May 2004 - new GSM numbers

+592 640xxxx was introduced for GSM mobile cellular numbers.

GT&T GSM ranges become: +592 640xxxx, +592 641xxxx, +592 642xxxx, +592 612xxxx.

Source: GT&T announcement (12 May 2004, via ITU).

11 February 2004 - new Georgetown numbers

+592 218xxxx range was added to Georgetown on 11 February 2004. This is apparently a new range, rather than a change to existing numbers.

1 February 2001 - national renumbering

Guyana has switched to a new 7-digit national numbering plan, replacing the previous system of area code plus subscriber number. This means area codes have been eliminated in favour of a national subscriber number of consistent format.

Some areas changed to the new national 7-digit system since 15th January 2001. The major centres of Georgetown and New Amsterdam switched for 1st February 2001.

There is a three month permissive period for callers into Guyana during which the old numbering will be allowed as well as the new numbering, presumably expiring approximately May 2001.

Details on exchange codes and the conversion to the new numbering are available at:
