Latvia: official electronic address (e-adrese) mandatory for all legal entities
In force since 2023-01-01 under the Oficiālās elektroniskās adreses likums for all legal entities in Latvia's registers (companies, associations, foundations, trade unions, etc.). Still relevant for 2026-2028: every newly registered entity must activate one immediately, adoption/usage is reported by DVI as still well below 100%, and automatic e-address assignment for newly registered entities is planned (not yet in force) by end of 2026.
Every company, association, foundation and other legal entity registered in Latvia, including newly formed ones — this covers essentially all businesses.
