How to Register a WhatsApp Number with Twilio (Step-by-Step Guide)

Learn how to register your WhatsApp Business number with Twilio in 7 steps. Covers prerequisites, registration, and Meta Business Verification.

Want to send and receive WhatsApp messages through Twilio? You’ll first need to register a WhatsApp-enabled phone number in the Twilio Console. This guide walks you through every step — from prerequisites to going live.

Prerequisites

Before you start, make sure you have the following ready:

  • ✅ An upgraded Twilio account with a linked payment method (upgrade via Admin → Account billing → Upgrade account)
  • ✅ A WhatsApp-compatible phone number — either a Twilio number or your own
  • ✅ A Meta Business Portfolio with administrator access and full permissions
  • ✅ A Facebook account linked to your Meta Business Portfolio

Phone Number Requirements

Your phone number must meet these requirements:

  • It must satisfy WhatsApp’s compatibility requirements
  • It must not already be registered with WhatsApp (personal or business)
  • Non-Twilio numbers must be able to receive SMS or voice calls for OTP verification
  • Numbers behind an IVR system cannot receive OTPs and won’t work

Tip: If your company already has a Meta Business Portfolio, request administrator access with full permissions — this is required to create a WhatsApp Business Account (WABA) during sign-up. If you don’t have one, you can create it during the process, but you’ll need to complete Meta Business Verification before moving into production.

The 7-Step Registration Process

Step 1: Access WhatsApp Senders

  1. Log into your Twilio Console
  2. Navigate to Messaging → Senders → WhatsApp Senders
  3. Click Create new sender

Step 2: Select Your Number

  1. Under “Select a phone number to register,” choose either a Twilio phone number or a Non-Twilio phone number
  2. If using your own number, enter it in the field
  3. Click Continue

Step 3: Connect to Facebook

  1. Under “Link WhatsApp Business Account with your number,” click Continue with Facebook
  2. A Self Sign-up pop-up window will open on facebook.com

⚠️ Critical warnings:

  • Do not close either the Facebook pop-up or the Twilio Console window
  • Do not share the pop-up window URL with anyone — the registration will fail
  • Complete all steps in the same browser so Meta and Twilio can exchange data properly
  1. Log into Facebook or continue with your existing session
  2. Allow Twilio to manage your WhatsApp Business Account

Step 4: Configure Business Details

  1. Select your Meta Business Portfolio (or create a new one)
  2. Create or select your WhatsApp Business Account (WABA)
  3. Create a new WhatsApp Business profile

Important WABA rules:

  • First sender? Create a new WABA — don’t select one created outside of Twilio (e.g., with another provider)
  • Additional senders? You must select the same WABA used for your first sender
  • Twilio maintains a one-to-one relationship between a Twilio account and a WABA — you can’t use multiple WABAs in one account

Step 5: Enter Business Information

Fill in the required and optional fields:

FieldRequiredNotes
WhatsApp Business Account Name✅Internal use only
WhatsApp Business Display Name✅What your customers see — must match your Meta Business Portfolio name
Category✅Describes your business type
Business Description❌Optional but recommended
Website❌Optional but recommended

⚠️ Display Name Warning: Meta reviews your display name after registration. If they reject it, your number is limited to 250 business-initiated messages per 24 hours, and Meta may disconnect the sender entirely. Always use your actual company name and follow Meta’s display name guidelines.

Step 6: Verify Your Phone Number

For Twilio numbers:

  1. Switch back to the Twilio Console window
  2. Copy the verification code displayed
  3. Paste it into the Facebook pop-up window
  4. Click Next

For non-Twilio numbers:

  1. Enter your number in the Facebook window
  2. Select verification method — SMS or Voice call
  3. Receive and enter the verification code

Step 7: Complete Registration

  1. Review and confirm Twilio’s access request
  2. The pop-up window closes automatically
  3. Twilio starts the registration process — this might take a few minutes
  4. The Console automatically refreshes to show your registered sender

✅ Your registered number will now appear in WhatsApp Senders! You can click Edit Sender to:

  • Set your inbound message webhooks
  • Update your WhatsApp Business profile and profile picture
  • Add the sender to a Messaging Service
  • Manage or delete the sender

Post-Registration: Meta Business Verification

You can start messaging immediately after registration. However, to scale in production and increase messaging limits, you’ll need to complete Meta Business Verification.

Note: Business verification is free and is not the same as Meta’s paid “Meta Verified” subscription.

How to Get Verified

  1. Follow the steps in How to verify your business on Meta
  2. Check your status in Meta’s Security Center
  3. Upload required business documents — accepted types include:
    • Certificate or Articles of Incorporation
    • Business registration or license document
    • Government-issued business tax documents (self-filed documents not accepted)
    • Business bank statements
    • Utility bills (for address and phone verification only, not legal name verification)
  4. Processing time varies by region and can take several weeks — start early to avoid delays

Without Verification, You’re Limited To:

WhatsApp senders per Twilio account2
Business-initiated conversations per 24 hours250

With Verification, You Unlock:

  • Higher messaging limits — starting at 1,000 templates/day, scaling up to 100,000/day for verified businesses with good quality ratings (as of Q1/Q2 2026)
  • Portfolio-based limits — since October 2025, messaging limits apply to your entire business portfolio, not per phone number, so new numbers immediately access your highest tier
  • More than 2 WhatsApp senders per account
  • Eligibility to request a WhatsApp Official Business Account (OBA) with the green checkmark badge

Key Warnings to Remember

  • 🚫 Use your company name as the display name — WhatsApp rejects names that don’t match your Meta Business Portfolio, and rejected names limit you to 250 messages/day
  • 🔒 Complete all steps in the same browser session — don’t copy URLs or share the pop-up link with other users
  • 📱 All WhatsApp Senders in a Twilio account must be in the same WABA — don’t reuse a WABA from another provider
  • ⏳ Without Meta verification, you’re limited to 2 senders and 250 conversations / 24 hours
  • 📵 US marketing pause — as of April 2025, marketing template messages to US phone numbers (+1) are paused by Meta
  • 💰 New pricing model — as of July 2025, WhatsApp uses per-message pricing instead of per-conversation billing
