How do we ensure phone number formatting for SMSs?

How do we ensure phone number formatting for SMSs?

Hi Everyone,

I have question regarding formatting of phone numbers to be used with the third party app integration for sending SMS.

I have never used any SMS messaging automation in the past and numbers need to be sent in the E.164 format which starts with a +[country code][area code][number] to give us something that looks like this +50612345678. My question is, how do I ensure compliance from my potential lead when they are filling out a web form? 

I ask because it seems that the standard phone fields in MarketingHub are not set up to collect country codes as some other Zoho apps do or perhaps I am missing something.

Can anyone help me with this?

Regards,
