Airbnb is now sharing the real last 4 digits of guest phone numbers with us, and we’ve updated our smart lock functionality accordingly. Here’s how it works going forward:
If your code style is set to “guest phone”:
-
For locks that use 4-digit codes, we’ll use Airbnb’s last 4 digits directly. This means everything will continue to work as before, provided Airbnb supplies the digits.
-
If Airbnb does not supply the last 4 digits, we’ll fall back to the temporary phone number Airbnb provides.
-
For locks that use codes longer than 4 digits, codes will be generated either from the temporary phone number or, if none is available, from a random code.
If your code style is set to “random”:
-
Nothing changes - codes will continue to be created randomly as before.
Other booking channels (Vrbo, Booking.com, direct, etc.):
-
We’ll continue to generate codes based on the guest’s real phone number, just like before.
To summarize: If your locks use 4-digit phone-based codes, you don’t need to make any changes - your setup will continue working as expected.
