Everything you need to know about caller ID spoofing in 2026. From choosing a service to making your first spoofed call.
Caller ID spoofing is the practice of changing the phone number that appears on the recipient's caller ID display when you make a call. Instead of showing your real number, the recipient sees whatever number you choose to display. This is done through SIP (Session Initiation Protocol) technology, which allows you to set the outbound caller ID field in the SIP headers before the call is placed.
SIP-based spoofing is the most reliable and flexible method available. Unlike apps that route calls through their own servers with limited control, SIP spoofing gives you direct control over the caller ID field for every call you make. You can change it as often as you want, use any number from any country, and make calls from any SIP-compatible device or software.
When you make a SIP call, the call setup includes a "From" header that carries the caller ID information. SIP spoofing services like SpoofGlobal let you set this field to any number you choose. The call then routes through VoIP trunks that support caller ID passthrough (called CLI routes), and the recipient's phone displays your chosen number.
