Consumer Price Index (CPI)

Updated 2024-07-29

The Consumer Price Index (CPI) is a measure of the average change over time in the prices paid by urban consumers for a market basket of consumer goods and services. It is a key indicator of inflation.

Role in Do-Not-Call Registry Fees

The CPI, specifically the average of the monthly consumer price index for all urban consumers published by the Department of Labor, is used to adjust the annual fees for accessing the National Do-Not-Call Registry (15 U.S.C. § 6152(d)(5)(A)). For fiscal years after 2009, the dollar amounts for these fees are increased by an amount equal to the original dollar amount multiplied by the percentage by which the CPI for the most recently ended 12-month period ending on June 30 exceeds the baseline CPI (15 U.S.C. § 6152(d)(1)(B)). Adjustments are only made if the change in the CPI is 1 percent or greater (15 U.S.C. § 6152(d)(3)).
