United reservations and customer service

This is a US toll-free number. One third-party listing says it works from the US and Canada only. If you are calling from anywhere else, test that it connects before you need it. If it does not connect, use the contact details on United's own website.

1. Try the United app or website first.
2. Dial +1 800 864 8331 and follow the prompts.

Calls from mobiles, public phones and hotel rooms may attract extra charges. Those charges are set by your phone or hotel, not by United or 002call.

002call sends your call over the internet, so it skips the international call charges your carrier and hotel phone would add. There is no subscription. If you are abroad, Wi-Fi avoids mobile data charges.
