What Is a Virtual Mailbox and How Does It Work?
What is a virtual mailbox? It is a service that gives a business or individual a street-format mailing address where a Commercial Mail Receiving Agency (CMRA) receives mail on their behalf, scans the outside of each item, and lets them view, forward or discard it online.
Every virtual mailbox address is a CMRA address, authorized through USPS PS Form 1583, and it works differently from a traditional PO box or a virtual office plan depending on what a business needs it to do. Checked September 25, 2026
Virtual mailbox, PO box and virtual office compared
These three options all provide a mailing address without a physical office lease, but they differ in address format, online access and price. For where each address type is accepted on official forms, see where each address type is accepted.
| Feature | Virtual mailbox | PO box | Virtual office |
|---|---|---|---|
| Address format | Street-format CMRA address with a PMB or # box number on its own line (DMM 508.1.8). | A USPS Post Office box number address; a Street Addressing option, where available, swaps in the Post Office's street address plus the box number (USPS: PO Boxes). | Same CMRA-style street address, sold as a higher plan tier that also allows a company name on the address, not just a recipient name (iPostal1: Compare Plans). |
| View mail online | Included Providers scan the outside of each envelope for online viewing. | Not offered USPS describes checking the box in person, with most locations open for 24/7 access; it does not describe an online scanning feature (USPS: PO Boxes). | Included Sold as the same underlying mailbox and scanning service, at a higher plan tier. |
| Packages from private carriers | Depends Package acceptance and size limits vary by provider. | Depends Only with the Street Addressing option, where available (USPS: PO Boxes); otherwise oversized items go to counter pickup or a parcel locker. | Depends Runs on the same provider network as the standard virtual mailbox plan. |

How to read this board
"Included" or "Allowed" means the feature comes with the plan as described on the provider's own pages. "Not offered" means the source describes the service without that feature. "Depends" means the outcome varies by specific provider, plan or Post Office location, so it is worth confirming before signing up. The example prices come from iPostal1's published plans, checked September 25, 2026; PO box prices are set by each Post Office location and are not published as a single figure.
How a virtual mailbox works, step by step
- Sign up and choose an address. A customer picks a CMRA location from the provider's network, for example iPostal1's network of 4,250 or more locations (iPostal1: Virtual Mailbox), and selects a plan sized to expected mail volume (iPostal1: Virtual Mailing Address Plans).
- File Form 1583. USPS PS Form 1583 authorizes the CMRA to receive mail as the customer's agent. See how to complete Form 1583 for the ID and signature verification steps.
- Mail arrives at the CMRA location. Mail addressed to the customer's PMB or # number arrives at the provider's facility.
- The provider scans the envelope. The outside of the envelope or package is photographed and posted to the customer's online account.
- The customer chooses open and scan, forward, or shred. An open-and-scan request shows the contents online; iPostal1 charges $2.25 for up to 10 pages then $0.25 per additional page, and PostScan Mail charges $2.00 for up to 10 pages then $0.25 per additional page (iPostal1 pricing, PostScan Mail pricing). Forwarding is billed at carrier rates by iPostal1, or $2.00 for the first item plus $0.50 per additional item plus postage by PostScan Mail. iPostal1 discards unwanted mail at no charge but bills secure shredding per order, the same way it bills an open and scan (bundles of 5 scan or shred orders cost $10), and PostScan Mail charges $1.00 per item for the first 10 pages, then $0.15 per page.
- Checks can be deposited. iPostal1 lists check deposit as available "where available" for $4.95 to deposit up to 5 checks, plus the cost of the scan and trackable shipping (iPostal1 pricing). PostScan Mail's pricing page does not publish check deposit availability.
What it costs
Starting prices vary by provider and by mail volume. iPostal1's Green plan starts at $9.99/mo for 30 mail items, with Blue at $14.99/mo for 60 items, Silver at $24.99/mo for 120 items and Gold at $39.99/mo for 240 items; annual billing gives 2 months free (iPostal1 pricing). PostScan Mail's Starter plan is $10/mo for 30 items with no free open-and-scans included, Standard is $20/mo for 60 items with 5 free scans on monthly billing, and Premium is $30/mo for 120 items with 10 free scans on monthly billing (PostScan Mail pricing). Extra mail items, additional scan pages, forwarding and storage are billed on top of the plan price. Estimate your virtual mailbox cost at your volume before choosing a plan.
Who uses a virtual mailbox
Remote and home-based businesses use a virtual mailbox to keep a professional address off a home address. LLC owners use one for a mailing address on state and IRS forms, though registered agent and some physical-address fields still require a true street address; see virtual address for LLC for which fields accept which address. Frequent travelers and expats use one to receive and manage mail without a fixed home address, viewing scanned mail from wherever they are.
Limits: CMRA rules, downsides and where it does not work
A virtual mailbox address is a mail-receiving location, not a business's own physical place of business, and that distinction is the source of most of its limits.
CMRA flagging and Form 1583
USPS Delivery Point Validation (DPV) data keeps a table of CMRA locations, and CASS and DPV certified address-verification software checks a submitted address against that table and can flag it as a CMRA, even when the address is formatted correctly (USPS PostalPro: DPV). Every customer receiving mail at a CMRA address, and every authorized individual listed with them, must be covered by a signed Form 1583, with two forms of ID including one government-issued photo ID; the signature has to be confirmed in the physical or virtual presence of the CMRA agent or a notary before mail service can start (USPS PS Form 1583). Both of these are genuine downsides to weigh: a CMRA flag can cause friction on forms that check for it, and the ID and verification steps add setup time that a home address does not require.
Bank accounts
The federal Customer Identification Program rule requires a bank to collect "a principal place of business, local office, or other physical location" for a business customer. No federal rule bans CMRA addresses outright; acceptance is each bank's own risk-based policy, and a bank may ask for more documentation when a CMRA address is used (31 CFR 1020.220).
Google Business Profile
Google's guidelines state that "P.O. boxes or mailboxes located at remote locations aren't acceptable" for a listed business address, so a plain virtual mailbox generally does not qualify on its own (Google: Guidelines for representing your business).

FAQ
What is a virtual mailbox address?
A virtual mailbox address is the street-format address of a Commercial Mail Receiving Agency, formatted with a PMB or # box number, where a provider receives mail on a customer's behalf under USPS rules and lets the customer view scanned mail online.
How does a virtual mailbox work?
A customer signs up, chooses a CMRA location, and files USPS Form 1583 to authorize the provider to receive mail for them. Mail arriving at that address gets its envelope scanned and posted online, and the customer chooses to have each item opened and scanned, forwarded, or shredded.
Are there downsides to using a virtual mailbox?
Yes. A CMRA address can be flagged by USPS Delivery Point Validation data even when it is formatted correctly, which can cause friction on forms that check for it. Setting up service also requires filing Form 1583 with two forms of ID, including one government-issued photo ID, and getting the signature verified in person, by video, or through a notary before mail service can start.
Can I pick up mail from a virtual mailbox?
Pickup availability varies by provider and location. The research behind this page does not confirm a single pickup policy that applies across providers, so confirm in-person pickup options directly with the specific provider and CMRA location before relying on it.
What does a virtual mailbox cost?
Starting prices vary by provider and mail volume. iPostal1's lowest plan is $9.99/mo for 30 mail items, and PostScan Mail's lowest plan is $10/mo for 30 items, with extra items, scans and forwarding billed on top. Use the cost calculator to estimate a total at a specific volume.
