You may choose to activate the AAVS function within 30 days from the issue date of the letter through one of the channels below:


  1. Bring along the activation letter, the original copy of your identification document and the registered Octopus in person to any MTR Customer Service Centres to activate the AAVS function. After the activation of your AAVS service, MTR staff will keep the activation letter for record.
