NoWcard holders are being urged to check their travel smartcard in case it needs renewing.
Around 300,000 NoWcard bus passes in Cumbria, Lancashire, Blackburn with Darwen and Blackpool expire this year with most needing to be renewed by the end of March.
Lancashire County Council has sent letters to people whose passes expire in March or April explaining the renewal process.
If you haven't received a letter or haven't applied for your new pass please contact the NoWcard helpline on 0845 058 1096 or visit www.nowcard.org.
Passes that are not renewed before the expiry date will no longer be valid for free travel on bus services.
