Standards and assignment boundary

Use the exact symbology required by the receiving system. WebToolArc can validate supported syntax and check digits, but it does not allocate GS1 identifiers, certify regulated documents, or guarantee acceptance by a particular scanner, retailer, carrier, or institution.

SMS payload semantics

The QR stores a phone number and message request. Dialing and message behavior vary by device and app, so confirm the destination number before distributing the code.
