One of two Hillcrest locations under the Annex Brands franchise network operating since 1985, PostalAnnex at 1050 University Ave Suite E107 provides multi-carrier shipping, notary, and mailbox rental in the 92103 ZIP code. Small businesses preparing legal filings can pair notarization here with document preparation at Absolute Executive Legal Document Assistance in the same neighborhood. Each shipment is rate-compared across UPS, FedEx, and USPS at the counter, allowing senders to select by speed, cost, or destination coverage. Hillcrest residents managing tax-season document flow coordinate returns through H&R Block before shipping signed originals from the same storefront. The location handles freight-class shipments for commercial clients relocating inventory or oversized equipment across state lines.
