Login with Apple ID vs mobile phone required

Hi everyone,

Background: 

  1. We want to provide our customers with login with Facebook option
  2. It means - according to Apple policy - we must also implement login with Apple ID, and we are fine with it
  3. But - because of type of our business - we must collect from our customers also their mobile number.

 

  • First of all, it's their unique ID in our system (but of course we could change it, if it was necessary).

  • But - what's more important - we are two-sided marketplace, we connect customers (pet parents) with business (vets, groomers, behaviourists, pet sitters etc.). Our merchants (business side) must have a direct phone number to their clients (customers side). When customers book a visit, we pass their mobile phone number to our merchants (with customers permission). It's because if anything bad happens (let's say, that vet by mistake gives a wrong medicine), they can react fast.

Question:

If we implement login/register with Apple ID, will we be allowed to ask additionally each our customer for their mobile phone? Regardless of their Apple ID settings?

Simple rule: we didn't get customers phone number -> we ask them to set it. Also, important information might be, we validate it because we send SMS with validation code.

Thanks in advance for your help, we are struggling with this since a while.

Best regards Jakub
