How to add DOB to customer notes in the sign up form?

Topic summary

Issue: DOB (date of birth) was added to the sign-up form, but it is not populating the customer notes; the “birthday” note appears blank.

Actions and references:

  • A community solution link was provided. The requester confirmed they implemented it, but the birthday still doesn’t input into notes.
  • The site URL was shared, and the responder tested it, indicating the calendar input works and DOB appears in the admin customer record (screenshots provided).

Current development:

  • The requester reports the date appears in the wrong order in notes and wants the format set to DD/MM/YYYY.
  • The responder states this requires theme customization and code changes; CSS alone cannot fix date formatting. They advise checking the DOB-related code/files.

Key details:

  • Images/screenshots are central to understanding (calendar icon, admin panel showing DOB).
  • Technical terms: DOB = Date of Birth; customer notes = a field in Shopify customer profile.

Outcome and status:

  • No confirmed resolution. Next step is to review and modify theme/code handling the DOB field to ensure it saves to notes and formats as DD/MM/YYYY.

Hi, I’ve asked this question before but didn’t get a response. I had code added to my website where the DOB would be added to the sign up form. Which it has been. However, the DOB is supposed to be added to the customers notes? But it isn’t? It just says birthday and is blank?

@HEALINGANDHER ,

You need to have customization on your theme. I have to check the files and codes. there is no option for CSS only.

Check your code for DOB, may be you will find the solution.

Where do I look?
