The National Frequency Management Unit is responsible for administering the national public telecommunications 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 is any integer 2-9 and X is any integer 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.
