How to Share Contact Info Without Posting Your Phone Number Publicly
Practical strategies to exchange contact details online without risking phone number harvesting.
Why Publishing Your Phone Number is Risky
Automated scrapers crawl forums, social networks, and classified boards 24/7 searching for phone numbers (regular expression matches). Once indexed, your number is added to robocall, phishing, and telemarketing lists.
The Safe Handoff Technique
Avoid posting raw phone numbers in public text. Instead, use a temporary private handoff link or relay room where you choose whether to share details after contextual confirmation. A pairing code does not prove legal identity or trustworthiness.
