Caller service is a sister service to post office box
service as provided by the United States Postal Service
, specifically for the purpose of receiving large volumes of daily mail
that would otherwise not fit into a PO box, or if there is a need to receive mail multiple times per day.
Subscribers to this service are assigned a PO box address, which is used for the caller service; mail is sorted and placed into any number of containers or mail sacks as required to handle the load, and the subscriber in turn retrieves the mail from their post office.
This service is otherwise identical to post office box service, except you no longer require a key, and you cannot retrieve your mail after hours at all.
Cost for this at the time fo this write up is $412 per six months per address, plus $32 per year for each caller number.
