4 Common Mistakes That Will Delay Your Approval

Learn from others' mistakes. Avoid these common pitfalls that cause delays or rejections:

New Domain

Submitting with a domain less than 3 months old will result in automatic rejection. Wait until your domain meets the age requirement.

Missing Opt-In

No visible consent mechanism on your website. Reviewers need to see clear checkboxes and consent language.

Unclear Purpose

Vague messaging descriptions that don't clearly define use cases. Be specific about how you'll use RCS.

🔄

Wrong Category

Misclassifying messages between promotional and transactional types. Understand the difference before applying.

✨ Best Practices for Faster Approval

  • Submit your application during business hours for faster initial review
  • Use clear, professional language in all form descriptions
  • Take screenshots of your opt-in mechanisms as proof
  • Ensure your website loads quickly and is mobile-responsive
  • Have a dedicated support email visible on your website
  • Test all forms and opt-in checkboxes before submission
  • Use SSL certificate (HTTPS) for your website
  • Keep your contact information consistent across all documents

Frequently Asked Questions

Get answers to the most common questions about RCS onboarding. Can't find what you're looking for? Contact our support team.

How long does the RCS onboarding process take?

+
The typical RCS onboarding process takes 4-5 business days from submission to approval, assuming you have all requirements in place. However, this timeline can vary:
  • If everything is perfect: 3-4 days
  • If clarifications are needed: 7-10 days
  • If major issues found: 2-4 weeks (with resubmission)
To ensure the fastest approval, make sure you meet all mandatory requirements before submitting.

Can I use RCS messaging if my domain is only 2 months old?

+
No. The 3-month domain age requirement is mandatory and non-negotiable. Applications with domains younger than 3 months will be automatically rejected. This policy exists to prevent spam and ensure legitimate businesses are using RCS.

What to do: Wait until your domain reaches the 3-month mark before applying. Use this time to perfect your website, implement opt-in mechanisms, and prepare your documentation.

Do I need separate opt-in for promotional and transactional messages?

+
Yes, it's highly recommended. While you can use a combined opt-in, having separate checkboxes provides better clarity for users and stronger compliance protection:
  • Promotional opt-in: "I want to receive marketing messages, special offers, and promotions"
  • Transactional opt-in: "I want to receive order updates, OTP codes, and service notifications"
This approach gives users more control and shows reviewers you understand message categorization.

What happens if my application is rejected?

+
If your application is rejected, you'll receive detailed feedback explaining the reasons. Common rejection reasons include:
  • Domain age below 3 months
  • Missing or unclear opt-in mechanisms
  • Incomplete privacy policy or terms & conditions
  • Website not accessible during review
Next steps: Address all issues mentioned in the feedback, make necessary changes to your website, and resubmit your application. There's no penalty for resubmitting.

Can I test RCS messages before full approval?

+
It depends on your RCS provider. Some platforms offer sandbox environments for testing, but full RCS messaging to real user devices requires complete onboarding approval. During the testing phase:
  • You may be able to send test messages to verified numbers
  • Message throughput will be limited
  • Some features may be restricted
Contact your RCS Business Messaging provider for specific testing capabilities available before full approval.

Do I need a privacy policy specifically for RCS messaging?

+
Your existing privacy policy should be updated to include how you handle RCS messaging data. Key sections to include:
  • What types of messages you'll send via RCS
  • How you collect and store phone numbers
  • How users can opt-out of RCS messages
  • Data retention policies for messaging data
  • Third-party sharing (if applicable)
A generic privacy policy without mention of messaging practices may not pass review.

Can I change my use case after approval?

+
Minor changes to messaging content within your approved category are usually fine. However, major changes require resubmission:
  • No resubmission needed: Updating message templates, adjusting timing, refining content
  • Resubmission required: Changing from promotional to transactional, adding new message categories, significantly expanding use cases
When in doubt, consult with your RCS provider before making major changes to avoid compliance issues.

What if my website is temporarily down during review?

+
This will likely result in rejection. Reviewers need to verify that your website is live and accessible. If your site is down during the review window:
  • Your application will be flagged for non-compliance
  • You'll likely receive a rejection notice
  • You'll need to resubmit once the site is stable
Best practice: Ensure your website is stable before applying. Delay your submission if you have planned maintenance or expect technical issues.
