San Francisco is the birthplace of technology companies worth trillions of dollars — and yet, plenty of residents still need to send a fax in 2026. Your landlord won't accept email. The USCIS asylum office requires a faxed submission. Your doctor's office needs those records sent the old-fashioned way.
The good news: fax services in San Francisco are more accessible than you might think, with options ranging from completely free (the public library) to store-based chains to a phone app that eliminates the trip entirely.
Here's the full breakdown.
1. FedEx Office — The Most Reliable Chain
FedEx Office has roughly 15 full-service Print & Ship Centers within San Francisco city limits, making it the most widely available retail fax option. You'll find them concentrated in the Financial District, SoMa, and Downtown, with outposts in the Marina, Cole Valley, and West of Twin Peaks.
Prices
| Service | First Page | Each Additional Page |
|---|---|---|
| Local | $1.89 | $1.59 |
| Domestic (long-distance) | $2.49 | $2.19 |
| International | $5.99 | $3.99 |
| Receiving | ~$1.00 | ~$1.00 |
Notable SF Locations
- Financial District: 120 Bush St, 127 Kearny St, 369 Pine St, 585 Kearny St
- SoMa: 1155 Harrison St, 303 2nd St, 400 Howard St
- Downtown/Union Square: 726 Market St
- Embarcadero: 4 Embarcadero Center
- Marina: 3225 Fillmore St
- West of Twin Peaks: 1597 Sloat Blvd
Watch for Hidden Charges
Failed fax attempts are still billed at FedEx Office. Cover pages also count as a paid page. If your fax bounces, you'll pay for the attempt. Always confirm the destination number before sending.
Verdict: Consistent and reliable with a receipt, but expensive for multi-page documents. Best for the Financial District crowd that needs something sent during a lunch break.
2. The UPS Store — Best Neighborhood Coverage
The UPS Store has over 20 locations spread across nearly every San Francisco neighborhood, giving it the broadest geographic footprint of any retail fax provider. Franchise pricing means costs vary, but expect to pay a bit more than FedEx.
Prices
| Service | First Page | Each Additional Page |
|---|---|---|
| Domestic | $2.00–$3.00 | $1.50–$2.00 |
| International | $7.00 | $5.00 |
| Receiving | $1.00–$2.00 | $1.00–$2.00 |
The higher end of those ranges is common in SF's pricier neighborhoods (Pacific Heights, Nob Hill, the Marina). Call ahead to confirm exact pricing.
Coverage by Neighborhood
| Neighborhood | Address |
|---|---|
| Pacific Heights | 2443 Fillmore St |
| Polk Gulch | 1819 Polk St |
| Nob Hill | 950 Mason St |
| Japantown | 1770 Post St |
| Marina | 2269 Chestnut St |
| Civic Center | 77 Van Ness Ave |
| SoMa | 660 4th St, 2 New Montgomery St |
| Mission Bay | 1225 4th St |
| Financial District | 182 Howard St, 268 Bush St, 3 Embarcadero Ctr |
| Downtown | 222 Mason St |
| Richmond | 3145 Geary Blvd, 5758 Geary Blvd |
| Inner Sunset | 1032 Irving St |
| West Portal | 236 W Portal Ave |
| Noe Valley | 4104 24th St |
| Castro/Duboce | 2370 Market St |
| Bernal Heights | 60 29th St |
| Fisherman's Wharf | 1288 Columbus Ave |
| Cathedral Hill | 1410 Franklin St |
| Lakeshore | 1559 Sloat Blvd |
Verdict: Best option if you need to fax from a residential neighborhood. Hours vary by franchise — most close by 6–7 PM and are not open 24/7.
3. San Francisco Public Library — Free Fax Service
This is the most important thing in this article: the San Francisco Public Library (SFPL) offers completely free domestic fax service at all 28 branch locations. You do not need a library card to use the fax machine — just walk in.
What's Covered
| Feature | Details |
|---|---|
| Cost | Free for any U.S. number |
| Availability | All 28 SFPL branch locations |
| International faxing | Not available |
| Hours | Branch hours (most open 10 AM–6 PM) |
The SFPL's multifunction devices can send faxes to any domestic U.S. phone number at no charge. If you're sending to a hospital, a government agency, a landlord, or a legal firm — and it's a U.S. number — the library is your best option.
Free Fax Tip
The SF Main Library branch (100 Larkin St, Civic Center) has the most available machines and longest hours. Check sfpl.org for your nearest branch and current hours before making the trip.
Verdict: Unbeatable for domestic faxing. The only catch is library hours — if you need to send something at 9 PM or on a holiday, you'll need a different option. See the full guide to library fax services for what to expect.
4. Local Copy Shops & Independent Stores
For more flexibility or pricing transparency, a handful of neighborhood shops offer fax services:
PostalAnnex (350 Bay St, Suite 100 — Fisherman's Wharf / North Beach area, zip 94133) offers both incoming and outgoing fax. Phone: (415) 772-9022. Call for current pricing.
Jensen's Mail & Copy (5214 Diamond Heights Blvd — Diamond Heights) is a long-running neighborhood shop offering fax services. Phone: (415) 282-2100. Good option for residents in the southern hills.
Other Yelp-listed options with fax capability include Copynet, BayCopy SF, and several independent print shops scattered around SoMa and the Mission. Pricing is rarely published online — call first.
5. What About Staples?
Staples Has Left San Francisco
There are no confirmed open Staples stores within San Francisco city limits as of 2026. The Van Ness Avenue location is closed. If you've seen Staples listed on a map app for SF, verify before making the trip — it's likely outdated data. The nearest Staples is in South San Francisco. For the full Staples fax service guide, see what's available outside city limits.
6. Skip the Trip — Fax from Your Phone with mFax
Every option above has a common problem: you need to physically travel somewhere during business hours, pay per page with no discount for multiple documents, and hope the machine is working.
mFax.to eliminates all of that. It's used by over 5 million people and lets you send a fax in under 2 minutes from your phone or browser.
How to send a fax with mFax
Upload your document
Take a photo of your paper document or upload a PDF directly from your phone, Google Drive, or email.
Enter the fax number
Type in the recipient's fax number. For SF government offices, UCSF, or local businesses, just use the number listed on their contact page.
Send and get confirmation
Hit send. mFax delivers with a 98% success rate and emails you a delivery confirmation when it goes through.
This works for domestic and international numbers, 24/7, with no store hours to worry about.
Why SF Residents Use mFax
- Healthcare: UCSF Health, Zuckerberg SF General, and most SF medical practices still require fax for records requests and referrals. Send directly from your phone without visiting a copy shop.
- Immigration: The USCIS San Francisco Asylum Office accepts faxed evidence submissions at (415) 575-1393. mFax handles international and domestic equally.
- Real Estate: SF title companies and escrow agents maintain active fax lines for contract transmission. No need to hunt for a working machine on closing day.
- Government: SFHSS (city employee benefits) accepts faxed enrollment forms at (628) 652-4701.

When to Use Each Option
Use the library if you're sending a domestic fax during the day and want to pay nothing. All 28 SFPL branches offer free service — find your nearest at sfpl.org.
Use FedEx Office if you need an international fax, require a physical confirmation page, or are sending from Downtown/Financial District during business hours.
Use UPS Store if you're in a residential neighborhood and need something sent today. Check your specific franchise's hours first.
Use mFax.to if it's outside business hours, you're sending sensitive documents, you need international faxing at a reasonable price, or you just don't want to leave your home or office. Try mFax.to — the first fax is fast to set up and costs far less than any store in the city.
Skip Staples — there are no open locations in SF city limits.
