About OSM Worldwide

OSM, or One-stop mailing, is a courier partner in the US region to provide quick, affordable deliveries. The company is an approved USPS partner offering special postal service discounts. Through their services, the company offers a hybrid service that blends the national coverage of their supply chain with the last mile delivery efficiency of the USPS to provide a seamless experience to their clients and customers. 

OSM was initially founded in 2003 as a shipping broker for the various delivery services in the country. The company grew to a national level with seamless deliveries and excellent customer support. As it started international deliveries in partnership with the local postal services of the respective countries, it was rebranded as OSM Worldwide. The courier partner uses USPS to handle last-mile deliveries to provide the customers with a faster and quicker delivery experience.

For ecommerce businesses who pride themselves on quicker deliveries, the company does provide expedited shipping services. The widespread supply chain and specialized partners of OSM worldwide allow them to guarantee a 1-5 day delivery within the United States. The company does deliver six days a week, so your customers do not have to wait for business days to receive their orders. Other than that, the company handles shipping requirements for specific industries, including clothing, apparel, and hazardous materials. 

The OSM worldwide services have thrived in the cut-throat world of logistics because they adapt to the changing economy. The company provides special services that cater to the need of the rapidly growing ecommerce sector. The company's OSMART tracking service lets you track your order from your door to the customer's door in real-time. It provides other services like right-size packaging, subscription fulfillment, and pickup schedule to make it easier for ecommerce businesses and vendors to fulfill their orders. ClickPost has a carrier integration with OSM worldwide to cater to the company's needs and primarily delivers within the US region.

FAQs about OSM Worldwide


1) What is USPS via OSM?

OSM is an approved USPS partner. The carrier uses the postal service services to cover their last-mile deliveries more efficiently. However, it has its supply chain to get a parcel or a shipment across the country in a much more efficient way. That is why the carrier can guarantee the delivery within 1-5 days. 


2) How reliable is the OSM tracking service?

OSM provides a tracking service to their customer, like most carriers, through a tracking page wherein you can put your order id to track your shipment. Alternatively, it also provides an OSMART tracking service that enables customers and merchants to track their orders from door to door in real-time.
