New 203 numbers are nearly exhausted, so carriers now issue numbers in the overlay code serving the same cities and rate centers.
How buying a 203 number works
- Pick any number above, or search the full 203 inventory.
- Sign up for a Phone2 plan (from $7/month on annual billing). The number is included, with no one-time purchase fee.
- Start calling and texting immediately from the mobile, desktop, or web app.
Unlike number marketplaces that sell 203 numbers for $99 or more one-time, Phone2 includes the number with the phone service itself. 30-day refund guarantee, and you can port the number out any time.
