It appears there's really no easy way to determine the origin of a text
sent to a cell...

For shortcodes, Neustar provided a list:

For regular cellular numbers, the Wireless Amber Alert site is popular
amongst MVNO (e.g. prepaid) users to find out so they can use the
email-to-text gateways:

(You don't actually sign up, just enter the number and then it will tell you
the carrier.)

For landlines/VoIP/etc. Google should be able to tell you at least the
city/state. Though it's rare that you will get a text from a landline, it is
possible.
