SHA-256 Hashing Tool

Pick a parameter, enter the raw value, and the tool applies the correct normalization for that field before hashing — so the output matches exactly what ad platforms expect.

ParameterValue

Trimmed and lowercased before hashing.

SHA-256 Hashed Value

Note

Customer information parameters that include Personally Identifiable Information (PII) need to be hashed using the SHA-256 algorithm before sending. You should only send PII if the customer has given the appropriate consent.

Advanced Matching Parameters

Every parameter is a string($sha256) — normalize the raw value as described below, then hash it with SHA-256.

Trimmed and lowercased before hashing.

Example: [email protected]
SHA-256: 55e79200c1635b37ad31a378c39feb12f120f116625093a19bc32fff15041149

Firstname

Lowercased before hashing.

Example: john
SHA-256: 96d9632f363564cc3032521409cf22a852f2032eec099ed5967c0d000cec607a

Lastname

Lowercased before hashing.

Example: doe
SHA-256: 799ef92a11af918e3fb741df42934f3b568ed2d93ac1df74f1b8d41a27932a6f

Phone number used for Meta

Example: f
SHA-256: 252f10c83610ebca1a059c0bae8255eba2f95be4d1d7bcfa89d7248a82d9f111
