The use of a telephone number serves as a crucial step in confirming the identity of a YouTube channel owner. This process helps to establish authenticity and reduces the likelihood of impersonation. For instance, upon creating a new channel or attempting to enable certain features, the platform prompts the user to associate a valid phone number with the account. A verification code is then sent via SMS or voice call to that number, which must be entered on the site to complete the process.
This layer of security provides multiple benefits, including enhanced account security, increased access to YouTube features, and the potential for channel monetization. Historically, the introduction of this verification method significantly reduced the proliferation of spam accounts and malicious activities. This safeguard is often a prerequisite for functionalities like live streaming, uploading longer videos, and appealing content ID claims, thereby contributing to a more trustworthy and robust YouTube ecosystem.
