TEAS stands for the "Trademark Electronic Application System." There are essentially three paths to applying for federal registration of a trademark:
A TEAS Plus Application is the least expensive option (currently $225.00 per international class). A TEAS Plus application requires submission of a complete application and an agreement that all correspondence with the United States Patent and Trademark Office will be submitted electronically.
A TEAS RF (Reduced Fee) Application also requires that all correspondence be submitted electronically, but does not require submission of a complete application. A TEAS RF Application is more expensive than a TEAS Plus Application (currently $275.00 per international class).
A TEAS Regular Application does not require a complete application, and can be submitted on paper. It is currently the most expensive option for federal registration ($400.00 per international class).
