Hello Chris, and thank you for posting to our support center.
While our Ready to Ship page should alert you to company names that are too long, unfortunately it does not currently provide an alert about invalid phone numbers.
Normally you will see a red alert triangle listed on the Batch header in your pending Shipment queue, and also on the specific order within the batch. The link below illustrates what those alerts will look like.

I will be happy to mention your needs for an alert for invalid phone numbers, to our Product Management team. I also encourage you to post in our Feature Request Forum:
Feature Requests - Shipping: Orders, Labels & Shipments
Our community has considerable influence on the course of our development. The more interest we see for certain features or integrations, the more likely they will be added to our app.
We look forward to seeing you in the Feature Request forum and taking an active role in helping to shape ShippingEasy!
