It's possible you need to re-register with Aduanas. I had registered back in 2019, and EPS notified me I had to re-register this July when I was using their courier service. It had been quite a while since I had received a package, so am not sure exactly when my account needed renewed.Sure, I registered a long time ago. It's required. I don't believe the issue is with Vimenpaq although I can't say for sure. Vimenpaq was recommend to me by members here after I had bad experiences with LogicPaq and I have been using the former for about four years or so, averaging 10-15 packages per month although almost never via Customs.
