Rancho Santa Fe does not have home or even curbside mail delivery. Instead we all have centralized PO Boxes in the village post office. However, there is a company that will pick up your mail and deliver it to your house daily Monday through Friday.
RSF Mail Delivery delivers your mail to you every week day. They also pick up outgoing USPS mail, and both UPS and Fedex outgoing packages. This is a very useful service which I've been using for many years. They are highly reliable and convenient.
