DROP Consumer Deletion Lists
List selection should follow an identifier inventory, not the other way around. Choosing lists you cannot match wastes cycles; missing lists leaves requests unprocessed.
Start with an identifier inventory
Before selecting list types, map which identifiers exist in which system, at what quality, and how they relate to a consumer record. Names, dates of birth, ZIP codes, emails, phone numbers, mobile advertising IDs, VINs, and connected-TV or device identifiers each behave differently in matching.
| Identifier family | Typical matching consideration |
|---|---|
| High-precision; normalization of case and whitespace is critical. | |
| Phone | Country code, punctuation, and extension handling must be defined. |
| Name + DOB + ZIP | Usually composite; field order and formatting decide accuracy. |
| Mobile advertising IDs | Case conventions and ID resets affect coverage over time. |
| VIN | Stable and precise; often held in a separate system from consumer records. |
| CTV / device identifiers | Frequently held by vendors rather than in your own systems. |
Document, per list type, which of your systems can produce the required identifiers and which cannot. The gaps in that table are your implementation backlog.
