Interpret your AWS bill and usage reports for CloudFront

Once you have the billing report and the usage report, you can use this topic to understand how to interpret each CloudFront charge that appears on your bill and the corresponding usage type for each charge. This topic includes the codes and AWS Region abbreviations that can appear on both reports.

Most codes in both columns include a two-letter abbreviation that indicates the location of the activity. In the following table, region in a code is replaced in your AWS bill and in the usage report by one of the following two-letter abbreviations:

AP: Hong Kong, Philippines, South Korea, Taiwan, and Singapore (Asia Pacific)
AU: Australia
CA: Canada
EU: Europe and Israel
IN: India
JP: Japan
ME: Middle East
SA: South America
US: United States
ZA: South Africa

For more information about pricing by AWS Region, see Amazon CloudFront pricing.

Notes

This table doesn't include charges for transferring your objects from an Amazon S3 bucket to CloudFront edge locations. These charges, if any, appear in the AWS Data Transfer portion of your AWS bill.
The first column lists charges that appear in your AWS bill report and explains what each means.
The second column lists items that appear in the AWS usage report and shows the correlation between bill charges and usage report items.
