Guyana is +592
A local writes 612 3456 — the dialer below turns that into what you press.
Guyana looks Caribbean but dials like its own plan: seven digits after +592, no trunk prefix, mobiles in the 6 range. The quirk is the way out, which is 001 rather than the usual 00, a habit shared with few neighbours. From abroad just dial +592 and the seven digits.
Seven digits with no trunk prefix; mobiles begin 6, Georgetown landlines 2.
