Is there a do-not-mail registry? What actually works

No. There is no national do-not-mail registry in the United States — nothing that works the way the National Do Not Call Registry works for phone calls, where one sign-up applies to telemarketers across the country.

What exists instead is a handful of narrower systems, each covering a different slice of your mailbox. Here's what each one stops, what it doesn't, and the part of your mail that no list can reach.

Why there's no Do Not Call for mail

The Do Not Call Registry works because federal law makes it binding: telemarketers are required to check it before they call.

Nothing like that exists for mail. Junk mail is regulated piecemeal — one federal law covers one kind of offer, an industry group runs a voluntary list for the companies that choose to use it, and everything else is up to each individual sender. So "registering for the do-not-mail list" turns out to mean several different things, and none of them covers everything.

The one legal opt-out: credit and insurance offers

Pre-approved credit card and insurance offers are the exception. They're built from credit-bureau data, and the Fair Credit Reporting Act gives you the right to stop the bureaus from supplying your file for them.

The four bureaus run that opt-out jointly at OptOutPrescreen.com, or by phone at 1-888-5-OPT-OUT (1-888-567-8688). Five years is free online; a permanent opt-out means printing, signing, and mailing the confirmation form.

This is the closest thing to a real do-not-mail registry that exists, and it's legally binding — but it covers prescreened offers and nothing else. We cover it step by step in how to stop prescreened credit card offers.

The industry registry: DMAchoice

The Association of National Advertisers runs DMAchoice, a mail preference service. You register your name and address, and participating marketers drop you from the lists they use to find new customers. As of this writing, registration on DMAchoice.org costs $8 online or $9 by mail, and lasts ten years.

It's worth doing, as long as you know its three limits:

• It's voluntary. Companies that use the list honor it; companies that don't are under no legal obligation.
• It covers prospect mail — companies trying to reach you for the first time. Companies you've bought from, subscribed to, or donated to in the past two years can keep mailing you.
• It doesn't cover prescreened credit and insurance offers. Those go through OptOutPrescreen, above.

DMAchoice also runs separate registries for someone who has died and for someone in your care, which take that person's name off participating mailers' lists.

The federal list most people never hear about

The Postal Service does run a do-not-mail list — but only for one kind of mail: sexually oriented advertisements. Using PS Form 1500, you can add your name to that list. And if a specific mailer sends you an advertisement you consider "erotically arousing or sexually provocative," the same form asks for a prohibitory order barring that mailer from sending you any further mail.

It's real and it's binding, and USPS explains both options in Publication 307. But it exists for that one category. It isn't a general do-not-mail list.

Everyone else: one sender at a time

That leaves the long tail: the regional furniture store, the local realtor, the alumni association, the catalog company that bought a list you were on. Most of them aren't covered by any registry, because most of them were never part of one.

For those, the route is a direct opt-out request to each sender — a formal request to remove your name and address from their mailing list, sent to the privacy contact or mailing address they publish. It's the most tedious part of stopping junk mail, and it's the part that clears the stubborn senders. The complete guide to stopping junk mail covers how.

What no list can stop

Mail addressed to "Postal Customer" is usually USPS Every Door Direct Mail — advertising delivered to every address on a carrier route, which a mailer can send without any names or addresses at all. Since it isn't sent from a list with your name on it, there's no list to be removed from. No registry covers it, and no service — Ferna very much included — can stop it.

One distinction is worth knowing before you write a piece off. Coupon packs such as Valpak's blue envelope are often addressed to "Current Resident" too, but they're mailed from an address list, and Valpak runs its own removal form. Check who sent an unaddressed piece before deciding nothing can be done.

Where Ferna fits

Ferna isn't a registry either. Nobody can offer one, because no law creates one. What we do is the work the registries leave over: the prescreened credit and insurance opt-out across all the major bureaus in a single request, and an opt-out request to each individual sender you name, with each sender's status in your dashboard as it goes quiet.

Your first three requests are free.

If you're looking for one form that stops everything, it doesn't exist. Start with OptOutPrescreen, which is free and legally binding, register with DMAchoice, and then deal with the senders that remain one at a time.
