NPA 888
Opened 1996 to relieve 800. Now nearly full.
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.
