How 900 Numbers work

To use a 900 numbers service, a caller dials a telephone number that uses 900 as the area code. Immediately upon connecting, the caller will hear a preamble explaining how the call will be billed. This is designed to allow the caller time to hang up before charges begin to accrue.

After this message, callers can be handled by a dedicated 900 number service center or directly routed to your company's offices or home office. 900 calls can be sent to landlines or mobile phones.
