How to Register a WhatsApp Phone Number in ZazzyAgent
Most WhatsApp numbers connected through the normal ZazzyAgent onboarding process are registered automatically.
You may still see a Register Phone option in your WhatsApp settings.
This guide explains how to use it when manual registration is actually required.
Before you start
Only proceed when your WhatsApp setup requires a fresh phone registration.
This may include situations such as:
You changed the phone number.
You changed the WhatsApp display name.
You're completing a supported migration.
If your WhatsApp connection is already working and you haven't changed anything, you normally don't need to repeat registration.
Find Register Phone
Open your WhatsApp connection in ZazzyAgent.
Locate your connected WhatsApp phone number.
Open the registration option for that number.
You should see a field for: Register Number under actions
6 Digit PIN
You may also see:
Local Storage (India Only)
Enter the 6-digit PIN
Enter your WhatsApp Business Platform two-step verification PIN.
If ZazzyAgent automatically registered the number during the original connection and you have never changed the PIN, the default PIN shown by the registration workflow is:
123456
If you changed the PIN previously, use the current PIN instead.
What is this PIN?
The PIN belongs to WhatsApp's two-step verification system.
It isn't:
Your ZazzyAgent password.
Your Meta login password.
The phone-number OTP.
A temporary login code.
It is the 6-digit PIN used for WhatsApp Business Platform phone registration.
Where can I change the PIN?
The ZazzyAgent registration instructions point users to the WhatsApp Business/Meta settings for two-step verification.
You can find it through the relevant:
WhatsApp Business Manager → Settings → Two-step Verification
Meta's interface may show the setting under WhatsApp Manager and phone-number settings.
India-only Local Storage
You may see:
Local Storage (India Only)
This option is intended for Indian +91 numbers that were migrated from another WhatsApp provider.
Select it when:
Your number is:
+91
and:
The number was migrated from another WhatsApp provider.
Leave it unchecked when:
The number is new.
The number was never connected to another provider.
The number is outside India.
Do not turn this option on simply because you're using an Indian number.
Why does migration matter?
A number that has previously been connected to another WhatsApp provider can have a different migration history from a newly created WhatsApp API number.
That's why the registration workflow distinguishes migrated Indian numbers from ordinary numbers.
What happens after registration?
ZazzyAgent should complete the registration process for the connected WhatsApp phone number.
Afterward, verify that:
The WhatsApp account remains connected.
The number shows the expected status.
Messaging works.
Your display name is correct.
Your automation can receive and send messages.
Test the number
Send a test message from another WhatsApp number.
Check:
Incoming message
→ ZazzyAgent receives it
→ Automation responds
Then test an outbound message where appropriate.
Don't register repeatedly
Repeated registration is not a routine maintenance step.
The standard connection workflow handles registration automatically.
Manually registering every time you log into ZazzyAgent is unnecessary.
When registration can be useful
Registration can be relevant after configuration changes.
For example:
You changed your WhatsApp display name.
After the appropriate Meta-side change, you may need to follow the registration/synchronization instructions shown by ZazzyAgent.
The exact requirement depends on what changed.
What if registration fails?
Don't immediately change settings at random.
Check:
Correct WhatsApp number.
Correct WABA.
Current two-step verification PIN.
Whether you actually need to register again.
Whether this is a migrated +91 number.
Whether Local Storage should be enabled.
If the number was previously connected to another provider, migration status is especially important.
What if you don't know the PIN?
First determine whether the default PIN is still active.
If it was changed previously, you'll need the current WhatsApp two-step verification PIN.
Don't assume that the ZazzyAgent default value remains correct after someone has changed it.
Important distinction
There are three different things you may encounter:
OTP
Used to verify control of a phone number.
WhatsApp registration PIN
Used for the WhatsApp Business Platform registration process.
Meta password
Used to log into your Meta account.
Keep them separate.
