The National Frequency Management Unit is responsible for the administering the national
numbering plan and all other numbering resources assigned to Guyana.
Guyana's national public telecommunications numbering system is based on a standard seven (7) digit
numbering plan. This numbering system became fully effective from February 1, 2001, after making the transition
from a hybrid 5, 6, and 7 digit plan.
Administration of the national public telecommunications numbering system is done in accordance with the
National Numbering Plan Guidelines.
The format for the national numbering plan is NXX XXXX, where N can be any integer from 2-9 and X can be any integer from 0-9.
The first three digits of the of the national number represent the billing area code, while the last four digits
represent the subscriber line number.
Since the number resources, as structured, is finite, it must be utilized in the most efficient way.
Application for number resources from the national telecommunications numbering system can be made via the Application for
Number Resources
