Common mistakes

• Local format without country code → false «no» results.
• Mixed countries in one file → API rejection or wrong output.
• Confusing Amazon 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.

Reading yes/no

"No" on Amazon may mean no account, privacy settings, or upstream lag. Do not auto-block on one field alone.
