How to Use a PO Box or Virtual Address for Privacy
The short version
A PO box or virtual mailbox gives you a mailing address that is not your front door. Use it on every form that only needs to reach you by mail, and your home address stops leaking into commercial databases. It will not work everywhere: banks, the IRS, driver's licenses, voter registration and registered agents all require a street address by rule. Neither option erases the address history people-search sites already hold, so pair the new address with opt-outs.
Why your home address is the master key
Your home address is the field that ties everything else about you together. A name is shared by thousands of people; a name plus a street address is close to unique. That is why people-search profiles are organised around address history, and why a stalker, a scammer or an angry stranger needs your address before anything else can go wrong.
Consumer Reports describes the people-search business plainly: these sites "collect data from public records, commercial data sources, and even social media websites," then bundle it under your name. Lawfare's Justin Sherman lists the government records involved - voting registries, property filings, motor vehicle records, court documents and more.
Some of those records you cannot avoid. But a large share of the commercial data comes from addresses you typed into forms yourself: shopping accounts, subscriptions, loyalty cards, warranty registrations. Every one of those is a chance to give out a different address instead. That is the whole idea behind a private mailing address.
PO box or virtual address: which one you actually need
A PO box is a locked box at a post office you visit in person. A virtual mailbox is a private business that receives your mail at its street address, scans the envelopes, and opens or forwards items on request. Choose the PO box for cost and simplicity, the virtual mailbox if you travel or want mail on your phone.
Both do the same privacy job: they put a non-home address on the forms you fill out. The differences are cost, convenience and who sees your mail. With a PO box, only the Postal Service handles it. With a virtual mailbox, a private company employee opens and scans anything you ask them to, so you are trusting that company with the contents.
Giving out a relative's address instead is not a real option. It transfers the exposure to them and, as our guide on why relatives appear in people-search results explains, brokers will link the two of you anyway.
How to get a USPS PO box
You apply with PS Form 1093, either at the counter or by starting online and finishing at the post office within 30 days. You need two forms of ID: one with a photograph and one that proves your physical address. Boxes come in five sizes and rent in 3, 6 or 12-month terms, with the 3-month option requiring automatic renewal.
USPS is clear that Social Security cards, credit cards and birth certificates do not count as ID. Note the irony: to get an address that hides your home, you must show the Postal Service a document proving where you live. That is by design, and it is one reason the Postal Service's records are worth more to an investigator than a broker's.
Prices depend on the box size and the fee group of the post office. USPS publishes a rate table for its standard ("market dominant") locations; premium locations in big cities price separately and only show up in the location lookup on usps.com.
| Box size | Cheapest fee group, 3 months | Most expensive fee group, 3 months | 6-month range |
|---|---|---|---|
| Size 1 (XS, 3" x 5.5") | $21.00 | $50.00 | $31.00 to $81.00 |
| Size 5 (XL, 12" x 22.5") | $96.00 | $339.00 | $156.00 to $553.00 |
Source: USPS, "Market Dominant PO Box Prices as of 7/12/26" (faq.usps.com), fee groups 7 and 1. Premium and competitive locations are priced separately.
For most people a Size 1 box is enough; USPS says it holds 10 to 15 letters, and larger parcels are held at the counter.
Street Addressing: getting UPS and FedEx to deliver
Private carriers will not deliver to "PO Box 59". At participating post offices you can opt in to Street Addressing, which lets you use the post office's own street address plus your box number - for example "500 Main Street #59". UPS, FedEx, DHL and Amazon will then deliver packages to the post office for you.
The customer agreement has two rules that matter for privacy. First, the address must use the "#" sign and the box number; you may not write "Suite" or "Apt" to make it look like an office or apartment. Second, and in USPS's own words, "You may not use the PO Box 'street address' option as your physical residence or place of business in Legal documents." Doing so can get the box closed.
Street Addressing is not available for Caller Service, Reserve Number or free Group E boxes, and items over 70 pounds, alcohol and other non-mailable goods are refused.
How virtual mailboxes work, and what you sign
Virtual mailbox companies are Commercial Mail Receiving Agencies, or CMRAs, regulated by the Postal Service. Before they can accept your mail you must complete PS Form 1583, show two forms of ID, and have your signature witnessed. Since May 1, 2024, that witnessing can happen over live video with the mailbox operator or a US notary instead of in person.
One ID must be a government-issued photo ID, and the second must confirm the address you list on the form. The CMRA uploads copies of both into a USPS customer registration database and must keep the form available for postal inspectors. Again, your real address is on file - just with the Postal Service and the operator, not on a public website.
Your address at a CMRA is written with "PMB" or "#" before your box number. Postal rules forbid dressing it up as a suite or apartment number, and some banks and agencies check for known CMRA addresses.
Pricing is set per location. Entry plans we checked in September 2026: iPostal1 from $9.99 a month, PostScan Mail "as low as" $10, Traveling Mailbox's basic plan at $15, and LegalZoom's virtual mail service (formerly Earth Class Mail) from $39. Premium city addresses cost more, and opening and scanning mail is usually metered.
Where a PO box is not legally accepted
A PO box is a mailing address, not a residence, and several institutions are required by rule to record where you actually live. Trying to use the box in these places will fail or, worse, could count as a false statement. Give the real address, then check whether the agency lets you list a separate mailing address.
| Where | The rule | Separate mailing address allowed? |
|---|---|---|
| Bank or brokerage account | Federal customer identification rules require "a residential or business street address" for an individual (31 CFR 1020.220) | Usually yes, for statements |
| Federal tax return | Form 1040 instructions: "Enter your box number only if your post office doesn't deliver mail to your home" | No - the box is only for people without home delivery |
| Driver's license | Texas rules require the residence address; a PO box "may only be listed in addition to" it. California's DMV 14 form says "Do Not Use P.O. Box" for the residence line | Yes, in both states |
| Voter registration | The federal form says "Do not use a post office box" for the home address | Yes, in a separate box |
| LLC registered agent | Florida: "The registered agent must have a physical street address in Florida. (Do not list a P.O. Box address.)" | Depends on state |

Notice what these five have in common: voter files, DMV records and business filings are exactly the public records that feed people-search sites. You cannot keep your home address out of them. What you can do is keep it out of everything else, and then use the opt-outs those records trigger, such as our VoterRecords opt-out guide.
Rolling out the new address without leaking the old one
Start with the accounts that mail you the most and the ones most likely to sell data: retailers, subscriptions, loyalty programs, insurers and utilities. Update the mailing address on each. Then file a USPS Change of Address to the box, which USPS accepts as a new address, so stragglers get redirected while you work through the list.
Two cautions. USPS says a PO box "may not be used primarily for the purpose of forwarding mail on to a different address," so the box has to be your real destination, not a relay. And do not put the Street Addressing version on anything legal or financial; use the plain "PO Box" form there, or your home address where the rule requires it.
If you are moving, set up the box before the move and never give the new home address to anyone who only needs to mail you. Our guide to protecting your privacy when moving covers the order of operations.
Who can find out who holds the box
Postal regulations limit who gets a box holder's name and address. Under 39 CFR 265.14, USPS releases it to a federal, state or local government agency on written certification that it needs the information for its duties, and to someone serving legal process who certifies in writing that it is for actual or prospective litigation.
A false request is a federal crime, and USPS's own form warns of fines up to $10,000 or five years in prison under 18 U.S.C. 1001. There is no fee for a legitimate request. For a CMRA, the Form 1583 privacy statement says your information is not disclosed without consent except in legal proceedings involving the Postal Service, for law enforcement, and similar limited cases.
The practical reading: a PO box shields you from casual and commercial lookups, not from a court or a determined litigant. That is the right level for almost everyone. If you are fleeing violence, ask your state about its address confidentiality program instead, which provides a legally substitutable address.
What a new address does not fix
A mailing address is a forward-looking control. Every people-search profile that already lists your home address keeps listing it, and every past address in your history stays there too. Switching to a PO box stops adding to the pile; it does not shrink it. For that you need the opt-outs.
Work through our page on opting out of people-search sites and the individual broker opt-out guides, starting with the sites that rank highest for your name. Our guide on the best way to remove your address online explains which listings matter most.
Then keep the two sides separate: the box for commerce, the home address for the government. Treat your phone number the same way, with a masked line for forms and a carrier line for security, as covered in our post on masked phone numbers.
A realistic setup for most people
The version that works for most households is cheap and takes an afternoon. Rent the smallest USPS box at a convenient post office, or a basic virtual mailbox if you move around. Put it on every commercial form. Keep your home address on the five things that require it. Then clean up the history that is already out there.
- Rent the box first. Bring a photo ID and a second document that proves your address. Opt in to Street Addressing if you get parcels.
- Update commercial accounts. Retailers, subscriptions, loyalty cards, insurers, utilities. File a USPS Change of Address to catch the rest.
- Leave the legal five alone. Bank, tax return, license, voter registration, business registration keep the real address, with the box as mailing address where allowed.
- Opt out of the sites that already list you. Use the people-search opt-outs, then re-check every few months, because listings come back.
- Watch for new exposure. A free exposure scan shows which brokers are likely to list you and whether your email is in a known breach, and stores nothing you type.
See what is already out there
A new mailing address protects you from tomorrow's leaks. Run a free exposure scan to see which data brokers likely list your current address today - no account, nothing stored.
Frequently asked questions
Can I put a PO box on my driver's license?
Generally no. States record your residence address on the license record. Texas rules say a PO box may only be listed in addition to a residence address, and California's change-of-address form says not to use a PO box on the residence line. Both let you add a separate mailing address.
Can I open a bank account with only a PO box?
No. Federal customer identification rules at 31 CFR 1020.220 require a residential or business street address for an individual. Most banks will accept a PO box as a separate mailing address for statements once the account is open.
Can I use a PO box on my federal tax return?
Only in one situation. The Form 1040 instructions say to enter a box number only if your post office does not deliver mail to your home. Otherwise the IRS wants your home address.
Can I register to vote using a PO box?
Not as your home address. The National Mail Voter Registration Form says "Do not use a post office box" in the home address box, because that address decides your voting district. You can list the PO box as your mailing address in the separate box provided.
What is the difference between a PO box and a virtual mailbox?
A PO box is a locked box at a post office that you empty yourself. A virtual mailbox is a private company that receives mail at its street address, scans the envelopes, and opens or forwards items on request. The PO box is cheaper; the virtual mailbox lets you read mail remotely and accepts carrier packages by default.
Can UPS and FedEx deliver to a PO box?
Not to a "PO Box" address, but many post offices offer Street Addressing. You opt in, then use the post office's street address followed by "#" and your box number. USPS says private carriers such as UPS, FedEx, DHL and Amazon can then deliver there.
Does a PO box remove my home address from data brokers?
No. It stops your home address spreading to new commercial databases, but every people-search profile that already lists it keeps doing so. You still need to opt out of those sites directly and re-check every few months.
Who can find out who owns a PO box?
Under 39 CFR 265.14, USPS releases a box holder's name and address to government agencies that certify in writing they need it for their duties, and to people serving legal process who certify it is for litigation. Ordinary members of the public and commercial data buyers cannot request it.
