4-72 is the commercial name of Servicios Postales Nacionales S.A.S., the official postal operator of Colombia. It provides postal and logistics services across the country and supports the universal postal service, giving individuals, businesses and public institutions access to mail and parcel delivery throughout Colombian cities, municipalities and more remote areas.
For packages within Colombia, 4-72 offers services including Paquetería for parcel and cargo shipments between its covered destinations. Its domestic portfolio also includes certified correspondence and specialized delivery products, while business customers can use additional corporate parcel and logistics solutions according to their shipping requirements.
4-72 also handles international postal traffic to and from Colombia through services such as certified international mail, international parcels and EMS. International shipments can involve foreign postal operators, airlines and customs authorities, so the service available, final delivery procedure and total transit time can depend on the destination country and the postal product selected.
For package tracking, 4Tracking allows you to Track 4-72 packages together with shipments handled by many other postal and courier companies. Enter the shipment number on 4Tracking and let the system detect the carrier when possible, or select 4-72 manually. You can also use the official 4-72 website as a secondary Tracking option by entering the guide number in its shipment-follow-up section.
How 4-72 shipment tracking works
Trackable 4-72 services receive a guide or shipment number that identifies the item as it moves through the postal network. The carrier's official website provides a Sigue tu envío search where customers enter the guide number to consult available shipment information. Certain services also allow customers to retrieve proof of delivery after the shipment has been delivered.
Tracking events depend on the service used. A traceable shipment may receive updates as it is accepted, processed through operational facilities, transported toward its destination and delivered or returned. International packages can also pass through customs and a destination postal operator, which means the time between visible updates can be longer than for a domestic shipment.
How to Track a 4-72 package on 4Tracking
Enter the complete 4-72 guide number in the tracking field on 4Tracking. Automatic carrier detection can identify many shipments, but you can choose 4-72 manually if necessary. Use the number exactly as provided by the sender, merchant or 4-72 receipt, without changing letters or digits to match another shipment format.
4-72 tracking number formats
4-72 does not publish one universal public tracking-number pattern covering every domestic and international service. Different products can use different guide identifiers, so the safest approach is always to use the complete number printed on the shipment documentation.
For certified international mail, 4-72 officially documents a 13-character guide format consisting of two letters, nine digits and two final letters. An example published by the carrier is ET123456789CO. The CO ending identifies Colombia in this international postal-style identifier.
The ET123456789CO example should not be treated as the required format for every 4-72 package. Domestic parcel services and specialized products may use other guide numbers. If your shipment has a different identifier, enter the actual number supplied by 4-72 rather than adding the CO suffix or modifying the number yourself.
Are all international 4-72 items trackable?
No. 4-72 explains that ordinary international mail is not necessarily subject to individual Tracking because this type of mail can be processed collectively. Certified mail, by contrast, receives an individual guide number and can be followed through the available tracking system. If a sender expects end-to-end package tracking, the selected postal service therefore matters.
4-72 delivery times within Colombia
Delivery times vary by service and destination. For its domestic Paquetería service, 4-72 publishes an estimate of 2 business days for urban shipments. Regional and national shipments are listed at approximately 3 to 7 business days, while Trayecto Especial destinations can take up to 10 business days according to the applicable delivery-time matrix.
For example, a parcel sent between locations classified under the urban service is expected within the published 2-business-day timeframe for that product. A shipment classified as regional or national can instead fall within the 3-to-7-business-day range. Deliveries assigned to a special route may require as many as 10 business days.
These are service standards rather than a promise that every package will arrive on a specific date. Destination classification, transportation schedules, operational conditions and unsuccessful delivery attempts can affect the actual delivery date. The latest package tracking event is therefore useful for determining how far the shipment has progressed.
Delivery times for international 4-72 shipments
There is no single reliable total delivery time for every international 4-72 package. The carrier states that international timing can include processing within Colombia, airline transportation, customs procedures and delivery by the postal operator in the destination country.
For applicable international parcel services, 4-72 publishes origin-side time components of about 2 business days for urban origins, 3 to 7 business days for regional or national origins and up to 10 business days for special routes. National Police inspection can add up to 5 business days where applicable. The international flight then depends on the airline, and final delivery depends on the destination postal operator.
Because customs and foreign postal networks are outside 4-72's direct control, those figures should not be added together and treated as a guaranteed international delivery date. For an incoming international package, Tracking can also remain unchanged while the item is between postal networks or undergoing an import process.
Why a 4-72 Tracking status may not update
A gap between scans does not automatically mean the package is lost. A shipment may be traveling between processing locations, waiting for its next operational scan or, in the case of an international item, moving between airlines, customs authorities and postal operators.
If the shipment is ordinary international mail rather than a certified or otherwise traceable service, detailed individual tracking may not be available at all. If you expected a trackable service, confirm the guide number with the sender and check whether the postal product includes shipment tracking.
How to contact 4-72 about shipment problems
If your package is substantially delayed, appears lost, was delivered incorrectly or has another problem, contact 4-72 with the guide number and shipment details. The carrier lists its Contact Center in Bogotá at (+57) (601) 472 2000 and a national customer line at 01 8000 111 210. General customer-service enquiries can also be sent to servicioalcliente@4-72.com.co.
Customers who need to make a formal request, complaint or claim can use the electronic PQR system on the official 4-72 website or submit a request through an authorized 4-72 customer-service office. For international correspondence, the applicable complaint process can differ because exchanges between official postal operators are also governed by international postal rules.
When reporting a shipment issue, provide the full guide number, sender and recipient information and a clear description of the problem. Keep the shipping receipt and any relevant photographs, payment records or delivery information, especially if the request concerns damage, loss or proof of delivery.
Frequently asked questions about 4-72 package tracking issues
Why is my 4-72 tracking number not working?
Check that the entire guide number has been entered correctly and that no letters or digits are missing. A newly accepted package may also need to receive its first processing event before useful Tracking information becomes available. If the number remains unrecognized, confirm it with the sender or contact 4-72.
What does a 4-72 tracking number look like?
There is no single published pattern covering every service. For certified international mail, 4-72 documents a 13-character format made up of two letters, nine digits and two final letters, with ET123456789CO provided as an official example. Other 4-72 products can use different identifiers.
Can I Track ordinary international mail with 4-72?
Not always. 4-72 states that ordinary international mail may be processed without individualized tracking. Certified international mail receives a guide number and is designed to provide shipment traceability.
How long does 4-72 take to deliver a package within Colombia?
For the domestic Paquetería service, the official published times are 2 business days for urban shipments, approximately 3 to 7 business days for regional and national shipments, and up to 10 business days for destinations classified as Trayecto Especial. Other services can have different standards.
Why is my international 4-72 package taking longer than expected?
International delivery involves more than 4-72's domestic network. Airline schedules, inspections, customs processing and the destination country's postal operator can all affect transit time. Continue checking package tracking and contact 4-72 if the shipment appears significantly delayed.
Can I Track 4-72 packages on 4Tracking?
Yes. Enter the shipment's guide number on 4Tracking to follow available package tracking events. Automatic carrier detection can identify many shipments, or you can select 4-72 manually when necessary.
What should I do if my 4-72 package has no new Tracking updates?
Compare the last scan with the normal delivery timeframe for the service and destination. International packages can remain between visible updates while in transit or customs. If the delay extends well beyond the expected timeframe, contact 4-72 with your guide number.
Who should I contact about a lost or damaged 4-72 package?
Contact 4-72 at (+57) (601) 472 2000, use the national line 01 8000 111 210 or email servicioalcliente@4-72.com.co. Formal complaints and claims can also be submitted through the official PQR system. Keep your guide number, receipt and supporting evidence available when reporting the problem.
