Czech Postal System--mail forwarding

I have a Czech friend who lives in the Czech Republic who recently moved within the country, but I don't have the new address.

Will their postal system forward mail and packages to a new address and if so, for how long after the change of address?

 

Also, what is the best way to send a small money gift to someone in CZ?

 

In the Czech Republic, mail forwarding is a paid service (usually the Czech Post does not know someone's new address, it is not a secret police).

For how long? As long as someone pays for it.

Is it different in the USA?

 

Thanks for your response. I'm not sure I understand the answer.

If you are not from the US, in the US we provide our post office with our new address and the mail is forwarded for a year. There's no extra cost for letters, but I'm not sure about packages.

If someone in the Czech Republic moves, do they tell the post office to forward mail?

You say it is a paid service? How much do they charge?

 

Mail forwarding is optional and paid service.

100 CZK/month

 

So what happens if I mail a letter to someone's old address and they did not buy the mail forwarding service?

Will the letter be returned to me?

How can I know if they have this service, since the only way I can communicate with them is by mail?

 

Probably yes.

Try to send them a letter and wait.
