NameChk

NameChk (namechk.com) is a username and domain name search tool that checks the availability and registration status of a specific username across dozens of social networks, media platforms, and websites simultaneously. It helps investigators discover where a specific username has been registered.

For OSINT investigators, NameChk is a foundational tool in the cross-platform username investigation workflow. When a target username is identified from one platform, NameChk instantly searches over 100 platforms to identify all other sites where the same username is registered — potentially revealing the subject's full online presence across diverse platforms.

Username consistency investigation across platforms exploits the common practice of using the same username across multiple services. When NameChk shows a username registered on dozens of platforms, each represents a potential source of additional intelligence about the subject — their interests, activities, and connections on each respective platform.

For cybercrime investigations, known threat actor usernames can be checked across gaming platforms, developer sites, forums, and social networks that might not be obvious first places to look. Consistent username usage across both criminal and non-criminal platforms has led to real-world attribution in many historical cases.

New platform discovery ensures investigation coverage of emerging or niche platforms. NameChk's regularly updated platform list includes social networks that may be new or less well-known, ensuring investigators check platforms they might not have thought to include.

The availability vs. registered distinction is investigatively useful — a username shown as "available" on a specific platform has not been registered, which is itself relevant intelligence for establishing the boundaries of a subject's known presence.

Document all platforms searched via NameChk, which showed the username registered versus available, and any profiles reviewed with timestamps.
