Yo-yo numbers
If you don’t pay your phone bill to the phone company providing the service on your toll free number, they will at some point have to disconnect the toll free number. Sprint in particular seems to do this if you’re only one day late. And just to make it worse, they’re the only Resporg that we’re aware of that actually disconnects numbers all the way into the national SMS800 database too.
I guess they think the threat of actually giving away your toll free number is stronger than just shutting it down so they’ll get paid faster. (That’s Sprint customer service for you!) Unfortunately this disconnecting and reconnecting process tends to create what we’ve named Yo-Yo numbers, not to mention this is how Sprint loses numbers on you too.
Yo-Yo numbers will tease you because they get disconnected repeatedly but also get reconnected, often within a few days or weeks and they don’t usually make it all the way through the disconnect process. We’ve programmed our system to label them as Yo-Yo numbers when they get disconnected to try and keep customers from getting their hopes up inappropriately.
If you use Sprint, you should really try to check your number monthly if possible and be sure to reconnect it if they disconnect it because it’s easy to forget that and lose your number from this.

[…] YoYo numbers - These are numbers that get disconnected and reconnected repeatedly, usually by Sprint. We label these when they are disconnected so that anyone backordering them understands that there is a high probability that they will be reconnected for the original owner before completing the aging process.

Here’s a good example of a Yoyo number.

It was one of the numbers we put up the history for in an article about numbers being listed on ebay.
