# DID Group Types

Use the DID Group Types resource to retrieve DID Group Type records available in the DIDWW
coverage catalog.

A DID Group Type defines a broad category of DID services supported by DIDWW, such as
local, mobile, national, toll-free, shared cost, or global numbers.

DID Group Types are used with DID Groups to classify DID inventory. Use them to filter DID
Groups by service category and identify the type of DID phone numbers available for a
selected country, region, city, area, or prefix.
