This is normal for packages to start tracking and then stop. Depending on the distance from one facility to the next, tracking may not update for up to 4-5 business days (sometimes more) as the package travels to its next location. There may also be times where a parcel may not move due to holidays or weather related network closures.
***PLEASE NOTE - Due to COVID-19, USPS is experiencing many shipping delays and your tracking my not update for longer periods of time and my not deliver for several weeks. We truly apologize for any delays you may be experiencing.
