Properties request this to confirm your reservation. You may be pre-authorised* to ensure that your credit card is valid and has sufficient funds, or in some cases, your details are used to pay for your stay when you book.
*A pre-authorisation is a temporary hold on an amount to ensure your card is valid and has sufficient funds. The amount held will be returned to your account after a certain period of time, which depends upon the property and your card provider.
For each reservation, Booking.com provides a unique and anonymous alias email address for both you and the accommodation. All messages sent to this alias email will be forwarded to the accommodation, including links, images, and attachments (up to 15 MB).
For security purposes, Booking.com has an automated system that monitors communication for malicious content. This includes spam and the limitation of certain file types, such as: .zip, .rar and .exe.
Please be aware that email communication generated by the accommodation will be sent via Booking.com on their behalf. Booking.com cannot be held accountable for the content of the communication. If you suspect that the content of the communication is inappropriate, suspicious or contains spam, we ask that you report this information by clicking on the link located at the bottom right corner of the email.
These communications will be stored by Booking.com. Booking.com can access communications upon request from either you or the accommodation, and, if strictly necessary, for security or law enforcement purposes, such as fraud detection and prevention.
Booking.com may analyse communications to improve its services. If you do not want Booking.com to monitor or store your communications made via Booking.com, please do not make use of the communication feature offered by Booking.com, including communication via alias email addresses.
