Ad Manager enables you to use third-party ad technology vendors for
various functions identified
[here](https://developers.google.com/third-party-ads/). Some technologies can prevent unwanted vendors from running on
your site, while others may increase demand flowing through the system.

Third-party vendors undergo a business review. Google does not verify
or guarantee the technical implementation of these vendors.

There are two types of allowed vendors on this list.

**No declaration needed**
These vendors do not need to be explicitly declared
('No' in the declarable column below).

**Declaration needed**
These vendors need to be declared ('Yes' in the declarable column below),
in the [RTB BidResponse](https://developers.google.com/authorized-buyers/rtb/response-guide).
This is typically because the technology needs publisher implementation
to work (e.g., expandables), or it could be disruptive to a publisher's
pages.

The following vendors can serve third-party ads on the Google Ad Manager platform in all regions unless otherwise noted below.

Please note which vendor is allowed as a third- or fourth-party call.
Please also note that, while this list is being constantly updated, we
do not guarantee that product offerings, platforms or vendor types are
fully up to date. You should always reference our [specification pages](https://support.google.com/adwordspolicy/answer/94230)
to ensure the ads you want to run are in-line with the latest
requirements, and you should contact the vendor directly to find out
about their latest products.

Additional controls are available for European regulations. See
[vendor
information for European regulations](https://support.google.com/dfp_premium/answer/9012903).

The vendors permitted to make **third-party calls**
are generally of the following type:

- Demand Side Platform, Agency Trading Desk, Ad Network, Ad Exchange, Standard Ad Server \& Rich Media Vendors.

The vendors permitted to make **fourth-party calls** are generally of the following type:

- Research products, which include Analytics/Performance, Brand-Lift Studies, \& Verification Services.

<br />


Product Name - Company Name
:   This is the product name of the certified company. If the company name differs from the product name, it is listed below in italics.

Vendor Type
:   This is a business model classification for the vendor's type. This classification is meant to inform third/fourth-party call decisions and is in no way an indication of a business' strategy or competency beyond this context.

GDN
:   A 'Yes' in this column indicates that a vendor can access [Google Display Network](https://support.google.com/adwords/answer/2404190) inventory via the Google Ad Manager. A 'No' in this column means that a vendor is restricted to Ad Manager non-Google Display Network inventory.

Declarable
:   Whether this vendor needs to be declared.

Vendor ID
:   The numerical identification used by the vendor_type field in the BidResponse. See the [complete list](https://commondatastorage.googleapis.com/adx-rtb-dictionaries/vendors.txt).
