I´ve got this picture from garyschmidt5@myself.com.
He saw this plate in Riga/Lithuania and wants to know what it could be.
I´m not able to identify it. (Is it possible, that Netherland´s diplos have the ´CD´ not only at the beginning ?)

Portugal diplomat? In Holland there are hyphens between the letters. 80-CD-67
Jacco
Yes, it might be an NL diplo for International Organisations, but usually they have hyphens nn-CD-nn
Portugal diplomats shoul be in the format nnn CD nnn with leading zeros when required
Could be originating from Cyprus..
70 CD 02 Yes – the Cyprus CD series from 2004 would seem to be a possible answer – except that they don’t use lead zeroes. This car would have been 77 CD 2 in the CY CD system . And THAT is assuming they had issued up to 77 embassies/international orgs. They haven’t – they are only up to 60.
(60 missions, to a small island! Plenty of jobs for the boys, eh?)
