Why Is PayStack Failing to Verify My Business CAC Number?

Below are some troubleshooting steps and suggestions that may help resolve the CAC verification issue with PayStack:

1. Double-Check Input Formatting

Ensure that the CAC number is being entered exactly in the format that PayStack expects. Consider the following:

• Remove any extra spaces, special characters, or prefixes/suffixes that might have been added inadvertently.
• If there are multiple acceptable formats (e.g., IT, RN, RC, BN), try using the one that is most commonly accepted by PayStack.

2. Validate Against Known Formats

Sometimes service providers require the CAC number to have a specific prefix or pattern. Even though the CAC site confirms its validity, PayStack may require a standardized format. You might want to:

• Compare your number with examples provided in any official PayStack documentation or FAQs.
• Try alternative known formats (if you haven’t already) to see if one is accepted.

3. Clear Cache and Use Supported Browser

Occasionally, stale data in your browser cache might cause issues:

• Clear your browser’s cache.
• Try the process with a different browser or in incognito/private mode to rule out client-side issues.

4. Contact PayStack Support

If the above steps don’t resolve the problem, it’s best to get in touch with PayStack support. Provide them with:

• A detailed description of the error.
• The exact format you used for the CAC number.
• Screenshots of the error message and a confirmation from the CAC site (if possible).

PayStack support should be able to look into your verification process, check if the right endpoints are being called, or if there’s a backend issue on their end.

5. Check for System or API Updates

If you’re integrating via an API:

• Make sure you are using the latest API version and refer to the updated documentation.
• Check if there are any recent announcements or known issues related to business number verification that might affect your integration.

Following these steps should help identify whether the issue is due to formatting, browser-related, or a backend verification process. If everything appears correct, reaching out to PayStack support with detailed information is the best way to get a resolution.
