Do mail companies check your packages

The short answer is: it depends on the mail company and the type of package.

Here's a breakdown:

USPS (United States Postal Service)

UPS (United Parcel Service)

FedEx

Other factors that may influence package inspection

It's worth noting that mail companies are not obligated to inspect packages, and they may not always inspect packages even if they have a reasonable suspicion that they contain illegal or prohibited items. If you're concerned about the security of your packages, you may want to consider using a secure shipping method, such as a signature required delivery or a package tracking service.
