What AccuZIP does

AccuZIP, Inc. is a US-based postal software company founded in 1992 and led by founder/owner/CEO Steve Belmonte from its headquarters in Atascadero, California (with a smaller site noted in League City in firmographics). The company builds and sells AccuZIP6, a Windows/.NET-based desktop postal software platform certified by the USPS for CASS address standardization, PAVE GOLD presorting, and NCOALink change-of-address processing, and it supplements this with the AccuTrace mail-tracking service using Intelligent Mail barcodes and QR codes, the ANKLink 48-month move-update module, AccuGeocoder, an ACS automated address-correction module, and a recently launched suite of RESTful APIs (Direct Mail API, CASS API, AccuTrace API) and a COM Object Developer Toolkit for embedding CASS-certified validation into third-party applications. Its technology stack integrates USPS reference data (NCOALink ~160M records, PAVE presort logic, MAC Batch), Maponics ZIP+4 centroids, and Canada Post PoCAD, and operates in-house under HIPAA, HITECH, and SOC 2 Type I attestations.

The platform is delivered through five software editions (Standard, Business, Full-Service, Professional, Periodicals) plus a free Print-Only Edition, with add-on modules billed annually (e.g., NCOALink standalone $795/year, Monthly CASS updates $399/year), usage-based mail tracking ($155–$625/month by volume), per-record data enhancement services (~$1.00/1,000 records with volume discounts), AccuTag tray-tag hardware, and professional services for Informed Delivery and API integration. AccuZIP sells through direct phone-based consultative sales with a free live demo, pay-per-use for occasional mailers, and a partner channel via web-to-print platforms (EFI Digital StoreFront, Enfocus Switch, XMPie uStore, DirectSmile, DirectMail2.com, PrintNow, SK+G) and Salesforce AppExchange.

The customer base spans enterprise, mid-market, and SMB across insurance, financial services, healthcare, real estate, printing, retail, nonprofit, and political verticals, with named users including Allstate, Mayo Clinic, Wells Fargo, IBM, Procter & Gamble, Century 21, RE/MAX, UPS Store, Shutterfly, AAA, American Cancer Society, and Salvation Army. Distribution is concentrated in North America. AccuZIP is privately held, has not raised outside funding, and reports 11–50 employees; the firm is recognized in the Smithsonian National Postal Museum and holds an A+ BBB rating.
