How do I change my mailing address or cancel my subscription?

If you receive PT through your membership in one of the professional societies in the AIP federation (AAPM, AAPT, AAS, ACA, AMS, APS, ASA, AVS, Optica, and SoR), please contact that society to update your subscription information.

If you have a direct subscription to PT, you can update your information on the Account page or by submitting a request to our contact form.
