5 Corporate Uses for Caller ID Spoofing

by ,

There are a multitude of reasons spoof calling or modifying one’s caller ID has become a contemporary telecom phenomenon. While some may immediately see it as a prankster’s, or worse, a fraud’s tool, Caller ID Spoofing was actually invented to protect private individuals’ privacy and aid businesses.

Listed below are 10 legitimate and completely legal ways “spoofing” is put to good, everyday use:


  1. Large companies with several branches or internal divisions would prefer that their outgoing calls just use their main trunk line. This is especially effective if the locality is used to certain digits signifying a call from specific establishments such as from a hospital.
  2. Companies listed under a toll-free telephone number would most likely sign up to have this number displayed on their outgoing calls in order to funnel call-backs into their toll-free line.
  3. Call center companies that handle multiple clients usually employ caller ID spoofing to organize calls made on behalf of clients, in that they plug in a different number to be associated to each client.
  4. Companies that offer commercial answering services for high-volume accounts normally change caller ID information because this service usually forwards received calls from individuals to their big clients, while retaining the original call’s information.
  5. Calling card or phone card companies actually mask your real number. When you make a call on your personal cellphone or telephone with a phone card, the recipient of the call will only see the company’s number – likely something that appears out of state or out of the country.
