Phone number data refers to the collection of contact information associated with mobile phones, landlines, or internet-based calling systems like VoIP.

Types of Phone Numbers:
Mobile Numbers: The most commonly used in digital marketing due to their association with SMS, apps, and direct calling.
Landlines: Less frequently used, mainly in B2B contexts or older demographics.
VoIP Numbers: Associated with internet-based services like Google Voice nepal consumer mobile number list or Skype, these can sometimes complicate targeting.
How Phone Data is Collected
Marketers collect phone number data through a variety of channels:
Lead capture forms on websites
Mobile app registrations
Point-of-sale systems
Surveys and contests
Third-party data brokers

Using phone numbers in marketing comes with strict legal responsibilities. Key frameworks include:
GDPR (General Data Protection Regulation): Governs data use in the EU, requiring informed consent and data transparency.
