Quick Answer : To stop junk mail, register at DMAchoice.org ($5 for 10 years), opt out of prescreened credit offers at OptOutPrescreen.com (free), and contact persistent individual senders directly. USPS cannot block advertising mail for you — standard marketing mail is a paid service senders purchase, and carriers are required to deliver it. Expect a 60 to 90 day window before volume drops noticeably.
Here's the complete process, what each step actually covers, and why some mail keeps arriving no matter what you do.
Why Can't USPS Just Stop My Junk Mail?
This is the first thing most people want to know, and the answer explains why the rest of the process works the way it does.
Standard mail — the official USPS category that covers advertising, catalogs, and bulk marketing — is a legitimate paid service. Senders purchase delivery for these items the same way anyone pays postage for a letter. Carriers are required to deliver what's been paid for, and they have no authority to filter or withhold items based on a recipient's preference.
This is also why standard mail behaves differently from first-class mail in other contexts. It doesn't forward when you move, it isn't held during a USPS Hold Mail request in the same way, and it can't be refused at the mailbox the way certain other mail categories can.
The practical consequence : stopping junk mail means going upstream to the senders and the data brokers who supply them with your address, rather than asking USPS to intervene at the delivery end.
📬 The one exception worth knowing
USPS does have a process for stopping specific mail you consider obscene or sexually offensive, via PS Form 1500 (Prohibitory Order). This is a narrow legal mechanism for a specific category, not a general junk mail solution — it doesn't apply to ordinary advertising you simply don't want.
What Is DMAchoice and How Does It Work?
DMAchoice is the opt-out service run by the Association of National Advertisers, and it's the single most effective step for reducing general advertising mail volume.
How to register : go to DMAchoice.org, create an account, and register your name and address. The registration costs $5 and lasts 10 years — one of the few genuinely worthwhile small fees in this process, since the alternative is contacting hundreds of individual senders.
What it covers : the service lets you opt out of four categories — credit offers, catalogs, magazine offers, and other mail offers. You can opt out of all four or select specific ones if you'd like to keep receiving catalogs, for instance, while blocking everything else.
What it doesn't cover : DMAchoice only affects member organizations of the Association of National Advertisers. Many large mailers participate, but smaller regional businesses, local political mailings, and non-member companies aren't bound by it. This is why DMAchoice reduces volume substantially without eliminating it entirely.
Register every adult in the household separately. The opt-out is tied to a specific name at a specific address, not to the address alone. A household where only one person registers will continue receiving mail addressed to everyone else.
How Do I Stop Prescreened Credit Card Offers?
Credit offers deserve their own step because they come through a different channel than general marketing mail and require a separate opt-out.
OptOutPrescreen.com is the official site operated jointly by the major credit bureaus — Equifax, Experian, TransUnion, and Innovis. It's free, and it covers prescreened credit and insurance offers specifically.
Two options are available : opt out for five years, which can be completed entirely online in a few minutes, or opt out permanently, which requires printing and mailing a signed form.
Why this step matters beyond annoyance : prescreened credit offers contain enough personal information to enable application fraud if intercepted. This is one of the specific categories organized mail theft rings target, which makes opting out a genuine security measure and not just a decluttering exercise. Our complete guide to mailbox security covers the broader context of what makes certain mail categories disproportionately valuable to thieves.
🔒 The security angle most people miss
Reducing junk mail volume has a secondary benefit beyond convenience : a mailbox that fills up with unwanted advertising is more likely to overflow, stay unchecked longer, and obscure the legitimate mail underneath it. Less junk mail means a mailbox that's easier to keep clear and easier to notice when something's missing.
How Do I Stop Mail From Specific Companies?
After the two broad opt-outs, individual senders account for most of what still arrives — and these require direct contact.
Use the contact information printed on the mailing itself. Most advertising mail includes a customer service number or a website with an unsubscribe option. Calling and asking to be removed from the mailing list is usually the fastest route, and most companies comply promptly since maintaining accurate mailing lists saves them money.
Be specific about what you're requesting. Ask to be removed from their mailing list entirely and to have your information excluded from any list rental or sharing arrangements. The second part matters — some companies will stop mailing you directly while continuing to sell your address to other mailers.
Keep a short record. If the same company continues mailing after a removal request, noting the date of your first request makes a follow-up call significantly more effective.
For catalogs specifically, CatalogChoice.org is a free service that handles opt-out requests for individual catalog retailers on your behalf, which is faster than contacting each one separately when you receive a large number of them.
What About Political Mail and Local Flyers?
Political mail is not covered by any opt-out service. Campaign mailings, ballot information, and candidate advertising fall outside DMAchoice and similar programs. There is no general mechanism to stop it, and volume spikes predictably during election cycles.
Local business flyers delivered by hand aren't USPS mail at all. Anything placed in your mailbox without postage is a separate issue — technically, non-postage items in a mailbox are a violation, since the mailbox is reserved for USPS-delivered mail. For persistent local distributors, contacting the business directly is generally more effective than any formal process.
"Current Resident" and "Occupant" mail is addressed to the address rather than to you by name, which means name-based opt-outs like DMAchoice don't affect it. This category is the hardest to eliminate entirely and often persists even after every other step has been completed.
How Long Does It Take to See Results?
Weeks 1 to 4 : minimal visible change. Mailing lists are typically prepared weeks in advance, so mail already in the pipeline continues arriving regardless of when you opted out.
Weeks 4 to 8 : noticeable reduction begins as DMAchoice and credit bureau opt-outs propagate through sender databases.
Weeks 8 to 12 : most of the reduction from the broad opt-outs has taken effect. What remains at this point is typically non-member senders, political mail, and "Current Resident" items.
Ongoing : volume tends to creep back up slowly over time as new companies acquire your address through purchases, subscriptions, and public records. A periodic repeat of the individual-sender step every year or two keeps it in check.
📮 A note on accumulation
While you're working through the reduction process, a mailbox with adequate capacity prevents the overflow that makes a full mailbox both a security signal and a practical nuisance. Our modern mailbox collection includes higher-capacity designs built for current mail and package volumes rather than the lighter loads mailboxes were originally sized for.
FAQ
How do I stop junk mail permanently?
Register at DMAchoice.org ($5 for 10 years), opt out of prescreened credit offers at OptOutPrescreen.com (free, with a permanent option by mail), and contact persistent individual senders directly. No single step eliminates everything, but the combination reduces volume substantially.
Can USPS stop delivering junk mail to my address?
No. Standard advertising mail is a paid service and carriers are required to deliver it. The only narrow exception is PS Form 1500, which applies to mail you consider obscene, not to ordinary advertising.
Is DMAchoice free?
No — registration costs $5 and lasts 10 years. OptOutPrescreen.com, which covers credit and insurance offers, is free.
How long does it take for junk mail to stop?
Expect minimal change in the first month, noticeable reduction between weeks four and eight, and most of the effect by around 12 weeks. Mailing lists are prepared in advance, which is why the delay exists.
Why do I still get junk mail after opting out?
DMAchoice only binds member organizations. Non-member senders, political mail, local businesses, and mail addressed to "Current Resident" rather than to you by name all fall outside its scope.
Does opting out of credit offers affect my credit score?
No. Opting out of prescreened offers at OptOutPrescreen.com has no effect on your credit score or your ability to apply for credit yourself.
Do I need to register everyone in my household separately?
Yes. Opt-outs are tied to a specific name at a specific address, so mail addressed to other household members continues unless each person registers individually.
