Sometimes a website (e.g. Amazon) will ask for a mobile phone number so they can send you a text message (e.g. to track a shipment), but they also ask you which carrier you use (e.g. AT&T, Verizon, etc.).
If I want to give them my Google Voice number, which carrier should I specify?
As an example, Amazon provides the following options:
- AT&T
- Alltell
- Boost
- Cellular South
- Cincinnati Bell
- Midwest Wireless
- Nextel Communications
- Sprint PCS
- T-Mobile
- US Cellular
- Verizon Wireless
- Virgin Mobile
Note that you must choose one, this is not an optional field. If someone could explain why websites such as these even need your carrier information, that would help as well.

Any site that is asking for your carrier to send you an SMS isn't using a standard SMS protocol they are using an SMS gateway to send the SMS through email (called SMS Transit). Each carrier has it's own specific email to SMS gateway (for example to send a text to the Verizon Wireless phone number (555) 555-5555 you'd email 5555555555@vtext.com).
Google Voice does not support SMS Transit so that is why rchern couldn't get her SMS verification.
So the short answer to you question: none; Google Voice doesn't support receiving text messages from them.
(Personally, I find this very frustrating and wish they'd support it)
