts per zone, enabling neighborhood-level precision
This design theoretically supports 288,000 unique postal districts nationwide (32 departments x 90 zones x 100 districts). The system covers all 1,123 municipalities across Colombia's 33 territorial entities.
Key Departmental Codes at a Glance
| Department | Prefix (XX) | Capital City | Example Code |
|---|---|---|---|
| Bogotá D.C. | 11 | Bogotá | 110231 |
| Antioquia | 05 | Medellín | 050001 |
| Valle del Cauca | 76 | Cali | 760001 |
| Cundinamarca | 25 | Bogotá (excl. D.C.) | 250001 |
| Atlántico | 08 | Barranquilla | 080001 |
| Bolívar | 13 | Cartagena | 130001 |
| Nariño | 52 | Pasto | 520001 |
| Magdalena | 47 | Santa Marta | 470001 |
Historical Development and Implementation
Colombia's postal code system was officially implemented in 2009, representing a modernization effort by 4-72 (the national postal operator) to align with international logistics standards. Before this date, mail delivery relied primarily on descriptive addresses without standardized numeric coding, causing delays in rural areas.
As noted by postal experts, "postcodes were only recently implemented throughout Colombia, which is why they are not yet widely used or well-known among older generations". Despite this, adoption has grown steadily, with over 22,849 verified postal code entries in national databases as of early 2024.
- 2009: DANE launches 6-digit system nationwide
- 2012-2015: Gradual integration with private courier services (Servientrega, Interrapidísimo)
- 2018: 4-72 deploys online lookup tool at www.4-72.com.co
- 2024: Database expands to 22,849 verified codes covering 98% of urban areas
Why Colombian Postal Codes Matter Today
The precision of 6-digit coding enables GPS-based delivery routing, e-commerce logistics, and emergency services localization. In Bogotá alone, the system distinguishes between 1,200+ neighborhoods using codes like 110111 (La Candelaria) versus 110311 (Chapinero).
For international senders, using the correct Colombian ZIP code reduces delivery time by 2-3 days on average. Without it, mail may be misrouted through regional sorting centers, adding up to 72 hours of transit delays.
"The postal code is essential for complementing a specific address and distinguishing it from neighboring areas with similar names. This allows more exact identification on maps and accelerates postal and GPS location processes."

How to Find Any Colombian Postal Code
Locating a specific postal code is straightforward through official and third-party resources:
- Official 4-72 Lookup: Visit www.4-72.com.co and use the ZIP code search tool by city/street name
- Departmental Selection: Choose department → city → neighborhood to receive the exact code
- Mobile Apps: "Código Postal Colombiano" apps exist on Android/iOS with offline map integration
- Rural Areas: Some remote municipalities use 5-digit variants or expanded 9-digit block codes (not mapped in OSM)
FAQ Section
Special Cases and Expanded Codes
Beyond the standard 6-digit format, Colombia employs specialized variants for specific use cases:
- 5-digit municipal codes: Used at municipality level for broad regional routing
- 9-digit block codes: Expanded codes identifying specific city blocks (not used in OpenStreetMap)
- Special zones 90-99: Reserved for military, diplomatic, or high-security facilities
The Amazonas department (prefix 91) exemplifies challenges in remote areas, where delivery points may span hundreds of square kilometers with minimal infrastructure.
Geographic Coverage and Statistics
As of May 2026, the system demonstrates robust national penetration with the following metrics:
| Metric | Value | 数据来源 |
|---|---|---|
| Total departments covered | 33 (32 + Bogotá D.C.) | |
| Municipalities served | 1,123 | |
| Verified postal codes in database | 22,849 | |
| Theoretical maximum districts | 288,000 | |
| Urban area coverage | 98% | |
| Average delivery time with code | 2-3 days faster |
Common Mistakes to Avoid
When using Colombian postal codes, avoid these frequent errors that cause delivery failures:
- Adding letters: Colombian codes are purely numeric-no alphabetic characters exist
- Using 5 digits only: Always provide all 6 digits; truncation causes routing ambiguities
- Mixing Bogotá D.C. with Cundinamarca: They use different prefixes (11 vs. 25) despite shared geography
- Assuming universal adoption: Rural addresses may still rely on descriptive landmarks rather than codes
The Future of Postal Coding in Colombia
Colombia's postal infrastructure continues evolving toward smart logistics integration. Plans include AI-powered address validation, real-time code updates via mobile apps, and expansion of 9-digit block coding for micro-delivery zones in major cities.
With e-commerce growing at 23% annually in Colombia, accurate ZIP code usage remains critical for maintaining delivery efficiency. The 4-72 operator reports that 87% of在线 shipments now include verified postal codes-up from 42% in 2018.
