[Breaking Bad/Better Call Saul] How would the disappearer go about doing what he does?

Ok so he puts you in a truck and takes you somewhere, lots of traffickers can do that. The tricky part is that the new social security number he gives you is apparently good enough to allow you to go to the Hospital and have it checked with no issues.

The only possible explanation is that he has serious connections.

As for the exact mechanism, there are a few possible explanations. One {purely hypothetical} possibility is that at some point, a fake identity is "born." All the documentation is filed properly, birth certificates, Social security, etc. The person doesn't actually exist, they're just being planted in the system as early as possible. Then, 20-30 years later, a client who needs to be disappeared comes along, and the disappear-er fabricates the details to make the two people one. All the legitimate aspects of the non-existent person are handed off to the client, and they assume the identity of a nearly blank slate, a non-person born exactly for that purpose.
