How to Change Caller ID for Free

1. Open your Web browser and navigate to a site that lets you spoof (fake) your caller ID number. Sites such as Covert Calling, SpoofTel, TeleSpoof and TraceBust all enable you to place a call and choose the number you want to appear on the other person's phone display screen (links in Resources). While the sites do charge for their services, you can create a trial account or make a test call free.
2. Type your own phone number in the 'Your Number' or 'Your Phone Number' field.
3. Enter the number of the person you want to call in the 'Your Friend's Number,' 'Destination Number' or other similarly named field.
4. Enter the fake number you want to appear on the other person's caller ID display in the 'Spoof Number,' 'Fake Number' or 'Number to Display' field.
5. Enter the CAPTCHA security text in the appropriate field, if prompted.
6. Click the 'Call Now,' 'Place Call,' 'Try Now' or other similar link or button. Wait a few seconds for your own phone to ring, and then answer it. After you answer your phone, the spoofing service connects you to the number of the other party. When the phone of the other person rings, the 'spoof,' or fake, number you entered appears on his caller ID display.
