The National Do Not Call Registry: A Caller’s Field Guide
Most guides to the National Do Not Call Registry are written for consumers. This one is for the people doing the dialing. From the caller’s side, the registry works like this: if you make telephone solicitations, you subscribe to registry data for every area code you call (the first five are free, $82 apiece after that), you re-scrub your lists at least every 31 days, and you dial only between 8 a.m. and 9 p.m. at the called party’s local time. Here is how each piece works — as of July 2026.
This page is education, not legal advice. A dialer is a tool — compliance depends on how you use it. Enzo does not scrub lists against the national or state DNC registries — run every list through a third-party scrubbing service such as Blacklist Alliance before uploading it. Enzo provides campaign-level internal DNC (per-campaign only). Consult a telemarketing attorney for your specific situation.
What the Registry Is, Seen From the Caller’s Side
The registry is the FTC’s national list of phone numbers whose owners have said no to sales calls. A few consumer-side mechanics shape your lists. Registration is free and never expires — a number only comes off if it is disconnected and reassigned, or at the owner’s request — so the list only grows. Cell phones can be registered the same as landlines. Business and fax numbers are not covered; the registry protects residential and wireless subscribers. And a newly registered number appears on the registry the next day, but the FTC allows up to 31 days for sales calls to stop — which is exactly where the scrub cycle below comes from.
One caution on the business-number carve-out: there is no blanket B2B loophole. A decision-maker’s personal cell is a wireless number in the registry’s eyes, whatever they use it for.
Who Must Subscribe: Sellers, Telemarketers, and the SAN
Every seller — the company whose product the calls promote — must have its own registry subscription and Subscription Account Number (SAN). A telemarketing agency can complete the subscription on a seller’s behalf, but the seller’s subscription and SAN stay separate from the agency’s. Telemarketers and service providers accessing the registry for clients must identify those clients and supply the clients’ SANs. And the rule with teeth: it is illegal for a seller to call — or to have a telemarketer call — numbers in an area code unless the seller has subscribed to that area code and paid any required fee.
Exempt organizations sit outside the fee system. Some charities and political callers pay nothing and may obtain the entire list free, though their SANs take roughly three business days to issue. A charity calling on its own behalf is outside the registry altogether, but a third-party telemarketer calling for a charity must still honor do-not-call-again requests. Survey-only calls are exempt; a “survey” that ends in a sales pitch is a solicitation and is covered.
Access and Fees: Buying National Do Not Call Registry Data
Caller-side access runs through one portal: telemarketing.donotcall.gov — note the hostname, telemarketing, not telemarketer (the latter does not resolve). Access is limited to sellers, telemarketers, and service providers; first-time users create a profile identifying the organization as a Seller, a Telemarketer/Service Provider, or Exempt.
For the fee year that began October 1, 2025:
- Data for up to five area codes is free.
- Each additional area code costs $82 per year.
- The annual charge is capped at $22,626 for all area codes nationwide.
- Adding an area code mid-cycle for a half year costs $41.
Fees are paid annually online through Pay.gov, and the annual subscription period runs twelve months from the first day of the month in which you paid. Two operational details: full data files can be downloaded only once in any 24-hour period, and after the first full download you can pull smaller “changes only” delta files instead of the whole set. These fees change every October 1 — check current figures before renewing.
The 31-Day Scrub Rule
Buying access is not compliance; scrubbing is. If you are required to use the registry, you must synchronize your calling lists with an updated version of it at least every 31 days. The FCC’s safe-harbor conditions run on the same clock — protection depends on, among other things, using national registry data obtained no more than 31 days before any call is made and documenting the process.
In practice that means a standing calendar entry: download fresh data (or a delta file), re-scrub every active list, and log the date. Enzo does not do this step for you — no list should reach any dialer until a third-party service such as Blacklist Alliance has scrubbed it against the national DNC registry and any state lists that apply.
The Established Business Relationship Exception
The registry does not bar you from calling your own customers. Under the established business relationship (EBR) exception, you may call a registered number if the person made a purchase or completed a transaction with your company within the previous 18 months, or made an inquiry or application about your products within the previous 3 months. The exception ends the moment the person makes a company-specific do-not-call request — at that point the EBR is over and the number belongs on your internal DNC list.
Calling Hours: Sundays, Evenings, and the 9 p.m. Line
Can telemarketers call on Sunday? Under federal law, yes. There is no weekend or holiday exception — the rule is the same seven days a week: no telephone solicitations before 8 a.m. or after 9 p.m., local time at the called party’s location. How late can a telemarketer call? Federally, until 9 p.m. where the person you are calling actually is — and the burden of determining that local time falls on the caller, not the recipient. Area code is not location: a 212 number can ring in California, and “quiet hours” lawsuits built on exactly that gap surged onto federal dockets in 2025.
Two caveats. State laws can be stricter — Florida’s Telephone Solicitation Act, for one, sets its own hours and call-frequency limits, and more than 15 states now have telemarketing statutes of their own — so verify the rules for every state you call into. And courtesy is stricter than law: a technically legal 8:55 p.m. Sunday dial is still a bad first impression.
What Happens If You Ignore It
One sentence, because the full treatment lives elsewhere: calling registered numbers without an exemption exposes you to private lawsuits at $500 to $1,500 per call plus regulator penalties that can reach $53,088 per violation — see TCPA for Cold Callers for how those numbers stack up.
Where Enzo Fits — and Where It Doesn’t
Enzo’s DNC feature is deliberately narrow: campaign-level internal DNC. Mark a contact DNC inside a campaign and they stay excluded from that campaign, even if they appear again in another list you upload to it. It is per-campaign only — marks do not carry across campaigns — so keep your master suppression file outside the dialer and re-apply it to every new campaign. Enzo does not scrub against the national registry or any state registry, and no dialer subscription substitutes for your own SAN. Subscribe at telemarketing.donotcall.gov, scrub through a third party such as Blacklist Alliance, and let the dialer do what it is built for: putting clean, lawful lists in front of agents quickly.
Treated as a workflow, the National Do Not Call Registry is manageable: one subscription per seller, five free area codes and $82 for each one after, a scrub every 31 days, an 18-month/3-month window for existing customers, and a hard stop at 9 p.m. wherever your prospect actually is. Put those on a calendar, keep the receipts, and the registry becomes a monthly chore instead of a legal exposure. For the rest of the legal picture, start with TCPA for Cold Callers; for process and scripts, the Cold Calling Guide.
