What HighLevel currently documents
HighLevel’s 2026 messaging guidance says A2P registration is mandatory for domestic application-to-person messaging in the United States, Canada and Puerto Rico. Its SMS compliance settings can append sender identification and opt-out language when those elements are missing.
Build consent into the intake
Do not treat a phone-number field as blanket permission for every future marketing message. The current HighLevel A2P guidance specifically says users cannot be forced to agree to SMS messaging merely to submit a form, survey, quiz, web-chat widget or calendar booking.

Missed-call text-back needs deduplication
HighLevel’s current missed-call documentation warns that the built-in feature can trigger on every missed call, including repeated calls in a short period. For businesses where repeat calling is common, the documentation recommends a workflow approach with waits or filtering to prevent duplicate texts.
