How to validate phone number length before customer checkout?

[Keries]

Hi here

May i know any way to do the phone validation before the customer check-out? 

Or any warning msg can be trigger when the number length is more than required length?

Keries,

Shopify Flow is now available on all plans and while it will not stop the order it is under your control and you can tag the order or apply actions.

So you an add a flow based on an empty order.customer.phone

I don't know how to use the phone number length though as a criteria. Does anyone else have an idea?

Thanks

Hi Derek,

Somehow the Shopify Flow said it doesnt applicable to my Store. Do you know
why does this happen as you said it applies to all plans.

thanks

Keries,

Just closing this loop - Yes, you can use Shopify Flow on the Basic Shopify plan. Shopify Flow is a free app available for stores on the Basic, Shopify, Advanced, and Plus plans. You can install it from the Shopify App Store.
