Here are some legitimate reasons why someone or a company would want to fake their caller id.

  1. Calls from a large company, especially with multiple branches, where sending the main number makes sense. For example, a hospital might have the primary number 555-1000, with perhaps 250 lines inside the main building, and another 100 at the clinic five miles away. While some of the phones will have “555-10XX” numbers, many won’t have any identifiable line. Having all calls “come from” 555-1000 lets the recipients know it’s a hospital call.
  2. A company with a toll-free telephone number may prefer the caller ID to display this number.
  3. A call center making calls on behalf of many clients may prefer the caller ID to display a different number for each client’s calls.
  4. Commercial answering-service bureaus which forward calls back out to a subscriber’s cell phone, when both parties would prefer the caller ID to display the original caller’s information.
  5. Most calling-card companies display the caller ID of the calling-card user to the called party.
  6. Business owners have been known to use caller ID spoofing to display their business number on the caller ID display when calling from outside the office (for example, on a mobile phone).
  7. Google Voice displays its users’ Google Voice number when they place calls through the service using their landline or cell phone.
  8. Gizmo5 (now defunct) sent the user’s Gizmo5 SIP number as outbound caller ID on all calls. Because Gizmo5 IDs were in the format 747NXXXXXX, it was possible to confuse calls made from Gizmo5 with calls made from area code 747.
  9. The New York Times sent the number 111-111-1111 for all calls made from its offices until 15 August 2011. The fake number was intended to prevent the extensions of its reporters appearing in call logs, and thus protect reporters from having to divulge calls made to anonymous sources. The Times abandoned this practice because of the proposed changes to the caller ID law, and because many companies were blocking calls from the well-known number.[29]
  10. Wirelessly calling 911 involves, in one worst-case scenario, the immediate muster of available, expensive, universal translation and relay resources to determine from the caller’s spoken language, not known to the responding dispatcher, the address of the emergency. Caller ID spoofing the street address of a 911 call known to local GPS, by GPS to street address decoding software, running on the same IP connection as a wireless VoIP 911 call, could save these resources and improve service by delivering GPS-accurate location data to the dispatched responders at the time it is needed. (Only about ten hexadecimal digits are needed.)

What Is Caller ID Spoofing?

Spoofing Caller ID is the ability to cause a telephone or mobile network to display a different number on the receiver of the calls Caller ID display or smartphone that is not the real number. Spoofing is usually a term in which the call is done to cause harm. Most spoof calls are done as practical jokes so the caller can fake their caller id so they can disguise it.  – Wikipedia

On June 13th 2007 the U.S.  Government passed  the “Truth in Caller ID Act” which makes it”

“unlawful for any person within the United States, in connection with any telecommunications service or VOIP service, to cause any caller identification service to transmit misleading or inaccurate caller identification information with the intent to defraud or cause harm.”

Basically changing your caller id is legal as long as you don’t do it to defraud or cause harm.
