I think maybe “auth info” was one of the missing pieces of information.
All Registries whether thick or thin have the authinfo already, it's not needed for "adding contacts" There are 2 main issues with the escrow files - format of the data and it not necessarily being the data you want passed to the registry * the standard for escrow data means it's not obvious/possible/reliable to determine city/state type information when it's compacted into 1 field * if the contact data is to be privacy/proxied, the privacy data is what you want in the registry whois, not the "real" data which is what is in the escrow files Both of those are ultimately solvable though, many of us have successully pulled in escrow data as registrars over the years, and the privacy issue could be coded around easily, but they impacts enough registrars and registrations that I fully understand not going that route Rob
