International Telephony Numbering Plan Resources
Due to the expansion of telephone number capacity to accommodate
pagers, fax machines, wireless telephony, and other new phone
technologies, numbering plans have been changing worldwide. Many
new area codes have been established; new service categories have been
established (for example, to accommodate GSM, personal numbering,
corporate numbering, etc.). Below we list several web sites that present
up-to-date information on the telephony numbering plans used around
the world. While we find these to be generally good resources, we
would note that URLs may change or become nonfunctional, and we
cannot guarantee the quality of information on these sites.
