The United States Postal Service branch in Coronado at 1320 Ynez Place is the only full-service USPS post office serving the 92118 ZIP code on Coronado Island. Carrier delivery routes originating from Ynez Place cover the same residential and commercial addresses served by private-sector shipping providers such as PostalAnnex on the island, and the post office's full-service window handles stamps, Priority Mail, Certified Mail, registered mail, money orders, passport applications, PO Box rentals, and package pickup. The Ynez Place address sits in the southern section of the village near Orange Avenue's resort district, within walking distance of Hotel Del Coronado and the commercial corridor that generates a high volume of outbound business mail and package shipments from the island's retail merchants and commercial offices. Military families at Naval Air Station North Island and Naval Amphibious Base Coronado use the Ynez Place facility for personal mail services, APO/FPO coordination, and the care-package shipping that connects deployed service members to their Coronado Island home addresses. USPS operations parallel the island's private-sector shipping options at Coronado Vehicle Registration Services on B Avenue and other village businesses that handle notary, fax, and document-processing tasks, creating a cluster of transactional services accessible without crossing the Coronado Bridge to mainland San Diego. The 92118 ZIP code covers the entire island — from the Coronado Bridge approach at the north end through the Orange Avenue village to the Silver Strand and Coronado Cays at the south — and all residential and commercial mail routes originate from this single post office. PO Box availability provides a permanent mailing address for residents and businesses on Coronado Beach and throughout the village who prefer a centralized pickup point over carrier delivery.
