About NPA 800

The 800 prefix opened in 1967 as the world's first toll-free area code. By 1996 it was completely exhausted: every assignable number had been claimed and the spare pool dropped to zero. Today, the only way a 1-800 number changes hands is when someone disconnects an existing one, and even then the disconnect aging period and the well-known 'shark' RespOrgs make these moments fiercely competitive.

Status decomposition over time

Every toll-free number sits in exactly one status: working (in active use), assigned (allocated but not yet routing), reserved (held briefly during pickup), disconnect (aging out before returning to spare), transit (mid-port between RespOrgs), unavailable (held by Somos), or suspend. Watch the mix shift as the prefix has matured.
