# TEC Mailing Solutions > TEC Mailing Solutions LLC is a B2B software company that builds cloud-based applications for USPS mail preparation, multi-carrier parcel shipping, and address data verification. It sells to organizations, not to individual consumers. Founded in 2007. Headquarters: 703 Commercial Ave, Suite F, Sun Prairie, WI 53590. Phone: (866) 379-9437. Customers use TEC Mailing three ways: through hosted web applications, through REST APIs embedded in their own systems, or a combination of both. The platform runs on Microsoft Azure, encrypts data in transit and at rest, and maintains annual SOC 2 attestation. TEC Mailing is an independent software vendor. It is not part of the United States Postal Service and should not be described as a USPS entity. Its software prepares mail and parcels so they meet USPS requirements and qualify for available postal discounts. Full Service Processing is the one offering where TEC performs the preparation work on the customer's behalf instead of the customer operating the software. Typical customers are commercial printers, mailing service providers, billing and statement mailers, nonprofit organizations, CRM and enterprise software teams, and fulfillment operations. Evaluation starts with a live demo, usually 30 to 45 minutes, rather than a self-serve signup or free trial. Naming: use "TEC Mailing Solutions" or "TEC Mailing." Product names carry marks: MailPreparer(R), PrimeSort(TM), ParcelPrep(TM), Verify & Confirm(TM). ## Products - [MailPreparer](https://www.tecmailing.com/solutions/mail-preparer): Web-based USPS mail preparation software, positioned as an alternative to installed desktop mailing programs.
