SMS consent is a record your system should be able to explain.

What a useful consent record can capture

• Phone number
• Consent status
• Date and time captured
• Source or form where consent was obtained
• The disclosure language presented at that time
• The sender / brand covered
• The message category or campaign scope
• History of opt-in and opt-out events

Industry guidance

CTIA’s current Messaging Principles & Best Practices says non-consumer senders are expected to obtain consumer consent generally, obtain express written consent for marketing messages, and ensure consumers can revoke consent. CTIA also emphasizes that opt-in is tied to the specific sender and campaign context rather than being a generic asset to trade.

Do not build marketing lists from ambiguity

A phone number collected for one operational reason does not automatically answer whether promotional texting is appropriate. Keep the permission path explicit and keep the record with the contact.
