Phone Number Verification in WHMCS

[benstechtips]

Hi,

 

I am trying to configure WHMCS to register domain names with the NameCheap API. The API setup works correctly, however I cannot register domain names unless the client provides the country code with their phone number (e.g. the client would need to set 441234567890 instead of 01234567890).

 

If the client types their phone number without the country code, registration with namecheap fails. If the client types the phone number with the country code, registration is successful.

 

Is there a way in WHMCS to set a validation on the phone number field to ensure the country code is entered? Or at least a way of putting a note next to the phone number label?

 

Thanks
