As you are most likely aware, UEFA EURO 2020 has been postponed until 2021.
Previously issued FAN IDs are not valid for attending UEFA EURO 2020 matches nor for entering and leaving Russia in 2021. All spectators should obtain an updated FAN ID to attend UEFA EURO 2020 matches in Saint Petersburg as well as to enter and leave Russia without a visa.
To confirm the data, all spectators who have previously filled out applications for a FAN ID should have received an informational message by email. More information is available on the official website: www.fan-id.ru.
