Travellers qualify for a concessionary bus pass then they have reached retirement age or if they are disabled.
From February 2, buses will have an improved card-reading system which will check whether concessionary bus passes are valid.
There are cases of passes being sold on or lost passes being used fraudulently, which the new system will help counter.
Wiltshire Council is holding an amnesty until February 2, for people to arrange for a new pass to be issued or return the old pass.
During this time if a pass is shown which is no longer valid, the driver will tell the passenger that the pass must not be used again but they will not be charged for that journey.
A pass is not valid if:
•The holder has informed the council the pass has been lost or stolen
•If it has previously been used fraudulently
•The holder is no longer entitled to concessionary travel
•If the council has written to the holder about the pass and the letter has been returned by Royal Mail
•If the council has written asking for up-to-date proof of eligibility or asking for the pass to be returned.
John Thomson, cabinet member for transport said: “For many people the concessionary bus pass offers a real lifeline but there are cases where it is used unscrupulously and we want to put a stop to this.
“We’re offering this amnesty period so if people discover their bus pass is not valid they can get in touch with us and we can replace it in good time.”
People who are told their pass is not valid should call Wiltshire Council on 0300 456 0100 or email

If it is necessary for Wiltshire Council to issue a replacement bus pass there will be a £5 charge
