The Cabinet approved a bill which would make it mandatory to show identification when buying lottery tickets.
The bill, which need approval by the government and President, will come into effect in a little over a year and would help those who have self-imposed limits on playing the lottery. The voluntary list is currently only in effect in casinos.
The limit will also extend to sports betting, but not to "scratch and win" cards.
Taivo Põrk, of the business and accounting department of the Ministry of Finance, said Estonia does not have many lottery addicts, but the problem is very real.
"The danger is there and we found that personal identification would not take too much time or cause too many problems," he said, adding that there a numerous cases of people buying hundreds of lottery tickets, or spending thousands of euros in a few month.
