I got a new French passport as the French Embassy in Bangkok. What do CLD and CLR stand for on a delivery certificate ("attestation de remise") when getting a new French passport?
I don't have any official source or reference for this, but it's easy to guess that they are location identifiers, probably the place where you made the application (CLD: Code Lieu de Demande maybe?), and where you will get the passport back (CLR: Code Lieu de Remise?), usually the same.
On yours the code is
THA01, which probably means
TH = Thailand,
A = Embassy (Ambassade),
01 is a sequence number obviously not used for the embassy but probably used for consulates.
Other examples seen on the web use 5-digit numbers which are probably postal codes, INSEE codes, or other similarly derived identifiers, as the first two digits are the number of the département which matches the place of delivery.
All in all, it does not seem to affect you in any way. The CLR is "translated" in clear in item (9) on the attestation de remise, and is also likewise present on the bio page of your passport under Autorité.
