What is the _scsrid_r cookie?
_scsrid_r is an HTTP cookie associated with Snapchat's advertising platform, operated by Snap Inc. It appears on a website when that site integrates the Snap pixel or other Snapchat conversion-tracking tools, typically to measure the results of ad campaigns run on Snapchat.
The cookie is a session cookie (no fixed expiration date) and belongs to a broader family of Snap cookies with the „_sc” prefix used for identification and attribution within their advertising ecosystem.
What data it stores
The provider does not publicly document the exact structure of this cookie's value. Generally, cookies in the _sc family store a randomly generated identifier used to link a browsing session to a Snapchat account or interaction, such as an ad click or content view.
The data is sent to Snap Inc.'s servers for processing related to advertising and attribution purposes. Exact technical details (format, length) may vary and are not publicly documented.
What it is used for
The main purpose is to support measurement and optimization of Snapchat advertising campaigns: it helps associate a site visit with a prior interaction with a Snapchat ad, enabling conversion attribution.
For the website operator, this cookie contributes to performance reporting in Snapchat Ads Manager, showing which ads drove traffic or actions on the site.
Does it require consent?
_scsrid_r is classified as a marketing/advertising cookie, since it is used for tracking in connection with advertising. Under the ePrivacy Directive (as implemented in Romania through Law 506/2004) and the GDPR, this type of cookie requires the visitor's explicit, prior consent before it can be placed.
- The website operator must disclose this cookie in the cookie policy, naming the provider (Snapchat/Snap Inc.) and its purpose.
- The script that sets the cookie must be blocked until consent is obtained.
- Refusing consent must not block access to the site's content.
How to block or delete _scsrid_r
A visitor can manually delete or block this cookie through browser settings (Chrome, Firefox, Edge, Safari – per-site cookie management), or use browser privacy features that block third-party cookies by default.
For website operators, proper blocking means preventing Snapchat scripts from loading before consent is given. A CMP platform like CookieFix can automatically block the Snapchat script until the visitor accepts the marketing category, preventing the cookie from being set prematurely.
