How Long to Wait Before Requesting Another SMS Code

Give a code a full minute or two, then request one resend, and do not go past two or three requests an hour. Most one-time codes arrive within 5 to 30 seconds. Past that, pressing the button more often usually makes things worse, because many services slow down or pause a number that asks too often.

Updated November 2026. Services do not publish their exact limits, so these are rules of thumb. Check the service's own help page.

Why waiting helps

When you ask for a code, the service creates it, logs the request and often starts a countdown on your number. Each new request tends to do one of two things:

• It cancels the older code. The newest code is the only one that works. If you asked four times in a minute, an older text can arrive after a newer one, and you type the dead one.
• It counts toward a limit. Some services allow a resend every 30 seconds, some every two minutes, some only a few an hour. Many put roughly three to five sends an hour on one number, but the real figure depends on the service and country.

A retry timeline that usually works

Assuming a decent signal:

• 0:00 Request the code. Check your messages, including filtered or unknown-sender folders.
• 0:30 Do not resend yet. Check airplane mode and that you are not on Wi-Fi only if the app needs a mobile connection.
• 1:00 to 2:00 Request one resend. Note the time.
• 3:00 Check the inbox again, sorted by time so a new message is not buried.
• 5:00 If the service allows it, a second resend is reasonable.
• After two or three attempts over about twenty minutes, stop. Change something other than the button: the number, the way the code is sent (a call instead of a text), or the device.

If you see "too many requests" or a cooldown

This is a limit on that number, often with your device or network as well. It is usually not a ban, and it ends by itself.

1. Stop tapping. Every tap can restart the timer.
2. Let the countdown reach zero once before you try.
3. Wait longer if there is no countdown. A soft block can run from a few hours to about a day, depending on the service.
4. Make one clean attempt afterwards: good signal, filters off, ready to read the message straight away.

If no attempt works

Then the number or the route is the problem, not your timing. Check the causes in why verification codes do not arrive, and test the number with how to tell if a number can receive verification codes. If the number cannot receive them, you need another number. A real US mobile line from our services page is one way to get one. For services that call, voice verification answers for you. We cannot guarantee any service accepts a number. If the code does not arrive, you get a full refund (pricing).

What happens to a number after you get the code

A one-time number is gone within minutes, and cannot receive another code. If you might need the number again, for example for a re-verification, rent it instead. Rentals run from one day to one year (rentals), then the number returns to the pool. For an account you want to keep, use your own number and add a recovery email.

Frequently asked questions

How long should I wait before pressing resend?

At least one to two minutes, unless the app shows a timer. Use that timer.

Does pressing resend again cancel my first code?

Often yes. Use the newest code.

Why did the code arrive late?

Signal gaps, carrier delays and filters can hold a text for minutes. Many codes expire in a minute or two.

How many times can I request a code?

It varies. Two or three an hour is a safe rule of thumb.
