The sentence "we are B2B so DNC does not apply to us" is doing a lot of work in this industry, and it is only half true even where it is true at all. It addresses one register, and the register is not where the money in a claim comes from.
| Rule | Applies to a business mobile? | What it turns on |
|---|---|---|
| National DNC Registry | Generally no | Residential subscriber, business-purpose call |
| TCPA autodialler / prerecorded rules | Yes | The number being wireless, not who answers |
| Internal do-not-call list | Yes | Anyone who asks you to stop |
| State mini-TCPA laws | Often yes | The state, and how it defines the equipment |
| Calling-hour restrictions | Often yes | State law, by the called party’s time zone |
The internal list is not optional
Whatever the registry says, a company making telephone solicitations has to maintain its own do-not-call list and honour requests on it. This one has no B2B carve-out worth relying on and it is the one most floors handle worst — a rep marks a lead "not interested" in the CRM and nothing propagates to the dialler, the SMS tool or the email platform.
Sole proprietors are the awkward case
A large share of small-business owners use a personal mobile as the business line. That number can be simultaneously a business contact and a residential subscriber’s phone, and the case law does not give you a clean rule. The practical answer is not to litigate the category — it is to have consent that would hold either way, which is exactly what a named, timestamped, affirmative disclosure gives you.
It is also a reason the qualification floor matters commercially as well as legally. Leads screened to businesses over $30,000 a month in revenue contain far fewer of these edge cases than leads that let self-employed operators through, which is one of several reasons we write the ad creative to repel that segment.
Questions brokers ask
Does the National Do Not Call Registry apply to B2B calls?
Generally not. The registry protects residential subscribers, and a call to a genuine business line for a business purpose sits outside it. That is a narrower exemption than it sounds, because it does not touch the TCPA rules on automated calls and texts to wireless numbers.
Is calling a business owner’s mobile covered by the TCPA?
The restrictions on automated calls and prerecorded messages to wireless numbers turn on the number being wireless, not on who answers or why. Most merchant numbers on a funding application are mobiles, so the safe operating assumption is that they are covered.
Do I need an internal do-not-call list for B2B?
Yes. A company making telephone solicitations has to maintain one and honour requests on it, and this obligation does not have a business-to-business carve-out worth relying on. It is also the one most floors implement badly.
What about a sole proprietor using a personal phone?
That number can be both a business contact and a residential subscriber’s phone, and the case law gives no clean rule. Rather than argue the category, hold consent that would be valid either way — named party, affirmative act, timestamped record.
What are the permitted calling hours?
Federally, 8am to 9pm in the called party’s time zone. Several states are tighter, and a few define the window differently for texts. Set the dialler by the merchant’s time zone rather than yours, which is the mistake floors make when they expand across the country.
