How determine mobile carrier from cell phone number? RRS feed

  • Question

  • When a candidate gives us his or her cell number, we then use that for their login.  But when they then go to log in with that number, we need to send them a text with a temporary code.  For system-generated text, we email to e.g. 7024559876@vtext.com.  But that's only if we know that's a Verizon number.  Every carrier has there own text@ address.

    So I can either email to all 5 or 6 of the major carriers hoping/knowing one of then should reach the recipient, or I can find an API lookup so will email only the correct account.  Is it normal to do do the former that I suggested?  If not, is there a recommended API to hit?  Preferably one I can get from NuGet?

  • Hi rcook349,

    Sorry for delay in reply.

    According to your description, it is more related to program development, since this forum is about usage tools in VS IDE, so could you provide the some detailed information about your development environment with me,such as development language? And then I will move it to appropriate forum for better support.

    Look forward to your reply.

    Best Regards,
