ENS GB FAQs

Q: Why am I unable to obtain the local reference number and commercial reference number when creating an ENS?
A: Fill out the local reference number before submission when creating a new entry. If you duplicate an entry, there is a chance that the previous entry's LRN may be carried over, which cannot be accepted by HMRC. In such cases, update it to a unique number before submission.

Q: Why can't I submit the ENS because of unauthorized access?
A: Reauthorize yourself for ENS submissions. Follow these steps:

• Go to Settings > HMRC Authentication > HMRC User Authentication.

• Log in to the HMRC Gateway using your credentials.

• Ensure you are using an Organizational EORI, as ENS only supports organizational EORIs. Also, ensure you have subscribed to use the ENS service from HMRC.

Q: If I create one ENS with multiple items for the same truck (groupage), can I submit it against multiple Import MRNs when creating the GMR? Or do I need to create separate ENS entries for each Import MRN?
A: According to HMRC, S&SGB permits multiple consignments in a single ENS declaration, provided that all consignments follow the same route throughout their journey, from the country of origin to the final destination, and that all required details for each consignment are provided at the item level. 

Q: What does the error "The content of element 'PERLODSUMDEC' is not complete" mean?

Q: Is it possible to add a new item by duplicating an existing one?
A: You can achieve this by duplicating the row while changing the item information. Each row will create another item:

• The first row will create an ENS with one item.

• The second row, with the same header information but different item details, will insert the second item.

• This process continues for all additional items.

A: Due to a network, browser, or temporary server glitch, the initial submission did not complete successfully on the first attempt. However, the request was still sent to HMRC, meaning the LRN (Local Reference Number) was registered with them.

A: No, if you fill in an ENS declaration using IDP, it still counts as one declaration, not two. User Access: The 5-user limit means 5 individual logins, not device-based restrictions. Each user will have their own credentials for access. 

Q: Is it possible to create an ENS using just a Carnet ATA and an EU export document, without including a GB import document?
A: If the documents you mentioned contain enough information required for the ENS GB dataset, then yes, you can proceed with that, including the CDS import document.

This is our AI-based feature that extracts information from documents and automatically fills out 99% of the declaration data in your ENS entry.

A: The issue may be with the CWP additional document. Your are required to add authorization at the header level for this document, including the EORI of the authorisation holder.

Q: What is the cause of "business" error related to Number of Pieces (box 31)?
A: For UNPACKED package types, "Number of Packages" should not be used. Instead, "Number of Pieces" is required. Follow the UNECE recommendations for the correct field usage.

Q: Why does the system reject the DUCR format when submitting export declarations, even though it’s been used in the template?
