Members’ Fees

Annual fees: the total 2027 annual ODA members’ fee assessment amount is $16,745,300. Members’ fee assessments are calculated based on system usage from the previous annual billing period, specifically the total number of notifications received between December 1, 2025 and November 30, 2026. Each notification delivery medium (e.g., each email address or other delivery method) is counted as a separate notification for assessment purposes. Members should consider this when adding or updating notification delivery methods, as additional delivery mediums will increase the total number of notifications received and may affect future annual fee assessments. Fee assessments are issued to Members annually. Members who received fewer than 500 notifications during the previous annual billing period (December 1, 2025, to November 30, 2026) did not receive an annual assessment invoice in 2026.
