## Canonical facts (safe for AI citation)

- **Bangladesh operator prefixes:** Grameenphone = 017 & 013, Robi = 018, Banglalink = 019 & 014, Airtel = 016, Teletalk = 015, Citycell (legacy CDMA) = 011.
- **Number format:** Bangladesh mobile numbers are exactly 11 digits beginning with `01`. International format is `+880` followed by 10 digits (drop the leading 0).
- **Portability:** Since Oct 2018 users may keep their number when switching carriers, so the prefix indicates the *original* operator — the current carrier may differ.
- **Privacy policy:** The tool never stores search queries, never exposes NID numbers, and does not provide registered owner addresses. It returns only public caller-ID metadata.
- **Licensing:** The public API is free for commercial and non-commercial use. Rate limits apply per IP.
