The Pool

Week ending October 24, 2026: 85.0% of toll free numbers are in use. 888 has 35,342 spare left, and 800 has shown at most 1 spare in any of 282 weekly reports since October 28, 2017.

Every toll free number in North America lives somewhere on a spectrum from working (in active use) to spare (waiting to be assigned). This is the inventory side of the industry, what's left, what's churning, and how fast the pool is filling up.

Weekly net pool growth · last 2 years

Each bar = one week. Green up = the spare pool grew that week (more numbers got freed than assigned). Red down = the spare pool shrank (more numbers were assigned than freed). The pool's been losing ground steadily · the disconnect tide hasn't been keeping up with new assignments.

How long until we run out?

Somos publishes six different exhaust-date forecasts every week, each based on a different historical window (1, 2, 3, 5, 7, and 9 years). They wildly disagree. The 12-month forecast says we have 2 years left. The 9-year forecast says decades. See how predictions have evolved →
