Accuracy and currency
US A2P rules, registry fees, carrier throughput, and regulatory deadlines change frequently and without notice. We work from primary sources and date every reference, but figures here may be out of date or incomplete by the time you read them. We make no representation or warranty about the accuracy, completeness, or currency of any content. Always confirm against the official US government resources, The Campaign Registry, and your CSP or carrier before relying on anything.
No guaranteed outcomes
Nothing on the Site guarantees that your brand will be approved, that your messages will be delivered, that your calls will be answered, or that you will be compliant with the TCPA, CTIA guidelines, FCC rules, or carrier policies. Compliance is fact-specific and depends on your own circumstances and conduct.
Tools are estimates
The calculators, generators, validators, and checklists are aids for planning and education only. Their outputs are estimates and starting templates, not authoritative determinations, legal documents, or quotes. Verify every figure and have any consent language, privacy clause, or policy reviewed by counsel before use.
