Terms of Use

You may use the website and public API to check operator prefixes, validate number format and view public caller-ID hints.

• Do not use results to harass, stalk, threaten or dox anyone.
• Do not try to obtain NID, SIM registration, bank or OTP data through this service.
• Do not flood the API, rotate IPs to evade limits, or wrap the endpoints as a paid scrape product.
• Do not present lookup output as a government identity certificate.

Operator prefix data follows public BTRC-style allocations. Mobile Number Portability can make the current network different. Caller names can be missing, outdated or user-submitted. The service is provided as-is and free of charge.

Developers may integrate the public API with caching and reasonable rate limits. We may throttle or block abusive clients without notice to keep the free tier available.
