Businesses that conduct Business-to-Business (B2B) marketing should be aware of the following vulnerabilities specific to their manner of business:

Dual Purpose (Mixed Business & Personal Use) Lines
B2B marketers should be checking their data against state and federal consumer Do Not Call (DNC) lists to reduce the risk of calling or texting dual purpose phone lines.

Business Fax Lines
The Telephone Consumer Protection Act (TCPA) prohibits the use of “any telephone facsimile machine, computer, or other device to send an unsolicited advertisement to a telephone facsimile machine,” which includes business fax lines.

Vicarious Liability
If you use outsourced vendors to make B2B calls or texts on your behalf, you may be held vicariously liable for their potential violations of the TCPA.

Individual Employees vs. the “Business Entity”
Marketing calls that solicit consumers at their place of business rather than the “business entity” itself are not B2B solicitations and would be subject to all normal TCPA and DNC laws.
