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.
