About NPA 888

When 800 ran out in 1996, the FCC opened 888 as the second toll-free prefix. It's now the second-most-saturated NPA — over 98% of its 7.98 million numbers are in active use. New 888 assignments increasingly come from disconnect aging, not from fresh inventory.

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.
