OTP Not Arriving? What to Check First Before Requesting Another Code

31 October 2026 · TempJar

You entered an email address, tapped “send code”, and… nothing. The instinct is to tap “resend” again and again. Resist it. Repeated resends are one of the fastest ways to turn a small delay into a locked account, because many sites limit how many codes they will send in an hour, and only the newest code works. Work through these checks in order first — most missing OTPs are explained by one of them.

1. Check the address you actually typed

This is the most common cause, and the easiest to miss. Open the sign-up page again and look at the address it shows, character by character. A single wrong letter sends the code to someone else’s inbox — or to an address that does not exist at all. Watch for autofill in particular: a browser can quietly fill in an old address, or a different handle from the one you have open in TempJar. If the address is wrong, correct it and request a fresh code; a resend to the wrong address will never arrive.

With a custom handle, also check the domain. TempJar inboxes live on its mail domains, such as jarinbox.com — typing the brand domain instead of the mail domain is a mistake that looks right at a glance and fails silently. Copy the full address from your inbox rather than retyping it from memory.

2. Wait a full minute — then check again

Email is usually fast, but “usually” is not “always”. The sending site may queue the message, a mail server may retry it, and your inbox needs a moment to pick it up. TempJar checks for new mail every minute, and an open inbox refreshes automatically, so give it at least sixty seconds before you conclude anything is wrong. If you requested a code, closed the tab, and reopened a different inbox, the code is sitting in the first one: reopen the exact handle you signed up with, using its password, rather than creating a new address and expecting the code to follow you.

3. Look beyond the inbox view

Before you blame the sender, search. Search your inbox for the sender’s name, for “verification”, and for “code” — a message can be sitting below newer mail, or filed where you did not expect it. Check any spam or filtered view your inbox offers, and remember that TempJar badges suspicious mail rather than hiding it: a message with a high spam score is still visible, so scan the whole list, not just the top item.

4. Stop hammering resend

Here is where patience pays. Most services allow only a handful of codes in a short window, and some invalidate every earlier code the moment a new one is sent. If you request five codes in two minutes, you now have five messages in flight and only the last one will work — and if you paste the first one you see, it will fail even though it “arrived”. Wait for the newest code, use that one, and if you have already hit the limit, wait out the cooldown the site states (often 15 to 60 minutes) instead of trying another address immediately, which can trigger a second limit.

5. Consider that the site may block temporary email

Some services reject disposable addresses outright. Sometimes they say so plainly; sometimes they accept the address, show a success message, and simply never send anything. If you have checked the address, waited, searched, and tried one careful resend with no result, this is a likely explanation — especially for banks, payment services, and large platforms with strict fraud controls. No inbox trick fixes it: the sender is choosing not to deliver. For those accounts, use a real address you control, or another verification method the site offers, such as an authenticator app or SMS.

That is also the line for temporary email in general: ideal for low-stakes sign-ups, trials and newsletters, the wrong tool for an account you cannot afford to lose.

6. Try a clean, second attempt

If the first attempt still has not produced a code, start clean: close the sign-up flow, wait a few minutes, then sign up once more with the exact address copied from your open TempJar inbox, and watch that inbox — and only that inbox — for the code. Ignore a code for a different service that arrives at the same time; codes are tied to the request that generated them.

Still nothing, twice over? Contact that site’s support with the time of your request and the address you used — that is something they can actually trace.

Frequently asked questions

How long should I wait for an OTP code?

At least a minute or two. Mail can be queued on the sender’s side, and TempJar checks for new mail every minute, so a code requested seconds ago may simply not have been collected yet.

Why did my OTP go to a different inbox?

Usually a typo, an autofill substitution, or a different handle than the one you have open. Compare the address the site shows with the address in your TempJar inbox, character by character, including the domain.

What if a site blocks temporary email addresses?

Then no resend will help, because the site is not sending the code at all. Use a real address you control for that service, or pick a verification method it does offer. Temporary email is for low-stakes sign-ups, not for banking or important accounts.
