SFO parking promo code: calculate the checkout savings.

“Two days free plus 10% off” sounds simple until minimum stays, paid-day math, taxes, fees, and blackout rules hit the total. Estimate the offer, then compare it with checkout.

No mystery codes: This page does not publish unverified coupon codes. SFO says online promotions appear only sometimes. ParkSFO currently publishes free-day and percentage offers, but its listed rates exclude taxes and fees. Always use the final checkout total.

Check the operator—not a code dump.

SFO's support page says to check its booking site for promotions available during the stay. ParkSFO currently publishes offers ranging from one free day for a three-day stay through five free days for a 14-day stay, plus some combined percentage offers. Terms and availability can change.

Before reserving

Common questions.

Does SFO always have a parking promo code?

No. SFO says it sometimes offers online promotions and directs travelers to check the booking site for their stay. A third-party code listing is not proof that a code works for your dates.

How does the calculator combine free days and percent off?

It removes the entered free days, applies the percentage to the remaining paid-day subtotal, then adds the entered taxes and fees. Compare that estimate with checkout because the operator's calculation order can differ.

Why are taxes and fees separate?

ParkSFO's published self-parking rate excludes taxes and fees. Enter the amounts shown at checkout instead of treating the listed daily rate as the final price.

How do I compare the discounted quote with other options?

Use the full SFO parking calculator for BART, official SFO, and private-lot totals, or the parking vs rideshare calculator for a door-to-door comparison.
