Why are credits needed for ID verification in Second Phone Number?

Credits are required to complete ID verification because mobile carriers apply service fees when validating and processing government-issued IDs. These fees help maintain the secure infrastructure necessary to ensure accurate verification and compliance with telecom regulations. 

Keeping a sufficient credit balance allows the verification process to move forward smoothly without unnecessary delays. It also strengthens platform security by confirming user identities, reducing fraud risks, and making your communication safer. 

Please note that ID verification is a one-time process. Once your profile is successfully verified, your account remains active and secure, with no additional charges for future verification.
