Two Shropshire pubs that sold alcohol to under-18s are being forced to close for 48 hours in lieu of a prosecution.
The Eagles pub in Bailey Head, Oswestry, and the Carpenters Arms in Bridgnorth were warned during spot checks in July to check customers' age.
Trading Standards and police used underage volunteers to carry out a second spot test at the start of October which they both again failed.
Police said closing from 1700 BST would send their landlords a clear message.
Shropshire licensing officer Tony Mantle said after both pubs failed a test under-age purchasing operation at the end of July, he advised staff to introduce a Challenge 25 policy and be more vigilant in future.
"It appears they failed to heed the advice as a follow-up operation at the beginning of this month saw them fail again," he said.
Licensed premises that persistently sell alcohol to children can be fined up to £10,000 and have their licence revoked.
Mr Mantle said: "Trading Standards and the police will not accept sales of alcohol to underage young people. There are so many unseen ramifications in the short and long term."
