Examples.

For commodity and FD-ID indexes, series identifiers combine a "wpu" prefix (not seasonally adjusted) or a "wps" prefix (seasonally adjusted) with a commodity code.
Commodity code Provides data for:
wps141101 Passenger cars, seasonally adjusted
wpu141101 Passenger cars, not seasonally adjusted
wpufd4 Final demand, not seasonally adjusted
wpsid63 Services for intermediate demand, seasonally adjusted


For discontinued commodity indexes, series identifiers combine a "wdu" prefix (not seasonally adjusted) or a "wds" prefix (seasonally adjusted) with a commodity code.
Commodity Provides data for:
code

wds019 Other farm products, seasonally adjusted

wdu0635 Preparations, ethical (prescription), not
 seasonally adjusted

wdusi138011 Stainless steel mill products, not seasonally
 adjusted


Current price indexes grouped by industry according to NAICS have series identifiers that begin with the prefix "pcu." After the prefix, there are 12 digits (the 6-digit industry code is listed twice) followed by up to 7 alphanumeric characters identifying product detail. Dashes are used as placeholders for higher-level industry group codes.
Industry-product Provides data for:
code current NAICS
series

pcu325---325--- Chemical manufacturing

pcu336110336110 Automobile and light duty motor vehicle

 practices and single-specialty group
 practices, general/family practice


Discontinued industry-product codes based on SIC combine a "pdu" prefix and "#" between the fourth and fifth characters of the product code. Series identifiers for the discontinued dataset use underscores as placeholders to complete a reference to an SIC industry group code of fewer than four digits. (All PPI industry-based indexes organized by SIC were discontinued with the introduction of NAICS in 2004.)
Industry-product Provides data for:

pdu28_ _# Chemicals and allied products

pdu331_# Blast furnaces, steel works, and rolling and

Price indexes for discontinued series grouped by industry according to NAICS have identifiers that begin with the prefix "ndu." After the prefix, there are 12 numeric digits (the 6-digit industry code is listed twice), and up to 7 additional alphanumeric characters that identify product detail. Dashes are used as placeholders for higher-level group codes.
