Step 2 — Understand Why

Why Verification Codes Are Not Received

If free fixes didn't work, your number is almost certainly the problem. Here's what platforms are actually doing when your code doesn't arrive.

Cause 01

VoIP / Virtual Numbers Are Blocked

Most platforms run real-time carrier lookup. VoIP numbers are rejected before the code is even sent — the verification code is never dispatched, with no error shown. Learn more: Non-VoIP numbers explained →

Cause 02

Carrier Filtering

Some telecom operators silently block incoming OTP messages — particularly bulk SMS and international verification traffic — with no delivery failure notification to you. The code is sent but never delivered.

Bulk SMS blockedInternational OTP traffic
Cause 03

Platform Restrictions

Apps like WhatsApp, Google, and PayPal run their own number screening on top of carrier lookup. Numbers that are suspicious, reused, or fall within known VoIP ranges are blocked at the application layer.

Cause 04

Too Many Attempts

Repeated retries in a short window can trigger platform-level cooldowns that delay or fully block code delivery — sometimes for hours. If this has happened, a different number is the only reliable fix.
