Common mistakes

• Local format without country code → false «no» results.
• Mixed countries in one file → API rejection or wrong output.
• Confusing WhatsApp registration with «number is reachable» — different signals.
• Treating «no» as permanent block without re-check after 7–14 days.
• Bulk-check without legal basis (GDPR / local telecom rules) — validation does not replace consent.

Profile fields & ethics

Extended output (activated · age · category · gender · hair_color · skin_color · avatar) adds demographic and media signals. Use for segmentation, not discriminatory filtering. Age/gender are model estimates, not KYC proof.
