    Dealing with a voip number for whatsapp during registration can feel frustrating, especially when you need to connect with customers fast. WhatsApp does not always accept every voip number for whatsapp, which can block your registration. For business, customer service, and marketing, WhatsApp is huge—over 2 billion people use it, and 98% of messages get opened.

    VoIP Number for WhatsApp

    WhatsApp Policy

    You might wonder if you can use a voip number for whatsapp registration. WhatsApp does allow you to try, but there are some rules you need to know. Here’s how it works:

    1. You enter your voip number for whatsapp during registration.
    2. WhatsApp tries to send you a registration code by sms. Most voip numbers cannot receive sms, so this step often fails.
    3. If sms does not work, WhatsApp lets you choose a call option. You get a registration code by an automated voice call.
    4. Once you enter the code, your account is verified. You can now use your voip number for whatsapp messaging, calls, and even video calls.
    5. WhatsApp protects your calls with end-to-end encryption, so your chats stay private.

    Note: WhatsApp does not publish official policy changes about voip number for whatsapp registration, but these steps reflect the current process.

    Common Issues

    You may face some issues when you try to register a voip number for whatsapp. The biggest problem is not getting the registration code. Most voip numbers cannot receive sms, so you often have to wait for the call option. Sometimes, even the call does not come through. This can block your registration and leave your account stuck.

    Let’s look at some numbers:

    MetricNon-VoIP NumbersVoIP Numbers
    SMS Verification Success Rate~99%~95%
    Carrier AcceptanceHighLimited
    WhatsApp Platform AcceptanceAcceptedRejected
    WhatsApp

    WhatsApp wants you to use a number with sms or call capability. Voip numbers have lower success rates and can get flagged as security risks. If you run a business, you need a reliable way to get your registration code and keep your account active. Sobot’s WhatsApp Business API helps you handle registration, verification, and customer chats without these issues. You can learn more about Sobot’s WhatsApp solution here.

    Check Your VoIP Service

    Before you start WhatsApp registration, you should check if your VoIP provider offers real WhatsApp support. Here’s how you can do it:

    1. Make sure your VoIP number can get SMS or phone calls for WhatsApp registration.
    2. If SMS does not work, try the call option. Many virtual numbers work better with call verification.
    3. Look at your provider’s dashboard to see if messages get filtered or blocked.
    4. Check that your number is not already linked to another WhatsApp account.
    5. Keep your internet connection stable and your apps updated.
    6. Wait 24-48 hours after getting a new number before starting registration. This can help with success rates.
    7. Choose providers with high WhatsApp support rates and good reviews. Some popular options include Hushed, TextNow, and Google Voice.
    8. For business, always have a backup number and clear support steps for your team.

    Not Receiving the Code

    Are you stuck waiting for a WhatsApp registration code that never arrives? You are not alone. Many people run into this problem, especially when using a VoIP number. Sometimes, you try to receive SMS, but nothing comes through. Other times, you wait for a call, but your phone stays silent. This can block your WhatsApp verification and stop you from connecting with customers or friends. Let’s walk through some troubleshooting steps to help you get that code and finish your WhatsApp registration.

    SMS Troubleshooting

    If you are not receiving the code by SMS, don’t worry. You can troubleshoot this issue with a few simple checks. Here’s what you should do:

    • Check your network connection. Make sure your device has a strong signal and can receive SMS. Try toggling airplane mode on and off.
    • Confirm your VoIP number can receive SMS. Some numbers only support calls, not SMS. Test by sending a text from another phone.
    • Review your device settings. Go to your messaging app and check if you blocked unknown senders or enabled Do Not Disturb.
    • Make sure your WhatsApp app is up to date. An old version can cause problems with receiving the registration code.
    • Restart your device. This simple step can fix many SMS issues.
    • Look for carrier restrictions. Some VoIP providers block SMS from short codes, which WhatsApp uses for verification.
    • Wait a few minutes. Sometimes, the code takes a while to arrive. If you still do not receive SMS, try the call option.
    • Double-check the number you entered. Even one wrong digit can stop you from getting the registration code.
    • If you use a business solution like Sobot’s WhatsApp API, you get reliable verification and support. Sobot helps you avoid common SMS issues and keeps your business running smoothly.

    Tip: In the US, Puerto Rico, and Canada, some VoIP numbers have extra restrictions. Always test your number before starting WhatsApp registration.

    Call Verification

    If SMS does not work, WhatsApp lets you verify WhatsApp without a code by choosing the call option. Here’s how you can troubleshoot if you are not receiving the code by call:

    • Make sure your VoIP number can receive calls. Some numbers only support SMS.
    • Keep your phone nearby and the ringer on. You do not want to miss the automated WhatsApp call with your registration code.
    • Check your call settings. Blocked numbers or call filters can stop the WhatsApp verification call from coming through.
    • Restart your device before trying again. This can clear up temporary glitches.
    • Try using a landline if your VoIP number fails. WhatsApp can call landlines for verification.
    • If you still have trouble, use Sobot’s WhatsApp API for business. Sobot offers a seamless way to verify WhatsApp without a code, using advanced verification tools and support.

    Note: If you see a “WhatsApp verification code not received” message, wait a few minutes and try again. Too many failed attempts can lock you out for hours.

    You can always troubleshoot WhatsApp registration code issues by checking your device, network, and app settings. If you use Sobot’s WhatsApp API, you get a higher success rate for verification and can manage customer chats without delays. Sobot’s platform supports bulk messaging, chatbots, and smart routing, making it perfect for business communication. Learn more about Sobot’s WhatsApp solution here.

    How to Verify WhatsApp Number Without Code via Call

    How

    Verifying your WhatsApp account can feel tricky when you do not get the code by SMS. You might wonder how to verify WhatsApp without a code or even how to activate WhatsApp without verification code. Good news: you can request a call instead of SMS and finish the process easily. This method works for both landline and VoIP numbers, so you do not need a SIM card. Many businesses use this approach, especially when using a landline number or a VoIP service for customer contact.

    Landline and VoIP Options

    You can use either a landline or a VoIP number to verify WhatsApp without a code. When you reach the verification screen, just enter your number and choose the "Call Me" option. WhatsApp will call your number and read out the code. This is a great solution if you want to know how to get WhatsApp verification code without SIM or if your number cannot receive SMS.

    Here’s a quick comparison to help you decide which option fits your needs:

    FeatureLandlineVoIP
    Call QualityHigh-quality, reliable via provider infrastructureHigh-quality, reliable with stable Internet connection
    Cost$20-$70/user/month, extra charges for long-distance$20-$70/user/month, long-distance usually included
    ScalabilityLess scalable, costs can increase unpredictablyHighly scalable, predictable per-user costs
    ReliabilityBased on dedicated copper wire networksDependent on Internet quality and stability
    Advanced FeaturesVoice onlySupports video calls, rich messaging, voicemail transcription

    Landlines have been around for decades and offer steady call quality, even if your internet goes down. VoIP numbers give you more flexibility and features, like video calls and voicemail transcription, but you need a good internet connection. Both options work for WhatsApp verification, so you can pick what matches your business setup.

    If you want to verify WhatsApp without a code, just follow these steps:

    1. Install WhatsApp on your device.
    2. Enter your landline or VoIP number.
    3. Tap "Verify phone number."
    4. When prompted, select "Call Me."
    5. Answer the call and listen to the code.
    6. Enter the code in WhatsApp to complete verification.

    Many businesses, like those using Sobot’s WhatsApp Business API, choose VoIP for its advanced features and easy integration. Sobot helps you manage customer chats, automate responses, and keep your WhatsApp account verified without hassle. You can learn more about Sobot’s WhatsApp solution here.

    Tip: If you are using a landline number, make sure someone is available to answer the call and write down the code. For VoIP, check your call logs or voicemail if you miss the call.

    Forwarding Calls

    Sometimes, you might not be able to answer the verification call directly. Maybe you are out of the office or your phone system is busy. Call forwarding can help you never miss the WhatsApp verification code. You can set up your VoIP or landline system to forward calls to your mobile or another number. This way, you always get the code, no matter where you are.

    Businesses use call forwarding to keep customer service running smoothly. For example, a law firm reduced missed consultations by 35% by forwarding calls to the right attorney. An e-commerce startup used AI-powered call forwarding to cut customer service costs by 42%. These strategies help you answer every call, improve customer satisfaction, and keep your WhatsApp account active.

    Here’s why call forwarding matters for WhatsApp verification:

    • You can receive the code even if you are not at your desk.
    • You avoid missed calls and delays in verification.
    • You protect your privacy by hiding your personal number.
    • You keep your business running, even during outages.

    Sobot’s WhatsApp integration supports advanced call routing and forwarding. You can set up rules to make sure verification calls always reach the right person. This is perfect for teams working remotely or across different locations. Sobot also offers features like IVR and smart chat routing, so you never miss a customer inquiry or a WhatsApp verification code.

    Note: Call forwarding is not just for verification. It helps you answer customer calls faster, boost your business reputation, and keep your team connected. According to a McKinsey & Company study, call volumes have grown by 61%, and 19% more customer service leaders now focus on improving customer experience. Call forwarding is a simple way to stay ahead.

    If you want to know how to verify WhatsApp number without code via call, just remember: use the "Call Me" option, set up call forwarding if needed, and keep your number ready. Sobot makes the whole process seamless, so you can focus on growing your business and serving your customers.
