The Email Verification Code Generator for Testing.

No. Every email verification code this generator produces is random and fake, synthetic sample data meant for testing signup, OTP, and 2FA flows. A code is not tied to any real account, email, or session, and it will not log anyone in or confirm anything anywhere.

That is the whole point of the tool: a believable one-time code you can paste into an “enter the verification code” field or a test fixture without waiting on a real email. When you need to confirm a real address can actually receive the message that carries a code, that is a different job, handled by the free email checker.

An email verification code is a short, single-use string, most often a 6-digit number like 482915, that an app emails you to prove you control an inbox. You enter the code on screen, the app matches it, and the email verification step is complete. It is the same idea as a one-time passcode (OTP) used in two-factor authentication.

This page does not send any email. It generates the codes themselves, the kind of value that would arrive in an email verification message, so you can use them as realistic test data while building or QA-ing the flow that consumes them.

Use the generator at the top of this page. Pick how many codes you want, one or up to twenty-five, choose a length of four, six, or eight characters, pick numeric or alphanumeric, and select Generate. The batch appears instantly.

From there you can copy a single code, copy the whole list, or download it as a .txt file. It all runs in your browser, so you can regenerate a fresh batch as many times as you like with no signup.

Most products use a 6-digit numeric code, which is the familiar OTP length and easy to read off a phone. Four digits are common for low-risk confirmations, and eight characters, especially alphanumeric, raise the entropy when you want a code that is harder to guess or brute-force.

The generator covers four, six, and eight characters in numeric or alphanumeric, so you can mirror whatever your real flow issues. For readability the alphanumeric set skips look-alike characters such as O, 0, I, and 1, the same convention real code systems use.

Yes, and it is the main use. A random verification code lets you fill the “enter the code we emailed you” field with realistic values so you can test the happy path, expiry handling, retry limits, and the error state for a wrong code, all without standing up a real mail server first.

One thing to keep in mind: because the code is generated here and not by your app, it will only match if your test harness treats it as the expected value. For an end-to-end test where the app generates and emails the real code, you need a test inbox to read it from. To confirm the address in that flow can receive mail at all, pair it with real-time verification.

When a signup says email verification required, the app wants proof you own the address before it activates the account. It emails a verification message containing a code or a link; entering the code (or clicking the link) clears the requirement. It cuts down on typos, throwaway addresses, and fake accounts.

The code on this page stands in for the one inside that email verification message, so you can build and test the screen that asks for it. If you are deciding whether an address should even be allowed to reach the verification step, screen it first with the free email checker.

Yes. Set the count to generate up to 25 random codes at once, then copy them all or export the list as a .txt to drop straight into a test fixture, a seed script, or a spreadsheet of test cases.

If you need thousands of codes programmatically, generating them in code (for example with your language’s secure-random library) is the better fit. This tool is built for quick, copy-and-go batches you need right now. And if the same fixture needs fake corporate addresses to pair with the codes, the random work email generator produces those in matching batches.

Yes. Generation happens entirely in your browser using the platform’s cryptographic random source, with no signup and no API call, so nothing you generate is sent to a server or logged. The codes are random strings, not linked to any person or account.

No. This tool does not send any email and cannot deliver a code to your inbox, it only produces sample codes for testing. If you are waiting on a real code from a service, check your spam folder, request a resend, and confirm you typed the right address.

A common reason a real verification message never arrives is that the address itself is invalid, full, or unable to receive mail. You can check whether an address can accept a verification email with the free email checker, probe the receiving mail server directly with the SMTP test, or test your own sending setup end to end with the verification engine.

Generating codes here is a free, client-side tool, so there is no code- generation API to call, you can produce as many batches as you like right on this page. Email verification, though, is a real product: the REST API reference documents the endpoints for checking whether an address is valid and can receive a verification message, which you can wire into your signup, your CRM, or any tool that speaks REST.

Verifox also ships native MCP server support so AI agents (Claude, Cursor, custom LLM apps) can verify addresses without glue code, with pay-as-you-go pricing localized to your region on the pricing page. Live uptime is at status.verifox.ai.
