Travel and ride apps often check whether a number is mobile, landline or VoIP before sending a code, and many turn VoIP numbers away. TwinNumber numbers are registered as mobile.

Booking.comQuestions
Will my hotel get my phone number?
It can. Hotels.com shares your details with hotels and other travel suppliers to complete your booking, and a supplier may contact you about it. With a TwinNumber on your account, they get your U.S. number rather than your personal one.
Will Hotels.com ever ask for my passcode?
No. Hotels.com says it will never ask for your password or your one-time passcode, and warns that fake Hotels.com phone numbers circulate online, often through misleading search engine ads. Never read a code to someone who calls you.
Do I need separate numbers for Hotels.com, Expedia and Vrbo?
No. If you sign in with the same email, the three share one account, so you manage your profile and trips for all of them in one place.
Do I need to live in the U.S.?
No. TwinNumber works from 150+ countries with just a browser and an internet connection.
Is TwinNumber affiliated with Hotels.com?
No. We test our numbers with popular services and publish the results. Hotels.com is a trademark of its owner.
What if a code doesn't arrive?
Request a new code, then check your inbox and notification settings. If it keeps failing, contact us and we'll look into it.
