register many branches under one vat number

In the name of the Allah,

I have a company registered under a single VAT number with the authority, and it encompasses three different Commercial Registrations (CRs), for example: 1122006273, 1183000641, and 1017000096, each representing a separate branch. I am using a cloud-based software solution, so all branches operate on the same server.

During the onboarding process on the ZATCA platform (zatca.gov.sa), I followed the necessary steps but registered only one device, which I activated on the server. When sending invoices to the API endpoint for reporting or clearance. I include the CR number of the branch that issued the invoice within the submitted invoice data.

Recently, I received an email from the authority indicating that my invoices are not fully compliant with the requirements of Phase Two of Electronic Invoicing (Integration). They emphasized the need to provide the correct CR for each branch and to ensure each branch is properly registered, with accurate entry of its unique CR identifier.

وحيث أنه تم ملاحظة عدم مطابقة فواتيركم لمتطلبات المرحلة الثانية من الفوترة الالكترونية - الربط والتكامل
ويتضمن ذلك:
· السجلات التجارية:

لابد عند اختيار معرف السجل التجاري ووجود سجلات تجارية متعددة، يجب على المورد إدخال السجل التجاري للفرع الذي يتم إصدار الفاتورة الضريبية منه ، لذا فإنه يجب تسجيل كافة الفروع التي يتم من خلالها اصدار فواتير ،وكذلك التحقق من الادخال الصحيح لخانة المعرف الخاصة بالسجل التجاري

After contacting the authority’s support line, I was informed that each branch must be registered on the platform separately. Therefore, I have the following questions:

Do I need to register a single device, given that there is one VAT number, or must I register one device per branch (in my case, three devices)?

If the three devices is required to register , could you clarify which step in the onboarding process allows me to enter the CR number of the branch ? So far, I have only seen a field for the VAT number.
Thank you in advance for your assistance.

Dear @usera

Thank you for reaching out & welcome to the community.

Kindly note that every device issuing invoices with the same VAT number should be registered.

Thanks
