I received a hand delivered letter today informing that our commune is to take part in the census. Thankfully there was a letter in English explaining how it is conducted and more or less what we are expected to do. Eventually I worked out that it must be done by this Tuesday.

There is the option of doing it online, and to that end, there is an identifier and a password to get into the online form page. These are printed as part of the letter and clear to understand. Then the fun begins. There are two more sets of characters that identify something else (location maybe?) and these have been hand written into little boxes. The problem is I can't decipher them all. The
zeros are easy, but the rest are so unlike English language I can't tell if they are numbers or letters. I think one of them is a
seven because there is a horizontal line across what looks like a French
one. Then there is either an
H or a
four. Then a couple of others that I can't liken to anything at all. I have been Googling French handwriting examples and getting no useful information. Clearly whoever filled in the boxes had loads to do and veered a little far from the examples that turned up in my search.
Any idea what to do to identify these characters for certain before I use them on my online census form?
Before anyone suggests........ We have no French neighbours to ask, and when we have asked the French speaking English ones for help in the past they suddenly claim to know very little so we no longer ask.
