Fixing common booking problems

When the Book button does not work, a date is blocked, or checkout stops.

Updated October 10, 2026

If you cannot complete a booking, go through these in order.

  • You are not signed in or verified. Sign in, then finish identity and license verification. See Verifying your ID and driver’s license.
  • You do not meet the age requirement. Booking requires you to be at least 21 with a valid, unexpired license.
  • The dates are not free. Another guest booked them, or the host blocked them. Try nearby dates.
  • No payment method. Checkout asks you to add a card before you can complete the booking.
  • The card was declined. See My payment was declined.
  • Pickup time outside the host’s hours. If the booking page flags your time, choose one within the hours the host offers, or message them first.
  • Delivery address too far. Hosts set how far they will deliver. Pick a closer address or choose pickup.
  • The page did not load properly. Refresh, try another browser, and make sure cookies are enabled. See Cookies.

If it still fails, email support@seifly.app with the car, your dates, and a screenshot of the message you see.
