It's very clear in the ARIN region as well. From the ARIN Number Resource Policy Manual (NRPM), <https://www.arin.net/policy/nrpm.html#four11> - "4.1. General Principles 4.1.1. Routability Provider independent (portable) addresses issued directly from ARIN or other Regional Registries are not guaranteed to be globally routable."
