Duplicate leads and cookies

[Anonymous]

Do duplicate lead records have the same cookie association or different? If we merge these two records, I assume the cookie from the one that had the most recent activity will override the other?

Duplicate leads are only duplicates to you. Until they're merged, they operate fully independently, with different associated web session(s) and different activity logs.

If we merge these two records, I assume the cookie from the one that had the most recent activity will override the other?

Any lead can have, in practice, an unlimited number of cookies, one for each device/browser/profile they use. I've leads with 100 associated cookies. You shouldn't think in terms of a singular "cookie."

When leads are merged, their activity logs and associations are also merged.

Sanford Whiteman‌ will those cookies that were associated with the 'losing' record in the merge be reassociated with the 'winning' record?

[SanfordWhiteman]

Yes, both cookies end up associated.
