How to Fix WhatsApp Verification Code Not Received

In this article, we’ll explore all the reasons why WhatsApp verification codes fail, how to fix it step by step, and how tools e.g.: AdsPower, can make multi-account login and verification easier for advanced users.

Why WhatsApp Sends Verification Codes (And Why They Sometimes Fail)

When you sign up or log in to WhatsApp, the platform sends a 6-digit verification code to the phone number you entered. This is a core security measure that confirms ownership of the number. Without this code, you can't access your account — even if it's your number.

But sometimes, the code never shows up. Why?

Common reasons include:

● Incorrect phone number or country code

● Network or SIM card issues

● WhatsApp’s internal rate limits (after too many requests)

● Blocked SMS or calls from WhatsApp

● Do Not Disturb (DND) settings or call-blocking apps

● Issues with dual-SIM phones or inactive lines

● VPN or proxy interference

Understanding what’s causing the delay or failure is key to applying the right fix.

Why You're Not Receiving the WhatsApp Code

Let’s dig deeper into the most likely culprits:

1. Incorrect Phone Number Format

A simple mistake like entering the wrong country code or misplacing a digit can send the code elsewhere. Always use the international format (e.g., +1 for the U.S., +84 for Vietnam).

2. SIM Card Not Inserted or Active

If your SIM is not inserted, turned off, expired, or inactive (e.g., roaming outside its country of service), WhatsApp can’t send the code to it.

3. Network & Signal Issues

Low signal strength or unstable networks can block incoming messages or delay calls. This is common in elevators, underground areas, or rural zones.

4. Do Not Disturb / Battery Saver / Focus Modes

Modern smartphones often block unknown SMS or calls while in DND or battery-saving modes.

5. You’ve Tried Too Many Times

If you requested the code multiple times within a short period, WhatsApp may throttle your number. This is a spam-prevention measure.

6. WhatsApp Code Blocked by Carrier or App

Some carriers or apps (e.g., spam filters or message blockers) may prevent WhatsApp codes from reaching you.

How to Get WhatsApp Verification Code by SMS (Step-by-Step Fixes)

Here's how to fix the problem depending on your situation:

Step 1: Confirm You Entered the Correct Number

Double-check your number, including the country code. Example:

● ✅ Correct: +1 555-123-4567

● ❌ Incorrect: 015551234567 (without country code)

Step 2: Switch to a Stronger Network

If you're in a low-signal area, move to a space with better signal or temporarily switch from Wi-Fi to mobile data (or vice versa).

Step 3: Restart Your Phone

This resets your network modules, SIM recognition, and refreshes background services like messaging.

Step 4: Temporarily Disable VPN or Wi-Fi Calling

VPNs, firewalls, or Wi-Fi calling features can interfere with SMS or call delivery. Disable them during the verification process.

Step 5: Request a Voice Call

If you don't receive the SMS within 1 minute, WhatsApp will allow you to choose the "Call me" option. The automated call will dictate the 6-digit code.

Step 6: Remove Extra SIM Cards

If you have a dual SIM phone, remove or disable the secondary SIM temporarily. It may cause routing conflicts or confuse WhatsApp.

Step 7: Check for Blocking Apps

Disable any spam-blockers, call filters, or security apps that may be silently blocking messages or calls.

Step 8: Try Again After a Cooldown Period

If you've attempted too many times, wait at least 1 hour before trying again. Do not use third-party SMS services to rush the process — WhatsApp may flag that as suspicious.

Can I Receive a WhatsApp Verification Code via Email?

No. WhatsApp does not and will not send your verification code via email — for security and privacy reasons.

If you receive any email claiming to offer a WhatsApp code or asking for your code, it’s a scam. Only trust the official WhatsApp app and phone number verification screen.

WhatsApp supports only two methods:

● SMS (text message)

● Voice call (automated)

Multi-Account & Business Users: Reducing Verification Hassles

If you’re managing multiple WhatsApp accounts (e.g., for customer support, eCommerce, or marketing), frequent verification requests can become a nightmare. WhatsApp may throttle SMS delivery, temporarily ban accounts, or even flag unusual IPs.

This is where AdsPower becomes a game-changer.

How AdsPower Helps with WhatsApp Multi-Account Management

AdsPower is an anti-fingerprint browser designed for safe, scalable multi-account workflows. It allows you to create virtual browser profiles, each with its own unique IP address, user agent, and environment — helping you log in to multiple WhatsApp Web or mobile instances without getting flagged.

Key benefits for WhatsApp users:

● Separate browser profile for each WhatsApp number

● Proxy integration to simulate different locations/devices

● Cookie & session storage to reduce repeated verification prompts

● Fewer verification failures due to clean, isolated environments

● Works well with WhatsApp Business Web or WhatsApp Cloud API integrations

For digital agencies, crypto communities, or remote customer service teams, AdsPower anti-detect browser helps manage up to hundreds of accounts securely — while avoiding annoying SMS verification delays or bans.

Prevent Future Verification Code Problems

Here’s how to avoid being stuck again the next time you reinstall WhatsApp or change devices:

1. Keep Your Number Active

Don’t let your SIM card expire, especially if it’s from a virtual provider or prepaid plan.

2. Add a Backup Number (if using Business API)

Businesses using WhatsApp Business API can register backup admins to prevent lockouts.

3. Don’t Reinstall the App Too Often

Reinstalling frequently triggers verification checks. Use session preservation features (e.g., AdsPower cookies) to keep your login.

4. Avoid Rapid Logins from Multiple Devices

Jumping between devices too often can raise flags on WhatsApp servers.

5. Use Tools Like AdsPower for Multi-Profiles

Instead of juggling incognito tabs, simulate unique environments per account. This reduces rate-limiting and avoids "feedback_required" or "code not sent" errors.

6. Avoid Grey-area Methods

Don’t buy virtual numbers or shared SIMs. WhatsApp has strong detection methods that can result in permanent bans.

FAQ

Can I Open My WhatsApp on Another Phone Without a Verification Code?

No. WhatsApp requires the 6-digit code to log in on a new device. The only exception is when you use Linked Devices while already logged in — this allows desktop/multi-device usage without re-verifying every time.

If you're completely locked out, and can’t receive the code, your only option is to restore access to your SIM or request the voice call feature.

How To Check If Your Phone Number Is Blocked By WhatsApp?

If you’re blocked by WhatsApp:

● You’ll see a message: "Your phone number is banned from using WhatsApp."

● You won’t receive the code at all — not even voice calls.

● Attempts to log in will result in rejection.

WhatsApp typically bans numbers for violating Terms of Service, including:

● Using unauthorized apps

● Spamming

● Bulk messaging

● Using multiple sessions without proper safeguards

Conclusion

Not receiving your WhatsApp verification code can be a frustrating experience — but it’s rarely permanent. For personal users, a few simple fixes like restarting your device, checking your number, and requesting a voice call usually do the trick.

For business and power users, especially those managing multiple accounts, it’s worth investing in tools like AdsPower to maintain security, stability, and scale. With virtual browser environments and advanced fingerprinting, AdsPower minimizes verification disruptions and lets you focus on what matters — running your operations smoothly.

If you’re stuck, don’t panic. Just follow the steps, stay patient, and avoid violating WhatsApp’s account policies.
