WhatsApp Business API onboarding for UK businesses: a practical guide

What UK teams need before they apply, how verification works, and how to send your first template message without delays.

Why onboarding stalls

Most delays in WhatsApp Business API onboarding come from incomplete business verification details rather than the technical setup. Getting your documentation in order first keeps the process to days rather than weeks.

What you need before you start

  • A registered UK business with matching public details.
  • A phone number that is not already active on the WhatsApp consumer app.
  • A verified Facebook Business Manager account.
  • A clear opt-in route for the customers you intend to message.

Business verification

Verification confirms that your business is who it says it is. Keep your company name, address and website consistent across Companies House, your website footer and your Business Manager profile.

Your first message template

Template messages are pre-approved formats used to start conversations outside the 24-hour customer service window. Write them as clear, specific notifications rather than marketing copy and they will usually be approved quickly.

Next steps

Once your number is connected you can move on to bulk messaging and integrations with your existing systems.
