Telephone field in customer account does not validate

[marctbb]

Preconditions and environment

Magento 2 versions tested:

• 2.4.6-p4 (with the default Blank theme).
• 2.4.7 (also tested with the default Blank theme).

Configuration:

• Stores > Configuration > Customers > Customer Configuration > Show Telephone: Set to Required.

Issue observed in both environments and themes.

Steps to reproduce

1. Go to My Account as a logged-in customer.
2. Attempt to Add or Edit the telephone field under account details.
3. Enter invalid input, such as text or symbols (e.g., "abc123" or "!@#").
4. Save the changes.

Expected result

• The telephone field in the My Account section should validate input to ensure it is a valid phone number (e.g., digits only, proper phone format).
• Invalid input should trigger an error message and prevent saving.

Actual result

• The telephone field in My Account allows invalid input (e.g., text or symbols) without validation.
• In the checkout, when retrieving customer details from the account, the invalid phone number causes errors during the shipping process.
• For example, UPS shipping fails to process the order due to incorrect phone number format.

Additional information

• Video evidence of the issue is attached for reference.
• The issue occurs regardless of the Magento version (tested on 2.4.6-p4 and 2.4.7) or theme used (Blank theme).
• This inconsistency between the My Account section and Checkout makes it critical, as incorrect phone numbers lead to shipping failures.

Hi,

Thank you for your response and for verifying the issue.

I have re-tested this scenario using a freshly installed Magento 2.4.7-p3 instance, and I can confirm that the issue still occurs in this version. I have attached a video recording demonstrating the exact steps and the error encountered when entering invalid input in the telephone field.

Key details of the environment:

1. Magento Version: 2.4.7-p3
2. Environment: Fresh installation, no third-party extensions or customizations

Steps followed are identical to those mentioned in the ticket.
The error persists when saving invalid phone numbers like abc123 or !@# in the customer account details. It does not trigger the expected validation message.

• Attached Evidence:

• Video of the issue reproduction in my environment

Could you kindly verify this on a Magento 2.4.7-p3 environment or provide any additional steps for us to align?

Looking forward to your feedback.

Best regards,
