本技术规范将指定电子商家（任何商业客户发送包裹）和第一物流运营商之间的接口。 界面由两个项目组成: - 物理标签卡在邮件上:内容，大小，最低要求，以保证物流过程的质量和效率（排序，交付）。 - 发送方与物流运营商之间的电子交换与要提供的数据的描述，交换的格式。 虽然万国邮联的指定运营商已经使用专有标准和相关数据组件制定了业务需求，但网上商家已经制定了开放，非营利的最终交付标准，并将其纳入现有的供应链管理环境。 技术规范旨在指定电子商务（任何商业客户发送邮件）与通过并入3个元素组成的第一个物流运营商之间的接口: - 附有邮件物品的物品，具有物品识别信息; - 发件人和物流运营商之间的电子交换关于包裹的调度; - 各种递送链部件所需的数据，特别是最终送达收件人的数据，以便于实现

This Technical Specification will specify the interface between the e-merchant (any commercial customer sending parcels) and the first logistic operator. The interface is composed on two items: - the physical label stuck on the postal item: contents, sizes, minimum requirements to guarantee the quality and efficiency of the logistic process (sorting, delivery). - the electronic exchanges between the sender and the logistic operator with the description of the data to be provided, the format of the exchanges. While designated operators of UPU have drawn up business requirements using proprietary standards and related data components, online merchants have developed open, not-for-profit standards for final delivery which are integrated into their existing supply chain management environment. The Technical Specification aims to specify the interface between the e-merchant (any commercial customer sending postal items) and the first logistic operator composed by incorporating the 3 elements: - physical label attached to the postal item with information for item identification; - electronic exchanges between the sender and the logistic operator concerning parcels dispatch; - data needed for various delivery chain parts, in particular final delivery to the recipient, in order to facilitate exchange between the item-specific identifiers. NOTE 1 The last element enables the growth of integrated, data-driven systems which support highly efficient and customer-driven cross-border ecommerce. This reflects the current trend to B-to-B-to-C delivery solutions in the European and international cross border e-commerce markets. Delivery from original source to final consumer can be split over more than one service provider. NOTE 2 C-to-B-to-B-to-C solutions will be an extension, in particular when returns are specified. The “first C” would indicate that consumers wishing to return items, or induct items themselves, will be able to print labels following the fundamentals specified in this standard. E-merchant exchange data with logistic operators (i.e. the postal operators, but not limited to those designated to fulfill the rights and obligations of UPU member countries) to help, simplify and enable the consequential logistic and transactional tasks. The establishment of common definitions and electronic formats, safeguards the reliability and decreases the overall costs by avoiding software development costs, multiple printing equipment, over-labelling during the process, and the manual sorting.
