Provide UPS & Fedex access codes to get inside apartment building

[Mike Adams]

We have an apartment building, little 5 story walk-up and we were able to give the USPS an access code to enter the building. Is there a way to provide an access code to UPS and Fedex so they can enter the building and leave packages for the tenants as well? So far, only USPS leaves packages for the tenants, UPS and Fedex just leaves stickies on the main door; which is locked.
