Virtual mailbox in San Francisco, CA: store-network shops vs downtown prestige floors

If you need a virtual mailbox or a business address in San Francisco, you are shopping packing stores from Castro on 584 Castro to Balboa in the Richmond, Irving in the Sunset, Taraval in Parkside, and Bay Street by the Wharf, plus a few downtown prestige floors on Sansome, Geary, Post, and Sutter. You can buy a 941xx line from an app. That line is almost always a CMRA counter or a suite number. A CMRA is a Commercial Mail Receiving Agency: a private business allowed to receive mail for other people. It is not a mailroom VirtualPostMail or US Global Mail staffs on a 941xx street. Decide which product you need, then compare the scorecards.

Updated October 2026 · Verification key: operator-confirmed means the store or the company’s own page names this street. reported means we copied the street from a network map or an older list. We have not looked at every door.

San Francisco stretches across more than one 941xx corridor: Castro, Western Addition on Fillmore, the Richmond on Balboa, the Sunset on Irving, Parkside on Taraval, then Bay Street by the Wharf. Sansome, Geary, Post, and Sutter are prestige floors, not packing counters. Concord, CA is a US Global Mail core room on the Bay Area metro-edge. It is not a San Francisco 941xx company room. The apps sell both store-network CMRA shops and prestige floors. VirtualPostMail’s published mailbox cities are not San Francisco.

What this page is not

It is not a promise that every iPostal1 pin still answers the phone. Network maps churn. Franchise stores rebrand. We list a working set you can check in an afternoon, with the source on each row.

Concord, CA is a US Global Mail core room on the Bay Area metro-edge, the same kind of include as Encino on the Los Angeles page. It is not a San Francisco 941xx company room. We did not find a Pak Mail San Francisco storefront on the official California locator (San Rafael and Pleasanton are the Northern California shops we could name). We did not find a PostNet San Francisco storefront on the official California locator at locations.postnet.com/ca (17 California centers, including San Jose, Sunnyvale, and San Diego). That index has no San Francisco city. A locations.postnet.com/ca/san-francisco URL returned 404. Third-party Alemany Blvd listings are not a PostNet location page. We did not find a company-run San Francisco mail hub on VirtualPostMail or US Global Mail public marketing. Published VirtualPostMail mailbox cities we can name are Covina, CA; Claymont, DE; Brandon, FL; Henderson, NV; and Keller, TX. US Global Mail’s cited core rooms are Houston, New York, and Concord, CA.

Which mailbox product you are buying here

Company-run hub

A mailroom the company staffs. San Francisco does not get one we can name on a 941xx street. The rooms we can cite are VirtualPostMail in Covina, Claymont, Brandon, Henderson, and Keller, not San Francisco, and US Global Mail in Houston, New York, and Concord, CA. Concord is Bay Area metro-edge at most. It is not an SF hub. Mail handling is usually more consistent than a partner store. Banking / KYC and Google Business Profile grades stay F unless the vendor’s own documents say otherwise. KYC means Know Your Customer: the checks a bank uses to confirm who you are. Google Business Profile is the listing Google uses for Maps.

Store network / packing store

A retail CMRA. Counter, boxes, maybe a notary. In San Francisco that is Castro, Bay Street, Fillmore, Balboa, Irving, or Taraval. iPostal1, Anytime, and PostScan all resell stores like these. Mail grade is the store’s. Banking / KYC and Google Business Profile grades stay F.

Office-building listing

A suite number on Sansome, Geary, Post, or Sutter. Sometimes a real receptionist. Sometimes a mailbox behind a locked floor. We did not find an independent office-floor page we could name for those downtown suites. They stay reported unless an operator page exists. Do not assume a bank will accept a callback.

That split is the point of this page. A 94114 Castro packing counter and a 94104 Sansome tower floor share a metro and almost nothing else. VirtualPostMail’s published mailbox cities remain Covina, CA; Claymont, DE; Brandon, FL; Henderson, NV; and Keller, TX. We did not find a VirtualPostMail San Francisco company hub on their mailbox address index. We did not find a Pak Mail San Francisco storefront.

Scorecards for products that actually appear on this map

This is not legal advice. The grades below are product grades. They are not a promise a bank or the California Secretary of State will accept the street.

iPostal1

Store network
Mail
C-
Largest network. Mail quality is the local store's job, not iPostal1's.
Banking / KYC
F
CMRA flag. Wrong product for Mercury, Relay, Stripe Issuing/Treasury, and similar KYC.
Google Business Profile
F
A rented mailbox is a virtual office under Google's written rules.

An app that sends your mail to a local packing store, a UPS Store, a coworking desk, or an office building. The local store handles the mail.

CMRA: Yes, every partner location is a CMRA

Official page

Anytime Mailbox

Store network
Mail
C
Useful if you already trust the local store. Price and quality move with the operator.
Banking / KYC
F
Still a CMRA. Switching from iPostal1 to Anytime does not clear a bank flag.
Google Business Profile
F
Mail-only occupancy is not a Google Business Profile location.

Same store-network model as iPostal1. Each store sets price and day-to-day handling.

CMRA: Yes, partner locations are CMRAs

Anytime Mailbox

PostScan Mail

Some company rooms, mostly stores
Mail
C+
Better if you land in a company room. Partner stores vary, like other store networks.
Banking / KYC
F
A nicer mailroom does not remove the CMRA registration.
Google Business Profile
F
Still a mailbox, not a staffed storefront you operate.

Some rooms the company runs, plus a larger set of partner stores. The stores are independent.

CMRA: Yes, hub and partner addresses are still CMRAs for USPS mail

PostScan Mail

VirtualPostMail is a company-run hub we cite in other cities. It has no San Francisco mailbox on its published address pages, so its scorecard does not apply to the 941xx rows below. PO Plus names mailbox rental and a digital mailbox on its own site. You are grading the store. The logo on the app is secondary. Read the suite line on Form 1583. Form 1583 is the USPS form that lets the store accept mail for you.

Anytime Mailbox publishes both a San Francisco city landing at anytimemailbox.com/san-francisco-ca and a California index. Those pages disagree. The city landing retrieve listed 166 Geary St at US$8.99/mo, 5214F Diamond Hts Blvd at US$10.99/mo, 2021 Fillmore Street at US$19.95/mo, 5432 Geary Blvd at US$9.99/mo, and 18 Bartol Street at US$19.99/mo. The California index retrieve listed 3739 Balboa Street at US$19.99/mo, 584 Castro Street at US$10.99/mo, 2021 Fillmore Street at US$19.95/mo, 5432 Geary Blvd at US$10.99/mo, 28 Geary St at US$13.99/mo, 1388 Haight St at US$10.99/mo, 2549 Irving St at US$14.95/mo, 1728 Ocean Ave at US$19.99/mo, 490 Post St at US$14.95/mo, and 447 Sutter St at US$9.99/mo. Geary Blvd 5432 is two stickers. Geary Street is two different door numbers. We name which URL supplied the sticker. The cited pages list those prices separately. Castro, Balboa, and Irving are the index rows we can name on packing-store pages. Fillmore Postal is 1015 Fillmore, not 2021 Fillmore.

The rest of the table is a curated subset of network pins, not every row on those maps. Sansome Suite 1400, Geary Suite 650, Post Suite 500, Sutter Suite 405, 2021 Fillmore, 1388 Haight, 166 Geary, West Portal, and PostScan’s Mission Street page stay reported. A prestige sticker does not clear Mercury, Relay, Stripe Issuing, or Google Business Profile. Reported only, not a recommendation. Do not recommend these unverified pins. Anytime’s California index also lists 1728 Ocean Ave. That street has a UPS Store location page. We do not treat a UPS Store pin as a store-network recommendation on this table.

If the point is a company-run mailroom rather than a 94114 line, use a published VirtualPostMail mailbox city or a US Global Mail core room. Concord, CA is the Bay Area room US Global Mail names. It is not a San Francisco company room. A Sansome tower pin is not a VirtualPostMail company room in San Francisco.

Prices the pages publish

iPostal1’s San Francisco page publishes a Virtual Mailing Address from $9.99 and a Virtual Office from $39.99. Retrieved September 8, 2026 PT. The retrieve did not print a Virtual Business Address dollar amount we could copy, and it did not print per-pin Standard / Select / Prestige stickers we could copy. The cited pages do not publish those numbers. We did not check out each suite.

Anytime Mailbox has a San Francisco city landing at anytimemailbox.com/san-francisco-ca and a California index at anytimemailbox.com/l/usa/california. Those pages disagree. 5432 Geary Blvd is US$9.99/mo on san-francisco-ca and US$10.99/mo on the California index. The city landing lists 166 Geary St at US$8.99/mo. The index lists 28 Geary St at US$13.99/mo. Those are different door numbers. We name the URL. The cited pages do not publish one price between those figures. Those are landing stickers, not a promise the operator still charges that tomorrow.

PO Plus’s mailbox page publishes Standard at $40 monthly, Business at $55 monthly, and Premium at $76 monthly. PO Plus’s digital mailbox page publishes low volume plans starting at $10.99 per month. Parkside Mailboxes’ homepage publishes a Small mailbox at $39/month on a 1-month term, plus a $25 setup fee. PostScan’s 350 Bay St Ste 100 location page publishes a starter plan at $20/mo. PostScan’s 1875 Mission St location page publishes a starter plan at $10/mo. Those are operator-published prices on their sites, not an iPostal1 national floor.

If you need banking or Google, stop shopping this table

A Castro packing store and a Sansome prestige suite share a metro. Neither one is a bank operating address. A California LLC filing needs an office in this state and an agent for service of process. Service of process means accepting a lawsuit. A post office box alone is not that office. A CMRA packing store is not the same as a registered agent. A 941xx street on Form 1583 is not a promise the Secretary of State or a bank will treat it as your principal office or your place of business. This is not legal advice, and it does not say a CMRA becomes your principal place of business. For the California agent and office split, see the California LLC page. For Amazon or Stripe occupancy, see the commerce page. For Form 1583, start here and the USPS PS Form 1583 (June 2024) before you order checks. For which address banks actually accept, see the product comparison.
