FedEx- and UPS-authorized PostalAnnex Service Center #0050 in Point Loma anchors the Shelter Island commercial strip with DOJ-certified Live Scan fingerprinting, multi-carrier shipping, and California-commissioned notary services. Marina tenants and chandleries along the Shelter Island basin rely on the center's custom crating for oversized marine hardware—the same vessel electronics that Seanet Electronics Inc installs on sport fishers and cruisers docked nearby. Multi-carrier rate comparison across UPS, FedEx, DHL, and USPS lets shippers weigh transit time against cost on a single counter, while private mailbox rental assigns a real Shelter Island Drive street address for sole proprietors who need a commercial mailing presence. Expedited passport processing in two-, four-, or seven-to-ten-day tiers covers last-minute international travel, and on-site passport photography meets current State Department sizing and background standards. Mobile notary deployment reaches closings and contract signings across the Point Loma peninsula, a service frequently paired with the real-estate and litigation paperwork handled at Law Office of Daniel S Castaneda, APC. The center's Navis Pack & Ship freight partnership handles crated artwork, antique furniture, and industrial equipment that exceed standard parcel dimensions and weight limits.
