If you have a paper form that includes a phone number field, you can allow customers to opt into future text messages, as long as it has a check box and a description of what they're signing up for.
Paper Form Compliance
For the opt in on your paper form to be compliant, it needs to have a checkbox and a disclaimer that the person filling out the form agrees to receive your text messages.
