"Too Many Attempts" / Rate-Limited on Verification — What to Do

By The CODASMS TeamUpdated July 10, 2026
Quick answer: "Too many attempts" means the platform has temporarily rate-limited your verification requests to prevent abuse. The fix is to stop, wait out the cooldown, and then verify once with a clean, correct number — rather than hammering the request button, which extends the lockout.

Why you're rate-limited

Platforms cap how many verification codes you can request in a short window. It's an anti-abuse measure: rapid repeated requests look like an automated attack, so the platform makes you wait. If you've been re-requesting a code because the first didn't arrive — often because the number was VoIP or recycled and silently rejected — you can hit this wall quickly.

What to do

  1. Stop requesting. Each new attempt during a cooldown can extend it. Step back.
  2. Wait out the window. Cooldowns are timed — usually minutes, sometimes up to an hour on stricter platforms. Wait before trying again.
  3. Fix the underlying number. If you were rate-limited chasing a code that never came, the number was likely rejected. Switch to a fresh, carrier-grade, country-matched number so the next attempt succeeds in one go.
  4. Verify once, cleanly. With the right number, a single request delivers the code — no repeated attempts to trip the limit.
The loop to avoid. Bad number → no code → re-request → rate-limited → still no code. Break it by fixing the number, not by requesting harder.
How carrier lookup decides CARRIER LOOKUP You enter a number the platform queries carrier API Twilio · Telesign · IPQualityScore VoIP detected Real carrier SIM REJECTED Free VoIP / recycled pool numbers Code is never dispatched ACCEPTED Code is delivered Account verifies first try The check happens before the code is ever sent. A rejected number never receives an SMS.
Before the platform sends a code, it queries a carrier-lookup API to classify the number. VoIP ranges are refused silently — the SMS is never dispatched. "The code never arrived" usually means the number was rejected, not delayed.

How long is the lockout?

Most cooldowns clear within a few minutes; stricter platforms can hold you for up to an hour. The timer usually resets if you keep requesting, so the fastest route out is to wait quietly, then verify once with a number that will actually work.

Why pay-per-code helps

A carrier-grade number that delivers on the first request means you rarely trip the limit at all — and if a number is flagged, you're refunded and can try another without racking up failed attempts.

Frequently asked questions

What does 'too many attempts' mean?

The platform has temporarily rate-limited your verification requests as an anti-abuse measure. It's a timed lockout, not a permanent block.

How long does the cooldown last?

Usually a few minutes, though stricter platforms can hold you up to an hour. Requesting again can extend it.

Why did I get rate-limited?

Often from re-requesting a code that never arrived — typically because the number was VoIP or recycled and silently rejected.

How do I avoid it next time?

Use a clean, carrier-grade, country-matched number so a single request delivers the code without repeated attempts.

What if I still can't get a code after the cooldown?

Switch to a fresh number and try once. You only pay when a code is delivered.
