How to fix Bluedart "CRTOMOB length can not be greater than 15" error?
This error appears when the customer mobile number on the order is longer than 15 characters.
Why this happens: Bluedart's API caps the customer mobile field at 15 characters. Numbers with spaces, dashes, or an extra country-code prefix easily go over.
How to fix:
- Open the affected order in Shopify.

- Edit the customer Phone field — remove spaces, dashes, and any duplicated country code.
- The final value should be a clean 10–13 character number (e.g. +919876543210).
- Save the order and retry the shipment from ILS.
