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.
