The Pasporta Servo (English: Passport Service) is a hospitality exchange service available both online and in print that lists people in Esperanto culture who are willing to offer free homestays to speakers of Esperanto.
[2] The platform is a gift economy; hosts are not allowed to charge for lodging.
Guests using the service are encouraged to speak only Esperanto with their hosts.
In 1966, psychologist Rubén Feldman González started the Programo Pasporto, a lodging service for Esperanto speakers, in Argentina.
[citation needed] In 1974, the Pasporta Servo directory was first published, listing 40 hosts.
