Can I text B2B leads without an opt-in?

Treat the answer as no. The TCPA protects mobile numbers, and it does not carve out business-to-business messages: a work cell is still a cell. Some B2B scenarios sit in grey areas courts have read differently, but building a program on a grey area means betting the program on litigation you do not control. Know your consent basis for every contact before you send.

The common misreading is that the TCPA is a consumer statute, so B2B is exempt. The statute regulates calls and texts to mobile numbers, whoever pays the phone bill, and plaintiffs' firms have spent years testing exactly this theory against B2B senders.

There are legitimate consent bases short of a web form: an existing business relationship with documented number exchange, a direct request to be texted, a booked meeting the text confirms. What none of them cover is a purchased list of strangers, which is its own question with its own answer.

Whatever the consent basis, the operational floor is identical: honor opt-outs fast, keep records, respect quiet hours. The full operating checklist is in the TCPA compliance guide. Not legal advice; run it past counsel.
