IPR - Authorisation by customs declaration

Good afternoon all, Currently having trouble getting an entry accepted on CDS under IPR (510000) without the IPO authorisation (EORI) number being declared, i understand that the C601 GBIPO Simplified uthorisation will need to be declared with XW, 00100 AI Statement also, however it always asks for the the authorisation to be declared. i have managed to get an entry accepted with security against a deferment account however the gov site mentions that the IPO should not be declared which i deem impossible?

Hi ross edwards,

I would advise contacting the Customs and International trade helpline on 0300 322 9434 with your query.

Thank you.
