My caller ID shows I am calling from a law office when we are not a law office. Why is it not using what is in ring central caller id

Some TelCo copmanies (wireless carriers included) will not use the presented name because of the number of spammed calls that happen daily. Instead, they will look it up using online databases. In which case, it sounds like someone has registered your phone number with their business name in a 411 database.

Try doing a google search on your phone number to see what comes up. Be sure to use the format xxx-xxx-xxxx when searching - gets better results than using brackets.
