To donate by check: mail to the address above. The FSF can accept Canadian checks; please ask your bank to add a corresponding US bank on the check so that we don't get charged fees for depositing it. If you plan to donate in any other currency, please contact info@fsf.org for details on how to make a transfer from a foreign bank account. If it is a directed donation (e.g. for a sponsored project like Replicant), please write that on the memo line of the check. See more ways to donate to the FSF here.
