I'm a little bit confused by one of the 'systems' on Localyte. It's the business of asking a question about your own area and being... to answer the very same question and be awarded points for this??? Seams a bit silly, or is it me? Having said all of this I in fact do have a question about Czech Republic that I would like to throw into the pot. It might not be seen as of much importance to a visitor but on the other hand I'm sure that a lot of people would consider it of great importance. OK here is the question / observation / information. All addresses in the Czech Republic have two numbers, one on a red plate and one on a blue plate. For example my address is Lamacova 911/29. Now on most correspondence only the 911 is quoted and yet if you are putting in an address in the GPS it will know the 29. Question: Why are there two numbers? Now I will start Googling to see if even I could find the answer ;) Cheers Mark.


City: Prague

Region: Central Bohemia

Country: Czech Republic


OK. Now I feel a bit bad but I did find something on this double number subject but to be honest I'm not convinced that this is right and I will be checking it out first thing in the morning.
This is what I discovered on Google.........

The street number often consists of two numbers separated by a slash. The first
number is a unique district-related building number which doesn’t depend on the
street where the building is located, the second number is the street number;

On the first part of the question, if you go to tab 'My Profile' and click on the explination of how Localytes are rated, you will find the following suggestion for writing and answering questions:

"NEW! - Posting Public Questions - Earn up to 100 Points per Question

Now you can also earn up to 100 points for posting "great" public questions. As an insider you may want to ask "great questions" about your location because this can help travelers, get insider knowledge. Yes, we like you to post questions and we encourage you to submit an answer separately as well, if you find a good answer before anyone else. Why are we doing this? Because, we want to be a research tool for every traveler looking for insider knowledge."

I thought if awkward at first, but then I thought about their explination, and I realized that if travelers read these, two things will happen. 1. they realize what kind of questions us Localytes can answer and 2. It gives all the locals a chance to post a variety of answers to a variety of questions. Rating the questions gives the peers the opportunity to help each other as well. I try to rate as many of other's questions as I can, and certainly try to reciprocate when someone else rates my questions, answers and travel advice and will continue to do so. I believe you do this as well. I feel a city with many highly rated Localytes with many questions answered inteligently is much more useful and attractive to the public than one that has only a limited number of people who just seem to be promoting themselves and not their city.

As for the address numbers, my wife compares it to the Zip code system where there are the first 5 numbers that are required for delivery, and the last four are designed to aid in bulk mailing and GPS. I am not sure, but this seems to coincide with your google explination.

Hope this helps.

Hi Mark .. first things first the number system - from what I understand the red one is the building number and the blue one is the "postal" address.

As to the matter of asking questions about the country you live in .. and in particular doing so when the individual asking the question has an "expert" rosette next to their name, I sent a private message to one person based in Prague (who may even reply here) regarding this matter - if you're such an expert why are you asking questions the answer to which you should already know.

If it is indeed to shore up or even increase their ranking, then IMO they ned to get out more.
Hi Jamie
Thank you kindly for your message. I'm smiling from ear to ear.
Regarding the building numbering system. I felt sure that there must be some extremely well thought through system behind it and I did ask the question with grave reservations and I've actually been plucking up the courage to ask on Localyte for quite some time now.
You see, the thing is that I have talked to my wonderful lady Dana (who is Czech) about this and she was not clear on it and actually never uses the 'house number'. In fact she didn't even remember that number of the building that she has lived in for twenty years :)
I really do appreciate the support that several members have responded with and now I feel happy that I asked the question.


My understanding is as follows;

The first number (i.e 442 or 991) is the building number, a unique number that was assigned to the building when it was built and registered in the kadastre (land registry) office.

The second number simply refers to the house number in the street, with odd numbers (1,3,5 etc) on one side and even numbers (2,4,6 etc) on the other

Hope this helps?
Cheers Andy
Thank you for the concise summary.
This only leaves me wondering why the first number is chosen to be used as the 'normal' mailing address rather than the actual house number.
Oh well....... It's Friday..... beer time!!!
i think because the mailman has to walk up / down the street and has to organize their bag ? Also because the blue numbers are easier to remember and also easier to understand ... Only on some of the "sidliste" they use the red ones, because the roads there arent quite easy to comprehend ....
Indeed, officialy you are supposed to put both of the numbers.
It is quite ineresting that in Prague the blue / red combinations happen to be almost unique - there once (before GPS) was a WAP application, where you would just write the two numbers of the closest house and the app would tell you where you were :).
I once had a funny story with a guy that was walking through Prague, preparing some documentation about buildings and he asked me what was the red number of our house. And I went "oh, it was some historical catastrophe, 1620 ?" Then I had a look and it was 1948 :).
Hi Mojzis
Very nice to meet you (in an electronic kind of way) and I thank you very much for your explanation and very good humoured story :)
Now please believe me when I say that I am writing this with a big smile and an imaginary question mark hanging over my head.
You say that the mailman (in our case a lady) has to walk up and down the street and I therefore fully understand that the blue number is more logical plus easier to remember.
Sadly this just leaves me confused once again because our address is Lamacova 911/29 but we only ever say 911... in fact I have just had my second business 'Rubber Stamp' made with that address...... it is at this point that the smile is beginning to drop from my face and I'm wishing that I had the stamps made with both numbers on.
My conclusion from all of this is that from now on I am going to write both numbers just as you say 'you' (as in the royal) are 'supposed' to put.
Kind regards
Mark, nic to meet you, too :-)
About your adress : i'd guess it is not that much of a problem, since the construction in your area happened all together, apparently, so even the "red" numbers are sequential. To see the "normal old town behaviour", have a look at this, for example : @@
and then change it for dejvicka 3 - the red number differs greatly, because the two houses were built in different times ....
Here in the village, we don't care, just one number does the job :) i dont even know which colour it is :-).
"you are supposed" - funny, ididnt find anything about it ... I was almost sure ceska posta required both numbers, but most probably they dont.
