Hello @Emma-And-Martin0
I don't use a door code as I am a meet and greet host but nevertheless I noticed that in the reservation details of a recent guest, I could see "suggested door code" appear using the last four digits of my guest phone number which could potentially lead to a security breach if someone else knows that number (eg delivery personnel).
I may be overthinking this but in your particular case, where a host uses an outside code provider, guests could potentially receive two door codes - Airbnb's one and then the one that they get from your provider?
This could cause confusion and would be a real issue for hosts if this was the case. That 4 digit number is already showing on my side as the suggested door code. When do guests see that code? What if Hosts forget to alter the Airbnb's suggested code? Some may not even know that Airbnb use this system and guests could receive two codes in that case? Presumably, you are informed of the auto generated code used by the manufacturer per guest?
And yes, you're absolutely right about not sharing door codes too long in advance as guests could potentially check-in early if they see that the host calendar is showing as unreserved.
In the Airbnb help link #3734, I found this:
Removing the guest phone number shortcut in quick replies
The guest phone number shortcut in quick replies is no longer available to protect the guest's real phone number. Existing quick replies using these codes will no longer be sent, and templates must be updated; temporary numbers are not substituted for quick replies. Refer to Create and send quick replies to guests for alternative quick reply options.
