Again, I'm playing catch up here, but here's the thing, when a Signature required is on a package that package CANNOT be delivered without a Signature, so someone had to sign for that package. The driver will not be able to release the package without a Signature unless the driver either signed it themselves and left it or manually typed in the number, then changed the 3 digit code that will switch the package from Signature required to release. It's a shady way of doin it. It's like that so a customer can call in if they decide to change the delivery from Signature required to release.
