College Postal Plus has operated a San Diego shipping center and personal office on El Cajon Boulevard in College Area since 1986, providing multi-carrier shipping, notary services, live-scan fingerprinting, and copy-center production from a Suite B storefront in the 92115 ZIP. The family-run business holds authorized shipper and drop-off status for USPS, FedEx, UPS, and DHL, processing domestic and international parcels across all four carrier networks from a single counter. Mailbox rental includes a physical street address and round-the-clock access, a format that serves SDSU students, small-business owners, and remote workers who need a permanent address separate from a residential unit. The printing and document center handles the same collateral output as dedicated print shops such as PIP Marketing, Signs, Print nearby in College Area — business cards, flyers, brochures, and large-format copies — bundled with on-site binding, laminating, and faxing. On-site certified notaries handle real estate documents, powers of attorney, affidavits, and other instruments that require a commissioned seal, eliminating the need for a separate notary appointment. Live-scan fingerprinting serves applicants for state licensing boards, background checks, and employment clearances, a service that overlaps with the document-preparation needs at tax and accounting offices such as Pelayo Tax Service on the same El Cajon Boulevard corridor. Custom care-package assembly, passport-photo processing, key duplication, and internet workstations round out the service menu, covering the full range of postal, document, and office tasks under one roof. The El Cajon Boulevard location near SDSU draws a walk-in mix of students shipping textbooks, small-business owners mailing invoices, and residents sending care packages to out-of-state family.
