Understanding ECI Series IDs: A guide to series ID usage and formatting
When working with data from the Employment Cost Index (ECI), each series available will be assigned a specific series ID code. These codes are 17 digits long with each part corresponding to a feature of that series. Using the codes listed below, users can put together each portion of any series ID used in the ECI.
Understanding the different components of series IDs allows users to quickly find series using the Series ID shortcut, create custom database query code using the BLS Public Data API, and reference IDs in existing literature. Series ID codes are used for more programs than the ECI; the Series ID Format page contains information on each ID format used by any BLS program.
- Publication Prefix (AA) ▸
- Every BLS database uses a unique prefix to identify the specific publication. ECI Series are labeled CI; other NCS series prefixes include CM for the Employer Cost for Employee Compensation and WM for the Modeled Wage Estimates; others can be found on the Series ID Format page.
- Seasonal adjustment (B) ▸
- S for seasonally adjusted and U for not seasonally adjusted series.
- Ownership (C) ▸
- Indicator of whether the establishment represents all workers, only those in the private sector, or only those in state and local government. For more information on exclusions from the survey scope, see the Handbook of Methods.

While it is easy to break a series down like this, it’s also important to know that not all combination of series ID codes will result in a published series. Not all possible estimate combinations are published; some estimates are only available for certain ownerships, industry groups, etc.
Example
Here is a breakout of the series ID for 3-month percent change, not seasonally adjusted, in wages and salaries for private industry union workers in goods-producing industries:
CIU202G000000510Q
CI: ECI
U: not seasonally adjusted
2: private industry
02: wages and salaries
G000: goods-producing industries
000: all occupations
510: union workers
Q: 3-month percent change, current dollar
For More Information
Each BLS series has a unique series ID, and while many have the same components, most have different codes. To find a series ID format for a different BLS program, see the Series ID Format page.
For more information on the Employment Cost Index (ECI): data can be found in table form or through the database search tools, factsheets provide information on key concepts, and the Handbook of Methods can provide more information on all National Compensation Survey (NCS) products.
