Unlike Instagram or Facebook, WhatsApp doesn’t ask users to share email IDs. The Facebook-owned service solely relies on the mobile number to verify user identity. When you switch from one device to another, WhatsApp will ask for verification via SMS or call to let you access the account. That’s beside the two-step verification for WhatsApp you may have set up. If you don’t get the required security code from the company?
WhatsApp won’t load your messages or let you access conversations without a security code. When WhatsApp is not sending a verification code, it can leave you confused. Whether it is your personal or business account is tied with your mobile number, you have no option but to enter the right security code. Let’s start the troubleshooting journey.
When you open WhatsApp, the app automatically detects your region and shows a dialling code and a menu to enter your mobile number. Make sure to type the correct mobile number to get a security code. Before you proceed further, WhatsApp will ask you to check your entered number again. At any time, you can hit the Edit button to fix typos.
If you are not receiving a verification code from WhatsApp, you can force close the app and try again.
Step 1: Open the Recents apps or multitasking menu on iPhone or Android.
Step 2: Swipe up on the WhatsApp card to close the app.
Step 3: Launch WhatsApp, enter your mobile number and try again.
You may not receive the latest messages when you deal with a patchy network connections at home or office. Make sure to have at least two or three network bars on your phone to receive text messages without any problem. You can temporarily enable Airplane mode on your phone and disable it to reset the network connection.
Step 1: Swipe down from the top right corner (iPhone users with a home button can swipe up from the bottom) to open the Control Center menu.
Step 2: Enable the Airplane mode toggle and disable it after some time.
Step 1: Swipe down from the top to open the quick toggles menu.
Step 2: Enable Airplane mode and turn it off after a few seconds.
Return to the WhatsApp and try to regenerate the security code. You can also reset network settings on your phone if the issue persists. The option won’t delete any personal files or installed apps on your phone.
Your local carrier might suspend your account if you have an unpaid bill or charges. You must clear dues with your carrier to resume services. Once you get back to an active carrier plan, repeat the second step and get a WhatsApp security code without any issue.
When your local carrier or WhatsApp servers faces issues, you might notice a delay in receiving a text message from WhatsApp. You can head to Downdetector.
com and search for your carrier and WhatsApp. You can look for recent high outage graphs or check user comments to confirm the issue.
The default iOS and Android Messages app can be aggressive and send necessary relevant to the spam folder. Here’s how you can access spam messages on iPhone and Android.
Step 1: Open Messages on iPhone.
Step 2: Select Filters in the top left corner.
Step 3: Select Junk inbox.
Step 1: Launch Messages on iPhone.
Step 2: Tap on the three-dot menu in the top right corner.
Step 3: Open the’ Spam and blocked’ inbox.
If you still face an issue with not getting a WhatsApp security code, you can confirm your identity with a missed call. WhatsApp will give a miss call on your mobile number and check call logs to verify your identity.
Step 1: Open WhatsApp, enter your mobile number, and hit the Next button.
Step 2: Hit Continue to verify your number.
WhatsApp may ask for permission to access call logs.
Due to an outdated WhatsApp app built on iPhone and Android, you might face issues getting a security code. You can head to Google Play Store or Apple App Store and install pending WhatsApp updates on your phone.
WhatsApp not sending a security code can get troublesome for those who rely on the app to communicate with friends, family, and clients. Use the tricks above and fix the issue in no time. Meanwhile, you can temporarily switch to Telegram or Signal to stay in touch.

SMS one-time passcodes (OTPs) are a popular form of phone verification and two factor authentication (2FA), but in some countries like Brasil, Germany, or India, messaging apps like WhatsApp are more popular than SMS.
That's why we added support for WhatsApp in our Verify API. Since WhatsApp does its own phone number verification at sign up, you can use WhatsApp verification to directly replace SMS verification. Best of all, by using WhatsApp through the Verify API, you do not need a separate WhatsApp Business Account.
This blog post will show you how to quickly spin up an OTP dashboard and start sending and checking WhatsApp verification messages.
Before you can send an OTP you'll need:
Copy your Service SID (starts with VA):
Make sure you're logged in to Twilio and head over to Twilio's Code Exchange for the One-Time Passcode verification project and paste in your Verify Service SID:
Next, click "Deploy my application".
After a few seconds you should see a button to launch the live application: click that to go to your new Verify application.
Select the WhatsApp channel, enter your phone number and hit Get a one-time passcode to test it out. It's really that easy!
One way to improve user experience is to default to WhatsApp instead of SMS when it's available. You can check if the app is installed on the same device you're running on. Follow the instructions for iOS and Android to determine if a package is installed. Here's an example WhatsApp detection implementation for Android:
fun PackageManager.isPackageInstalled(packageName: String): Boolean { return try { getPackageInfo(packageName, PackageManager.GET_ACTIVITIES) true } catch (e: NameNotFoundException) { false } } fun isWhatsAppInstalled : Boolean() { val whatsAppPackageName = "com.whatsapp" val whatsAppBusinessPackageName = "com.
whatsapp.w4b" return getPackageManager().isPackageInstalled(whatsAppPackageName) || getPackageManager().isPackageInstalled(whatsAppBusinessPackageName) } Unfortunately not every user has a WhatsApp account. While you can detect whether the WhatsApp application is installed on mobile, WhatsApp does not have an API to determine if an account exists prior to sending a message. Fortunately, WhatsApp does not charge for failed message attempts to accounts that don't exist while SMS does charge carrier fees for undelivered messages.
This application doesn't actually protect anything (yet!), but if you're like me, you love having code to copy and modify. This application gives you the following building blocks:
You can use this as a basis to send and check verifications in your own application for sign up, login, or step up authentication like at checkout.
The email channel requires a smidge more setup but all of the instructions are outlined in the documentation. While you're testing, you might be interested in spinning up a testing dashboard to help avoid hitting rate limits.

Despite the fact that no one limited the work of WhatsApp in Russia , after blocking Instagram and Facebook, the messenger increasingly began to experience problems with authorization.
Users complain that they cannot log into their account because WhatsApp does not send a message with the verification code . He writes like this: failed to send SMS to the number you specified . Why is unclear. After all, this happens today almost every second, and only a few manage to find the cause of the failure, and even more so to eliminate it. It's good that you have us and we know what to do in such situations.

WhatsApp authorization failure usually occurs when you try to log into your account for the first time on a new device.
The user enters his phone number for verification, but the smartphone - and, judging by the reviews, this happens regardless of the platform used - gives an error, thus explaining why does not receive SMS from WhatsApp .

No, of course, WhatsApp does not leave you completely without explanation and further instructions. The messenger writes that in an hour it will be possible to try again. However, as my personal experience has shown, if you encounter a failure, then not in an hour, not in two, or even the next day, the problem will not disappear, and Vatsap will not send you SMS with authorization code .
There are several ways to solve the problem with authorization in WhatsApp
WhatsApp developers know that messenger users regularly experience similar problems, so we have prepared several recommendations in advance that you need to follow if you do not receive a code from SMS from WhatsApp :

Make sure you don't make a mistake in the number, enter the correct country code, because WhatsApp often substitutes the +1 code instead of +7, as it is necessary for Russia. 
However, if the above recommendations do not help, this does not mean that the solutions to the problem have been exhausted. Actually it is not. There are at least two options that will help you in most cases enter WhatsApp on iPhone . And, if you have Android, and you cannot log in to WhatsApp, read this article - everything is there.

First of all, try turning on the VPN.
Strange thing: WhatsApp in Russia is not restricted by anyone, but for some unknown reason, SMS with authorization codes may not reach users if they are in the country. In such cases, it is better to use the lock bypass service. For example, I use Planet VPN.
Install VPN. He will probably decide everything
Download Planet VPN
It doesn't matter which VPN you choose . If you need a free service, Planet VPN will do just fine. You do not need to pay anything for it, and it is also completely unlimited, although it cuts the download speed. But after all for authorization it does not play any role. However, if you don't trust this service or have your own in mind, use it.
does not arrive Few people pay attention to this, at the authorization stage WhatsApp allows not only to confirm the entry by SMS , but also by call. In this case, the bot will call you and dictate the authorization code aloud. It is a one-time use, so it does not make sense to write it down for all subsequent logins, as it will not be applicable.
For the life of me, I couldn't provoke this bug on iOS
If you've already signed in to WhatsApp on your iPhone before and saved your credentials to Keychain Access, you may not need to enter the code again. Then authorization will take place automatically, without requiring additional verification. 
Important clarification: the button to confirm the entry by call may not appear immediately after the first launch of the application. Therefore, it is recommended that you first request the WhatsApp authorization code by SMS . Only then, if the message does not arrive within five minutes, you will have the opportunity to use an alternative login method.
