Usually, once a package is picked up by a courier, it means that it has entered the logistics system and has begun to be delivered according to the established route. At this stage, it is difficult to adjust the package because it is already in the process of transportation. The specific feasibility will depend on many factors, such as the regulations of the logistics company, the specific stage of delivery, and the specific content of the adjustment.

If you need to make adjustments after the package is picked up, it is recommended to contact the seller or the e-commerce platform customer service as soon as possible to find out if there is still a possibility of modification or adjustment. At the same time, you can also contact the courier directly to understand the current status of the package and whether certain adjustments are possible. However, it should be noted that due to the complexity and timeliness of the logistics system, many adjustments may not be possible, or require additional costs and time.

In order to avoid similar situations, it is recommended to carefully check the order information before the package is picked up to ensure that all information is accurate. This will not only reduce unnecessary troubles in the future, but also ensure that the package can be delivered to the destination on time and safely.

In summary, it is unlikely that Temu will adjust the package after the courier picks it up, but the specific situation still needs to be communicated and confirmed with the seller, e-commerce platform customer service or courier company.
